Cyclone dust collectors have a number of advantages over ordinary dust collectors, the biggest being their ability to remove most chips and dust particles from the air stream before it even reaches the filter. This is the "first stage", and is accomplished by the conical shape of the collector body creating a centrifugal force that separates the dust and chips from the air stream and deposits them into the portable collection drum below. The drum can then be easily emptied without lengthy down time as a result of having to remove blower housings and emptying filter bags. The clean air stream continues up the center of the collector through the impeller and filter in the "second stage." The filter captures 99.9% of the very finest dust down to 0.2 microns. Since the same volume of air entering the dust collector must also exit the dust collector, our filters are pleated to maximize surface area and efficiency. Dust cake on a filter can also diminish performance. To overcome this, our filters have a brush system that gently removes the dust cake, placing it into a plastic collection bag for nearly continuous maximum filter performance. With all these things considered, cyclone dust collectors are clearly superior to ordinary dust collectors!

Why a Cyclone?

There are three critically important performance criteria for cyclones: • The amount of material the cyclone will remove from the air before reaching the filters • The filtering ability of the filters• The ability of the cyclone to continuously move a high volume of air

The "performance curve" shown here is a way to visibly see the real world performance of a dust collector. The x-axis is Static Pressure or SP (think Suction Potential). The y-axis of the graph is the volume of air being moved, measured in Cubic Feet per Minute (CFM).

When a restriction is placed upon a dust collector, such as connecting to a smaller diameter dust port or multiple lengths of pipe, the static pressure goes up while the CFM goes down (remember, CFM is what we really need to keep the dust in suspension). Many dust collectors have a very good CFM reading without any restrictions and when the filters are new, but when you try to use them with a system of elbows, blast gates, dust ports and lengths of pipe, their performance suffers.

So, just how important is static pressure? Well, first let's clear up a common misconception: Dust collectors are NOT vacuum cleaners. Vacuums have very high static pressure (suction) but relatively low airflow (CFM). The high suction is what enables them to pull dirt up out of the carpet. Remember the ads of the vacuum that could

*Note: The traditional unit for measuring static pressure is in-H20 or "inches of water." This dates back to the way pressure was first measured - using a U-shaped tube partially filled with water. If you blow lightly into one side of the tube, the water will rise on the other side in proportion to the pressure with which you blow. The distance the water rises is measured in inches, giving us the pressure in "inches of water." Modern pressure measurements are made with precision instruments, not U-shaped tubes of water - but for historical reasons, the unit of measure has remained the same.

pick up a bowling ball? That's suction. But try that with a dust collector and you had better be wearing steel-toed shoes. Dust collectors work differently than a vacuum. By moving LOTS of air at a fairly high speed, the wood chips remain suspended in air as they move through the duct work. If the air is too slow, the dust will fall out of suspension and start piling up in elbows or even in straight sections of pipe. So, compared to a vacuum that moves a small amount of air under very high static pressure, a dust collector moves huge amounts of air at much lower static pressure. Even to this day, we get calls from customers who bought one of our dust collectors and then plumbed their entire house, thinking they would use it as a central vacuum and "save a bundle." Needless to say, they did not get the desired result.

measuring airflowTo measure the CFM, a test pipe that is at least 10 times longer than the pipe diameter is connected to the inlet. A sensitive pressure gauge is connected to a small L-shaped instrument called a pitot tube, which is then inserted into the pipe facing into the airflow. The force of the air creates a positive pressure on the end of the pitot tube which is called the "velocity pressure." Static pressure is the other airflow component and is measured at a right angle or perpendicular to the airflow using the same pitot tube. Static pressure is a negative (suction) pressure. Using the velocity pressure, static pressure, and the pipe diameter, the CFM can be calculated using a universally accepted formula.

performance CurveTo evaluate and compare the performance of dust collectors, a series of measurements are taken of the CFM and static pressure, starting with the air inlet fully open and then making subsequent readings using a series of "restrictor plates" to slowly block more and more of the airflow. Restrictor

plates are basically wooden tiles with holes in them (i.e. 6", 5", 4", etc.) The plate is placed over the end of the pipe and the measurements taken. This is repeated all the way down to zero where the opening is fully closed. At this point the CFM will be zero and the static pressure will be at its maximum. By plotting this data on a graph with CFM on one axis and static pressure on the other, we can see how the dust collector will perform in the real world when it is connected to ductwork and multiple machines. Generally speaking, the higher the maximum CFM, the more machines you can run simultaneously; and the higher the maximum static pressure, the longer and more elaborate the ductworksystem can be.

testing and DevelopmentAfter more than two years of research and development, we released our first series of Cyclone Dust Collectors. We had a long list of design and performance criteria, and after countless hours, we were finally satisfied with what we had created. Our 1.5, 2, 3 & 5 HP models were very well received, and in 2007 we unleashed our 7.5 & 10 HP Cyclones. These beasts have all of the important features of our smaller models but with more capacity to meet the needs of larger industrial shops. Every aspect of these machines was put to the test, and we did not stop until we had the results we wanted. We have continued to make subtle improvements over time, like our noise reducing mufflers that do not reduce airflow, a drum liner bag system that makes emptying a breeze, new filters with replaceable filter elements, and our latest – the portable G0703 and G0703P models for the ultimate home shop cyclone dust collectors.

filterOne of the most important components to a cyclone dust collector, besides the cyclone design, is the filter. Our filter material is BIA certified and manufactured in Europe by one of the most respected filter manufacturers in the world. These filters offer very fine filtering ability using only the best non-woven polyester material available. They are certified to trap 99.9% of particles from 0.2 to 2.0 microns.

Our innovative filter cleaning system ensures optimum performance and long filter life. Inside the filter is a soft brush that gently sweeps the dust off the filters from top to bottom with a simple pull of the handles. Any dust coated on the inside of the filter is swept into the bag for easy disposal. With

this system you can safely and completely clean the filter as often as you like without damaging it. Our exclusive design also allows the filter to be easily removed and rinsed with water for more thorough

CycloneThe most important part of the cyclone system is, of course, the cyclone itself. We made ours from 25% heavier gauge steel than some of our competitor's, then we powder coated it for a good

looking, durable finish. But that doesn't make a great cyclone - performance does. We spent more than two years developing our design and believe it to be second-to-none in performance.

Many factors affect how well a cyclone separates the dust from the air: diameter, height, the angle of the tapered bottom, size and shape of the inlet and outlet, as well as the internal structure. There has been a great emphasis on cyclones in the last few years, and many things have been learned about what makes them work better. The inside of our cyclone is not just a round barrel like others, but includes features not found elsewhere. The enemy of a cyclone is turbulence and we have gone to great lengths to reduce it. We use an internal "air ramp" that helps prevent incoming air from creating turbulence in the existing air that is already circling, which increase performance. We tested many different designs, and those with an air ramp outperformed them all. We were so impressed with the results that we promptly filed a patent application for our design.

Recently, competitors stated their design features a "neutral vane" making their design better. In fact, their neutral vane is simply the inlet pipe inserted partially into the cyclone rather than stopping where it meets the cyclone wall. This technology has been used for years, but our air ramp represents the latest in engineering and is clearly

an improvement, as well as being more expensive to build. Our reinforced inlet is visibly different as well because it has been specifically engineered to enhance performance. The round inlet is transformed into a rectangle before entering the cyclone, providing a much better flow of air against the cyclone walls compared to round inlets, regardless of their internal length. A further look will also reveal that our inlet does not enter the cyclone at a 90° angle like others do. Careful studies and much experimentation showed us the best angle to achieve the highest level of performance. This angle is precisely matched to the natural flow inside the cyclone, effectively starting the cyclonic action earlier in the process. This, along with the extra length of the inlet, greatly reduces turbulence, thereby maximizing performance and efficiency. The bottom cone of the cyclone design is also critical. We experimented with dozens of lengths and outlet sizes until we had the one that worked best with our upper design.

Please refer to the specifications for each cyclone in the back of this brochure for any other considerations related to your shop.

cleaning. We strongly recommend you not clean your filter with compressed air — not only has it been proven to reduce the life of most types of filters, but it will also blow the very finest and most hazardous particles throughout your shop. Our clear filter bag offers distinct advantages over what others use as well, because you will quickly learn how often to clean the filters by seeing how much dust falls into a clean bag, without disassembling anything. A quick glance from across the room will tell you if the cyclone is overfilled. And since it seldom needs emptying, most people just tie it shut and throw the whole thing away instead of dumping it out!

Our filters are also housed within a steel frame to protect from the everyday "bumps and bruises" that happen when carrying large lumber around or just working in your shop. It may seem like a small thing, and perhaps it is, but that's exactly why we can't understand

why everyone doesn't do it. Filters are expensive, cannot be repaired and must be replaced if damaged — this little "insurance" can prevent an unneeded and unwanted expense.

Which Cyclone is right for you?We offer a wide selection of cyclones designed for home-sized shops up to commercial-sized operations. When deciding which cyclone is right for you, consider how many woodworking machines will be in use at one time, the length and relative efficiency of your duct system, and the physical limitations of your shop (e.g. ceiling height, power supply and available floor space, etc.). Even though we keep our prices as low as possible, cost is also a big consideration, especially when adding up all the parts for a duct system. Blast gates allow you to add more machines to a duct system and yet isolate them from the cyclone when not in use. This allows you to maximize

suction at individual woodworking machines, but requires you to open and close blast gates to direct airflow depending on which machines are in use at any given time. Woodworking machines require a minimum CFM or airflow in order for chips and dust to be carried away. This minimum airflow varies depending upon the type and size of machine. A good rule of thumb is roughly 300-400 CFM per machine for smaller capacity home shop sized machines and 400-800 CFM for larger capacity industrial sized machines. Please refer to additional information sources about dust collection duct design. An excellent resource on this subject is the W1050 Dust Collection Basics Book.

After sucking up this much dust, not even a teaspoon of fine dust made it to the filter!

Cyclone features pleated filterThe filter is one of the most important components of any dust collector. Ours are BIA certified to trap 99.9% of particles from 0.2 to 2.0 microns. They are pleated to maximize surface area and airflow, and have from 48 sq. ft. to a whopping 390 sq. ft. of filtering area, depending on the model. We also have an innovative cleaning system to keep performance high, and they are protected within a sturdy metal cage but can be easily removed for more thorough cleaning if needed.

Wall mounting

We wanted to give our customers a way to mount the cyclone to a wall, existing structure, or even a homemade stand, so we designed our blower housing to be dual-purpose. First, it had to be strong, so we used 11-gauge steel that is up to two times thicker than some competitor's. Everything is fully welded on both sides (no spot welds here), then powder coated for a durable and good looking finish. Second, we made the housing square and included mounting "keyholes" on the sides. This allows mounting to a wall or structure if you choose not to use a stand. However, before mounting to a wall consider that the noise generated by the cyclone will be amplified on the other side of the wall, compared to using a stand.

Collection DrumAll of our cyclones come standard with steel drums that are powder coated for a lasting, durable finish. They will outlast fiber

drums many times over. We added simple quick-release latches to secure the top instead of the difficult to use wrap-around barrel clamps some others use. A drum full of sawdust can be heavy and awkward to handle. If you've ever tried to slide a drum full of sawdust across a shop floor, you know what we mean. Casters, securely mounted to the drum bottom, make the drum easy to move. We also use a two-piece steel drum on all models 3 HP and up. Why two piece? So you can choose to use only the bottom portion if your ceiling height is limited. Of course, the collection capacity is reduced; but, the cyclone performance remains the same.

Collection bag systemWe offer plastic collection bags that make it super easy to empty the drum. Simply pop off the drum lid, remove the full bag, and dump it into the trash. The bags are made extra long so you can twist the top shut to keep dust and chips from spilling out. You can dump and reuse the bag or tie it shut and put it in the garbage – all with little or no mess. The secret of this system is a small vacuum tube connected from the cyclone cone to the bottom of the collection drum. This provides internal suction that holds the bag inside the drum. Without this feature, the bag would be sucked up into the blower from the negative pressure inside. These drum liner bags come in 3 different sizes to fit 30, 35, and 55 gallon drums.

switch and remote

Grizzly has always believed in the benefits of using a magnetic switch with thermal overload protection. We knew we wanted to use them on our cyclones, but that presented us with an unusual problem. Our customers appreciate having a remote control and a programmable timer. Rather than settle for "almost" we put the engineers to work and designed a remote controlled magnetic switch with a programmable timer. The cyclone can be turned on or off from across the shop, or set to turn off automatically after 2, 4 or 8 hours. Others charge hundreds of dollars for an optional magnetic switch or charge extra for a remote. We are the only manufacturer to combine both and supply them as standard equipment!

motor

All our cyclones feature heavy-duty TEFC Class "F" Motors that are rated for continuous duty. They are designed specifically for our cyclones and are not an "off the shelf" motor.

motor mount

Our motor bolts to a steel plate that attaches to the blower housing. This extra steel provides a more rigid mount that helps reduce impeller noise.

adjustable heightWe know many of you work in basements or garages with reduced ceiling height. One of our primary goals was to make cyclones available to those with restricted ceiling height. With this in mind, several models can be configured to fit under an eight foot ceiling. Full dimensions are available in the back of this booklet.

adjustable inlet positionThe body of our cyclone rotates in 30° increments to allow positioning the inlet right where you need it.

standOur 14-gauge heavy-duty steel stands are designed in two pieces to keep the entire package smaller, which saves you money in shipping. The stand is supplied at no charge on the 5 HP and above cyclones, and is optional on the others. The stands for the 1.5, 2, and 3 HP machines are adjustable for height if you need yours to fit under an 8' ceiling.

portabilityThe G0703 and G0703P have many features of the larger systems, but in a compact size that requires less headroom and are completely mobile with built-in casters. They feature a pleated, removable filter system with internal shaker paddles for maintaining filter efficiency, a remote control switch for activating from across the room, a roll away collection drum for easy dumping, and a 6" inlet for handling larger duct systems.

noise reducerWe designed these mufflers to offer a significant reduction in noise level without any loss in efficiency. They are standard on models 3HP and up and are optional on the others.

packagingIn addition to all of the performance based criteria we applied to our cyclone design, we kept in mind that they must be shipped to our customers. To keep shipping costs down, we designed many components to be collapsible and packaged them so they could be transported as safely as possible. What good is a Cyclone if it shows up to your door damaged?

Q. What is a cyclone dust collector?A. A cyclone dust collector is similar to a regular dust collector except it separates the wood dust and wood

chips from the air and deposits them in a separate drum for easy cleaning. Some refer to them as 2-stage, but that term is a little too broad and does not describe accurately what it is. Depending upon the manufacturer and their design goals, they can also do a tremendous job of filtering the fine dust particles that are often blown into the air by a regular dust collection system.

Q. how does it work?A. Cyclones have been around longer than many of us have been alive, and do not represent new technology.

They have been used in industrial applications and in agriculture for decades. It has only been the last several years that smaller shops and homeowners are taking a serious look at using cyclones. Their operation is actually quite simple, the air enters the cyclone and spins around in a circle forcing the dust particles to the outside. Here the air pressure is somewhat reduced and causes the dust to travel down the wall of the cyclone. The air continues to spin as it also moves down the cyclone. When entering the tapered portion of the cyclone, the air and dust particles must rotate in a smaller and smaller circle which further separates out the fine dust, forcing it to the outside were it continues to slide down towards the collection drum, eventually dropping in. Our cyclone does an excellent job of separating the fine dust out of the air by reducing turbulence inside the cyclone. Turbulence inside the cyclone "stirs-up" the air which keeps those fine dust particles in suspension rather than dropping out of the air. A properly designed cyclone will separate nearly all the coarse and fine dust from the air allowing very little to pass through the cyclone into the filter. Turbulence inside the cyclone is its worst enemy. Our design significantly reduces turbulence thereby increasing performance.

Q. Why would i want to spend the extra money over purchasing a regular dust collector?A. The two big reasons to purchase a cyclone over a regular dust collector would be convenience and health.

Emptying the caster equipped drum is far more convenient then removing a bag and reinstalling on a regular dust collector (and faster, too). Some will opt for having multiple drums, so the full one can be rolled to the side and immediately an empty one rolled into position, and the cyclone put back into service. As for health benefits, the extremely fine filtering capability helps reduces the hazardous fine particle dust in your shop. With that said though, it would be unwise to ignore established safety precautions and respirators should still be worn.

Q. What is static pressure?A. Static pressure (SP) is the difference in air pressure between the air inside the duct and the air outside the

duct. The result is the suction that allows the dust collection or vacuum system to pick up chips and dust. If you take your hand and move it slowly towards the opening of a vacuum cleaner hose, the hose will pull harder and harder at your hand the closer it gets. When your hand completely covers the opening the static pressure is at its maximum. At this point the airflow (CFM) goes to zero. Static pressure is not suction, but it is what causes suction. The higher the rated static pressure, the higher the suction potential. So for a simple, brief definition, static pressure is the amount of suction potential that a dust collector (or shop vac, or vacuum cleaner, etc.) has. It is worth mentioning that CFM goes down as the static pressure goes up. A good dust collection system will have enough static pressure or suction to pick up the largest chips produced and still have high enough CFM or airflow to keep them moving and not settle in elbows, vertical sections, etc. This is why a system chart showing the CFM vs. SP is useful when designing a ductwork system. If you know how much CFM you have at a given static pressure, you can determine if a certain configuration will even work.

frequently asked questions

9


Q. Why is the Cfm of a cyclone slightly less than a regular dust collector of the same hp?A. The cyclone itself adds a slight restriction to the amount of air moved by the impeller. Said another way,

the cyclone has the same effect on performance as adding additional lengths of duct work. You see, the air travels around the inside of the cyclone many times before exiting to the filter. Plus just the fact there are pressure reductions when entering the cyclone adds a restriction. By that we mean, if the cyclone was a round cylinder with a pipe in and out, that would induce restrictions. Just as a 2-stage dust collector will have reduced CFM because of this, the same holds true for a cyclone.

Q. are they easy to empty?A. Our drums are sealed by the use of three quick release latches instead of the wrap around barrel-type

clamps. To disconnect from the cyclone for emptying, simply flip the 3 latches. Since the drum is equipped with casters just wheel the drum from underneath the cyclone for easy disposal. The lid of the drum remains attached to the cyclone by the flexible hose.

Q. are the filters easily damaged?A. Under normal conditions, the filters are not easily damaged, but accidents happen. Being hit by a board

or some other object will likely cause permanent and irreparable damage to the filter, which is why we protect ours within a cage. Ours is far less likely to be damaged than one without protection. Another way to damage a filter is using compressed air to clean it, which is why we developed a damage-free cleaning system.

Q. Just how well do they separate the dust from the air?A. Our cyclones will remove 99.9% of the particles between 0.2 and 2.0 microns. Larger particles are for all

intents and purposes 100% removed.

Q. are there maintenance costs?A. About the only maintenance costs are the plastic bags in the collection drum and on the filter bottom.They

can be reused or thrown away when full. Of course, it takes a long time to fill the bag on the filter. Thanks to our patented filter cleaning system, the cost of ownership will be less with our system verses one without a non-damaging filter cleaning system. The actual filter represents a surprising portion of the cost of the cyclone system and that is why we go to great lengths to prevent damage and extend the life of the filter. Our filters should last many years even under heavy use.

Q. how do i know when the collection drum is full?A. The collection drum needs to be checked periodically to avoid overfilling it. How quickly the drum will fill

is dependent upon the type of work being done at that time. While running a machine that produces more fine dust like a sander or saw it will take a long time to fill the drum. On the other hand, when planing soft lumber that produces curly shavings the drum may fill quite quickly. In the beginning you'll need to check your drum regularly as you learn how often it needs to be emptied.

Q. how long will the air filters last?A. This is where our cleaning system pays off with big savings for the owner. Many cyclone manufacturers'

filters must be cleaned by blowing them with compressed air. The use of compressed air not only blows fine dust throughout your shop, but is also damages the filter. Those who do not have our patented cleaning system argue that compressed air does not damage the filter nor does it create dust, but in our testing we found it did in fact damage the filter as well as created a dust cloud. Those same people who say compressed air won't damage the filter state in their instructions "Closer blasts may damage the filter." They say it won't damage the filter, then warn you it may, which is at best confusing. That is why we developed this cleaning system in the first place. With all that said, our filters will last for years and certainly last longer than those cleaned with compressed air.


10


Q. Do the filters plug up and do you have to clean them?A. Yes, the filters will eventually become clogged with fine dust and must be periodically cleaned as mentioned

above. Our patented cleaning system gently brushes away any built up dust on the inside of the filter, which then falls into the filter bag.

Q. Why do your cyclones look different than others?A. The most notable difference with ours, besides our square blower housing, is our exclusive inlet design. It

is longer, starts out round, then transitions into a rectangle and meets the cyclone at an angle, all of which improve performance.

Q. Do you really have a remote controlled magnetic switch? i have never seen one offered by anyone else.

A. Yes, we really do have a remote controlled magnetic switch with a built in programmable timer. When we discovered none were readily available, we put our engineers to work and designed one specifically for our purpose.

Q. other cyclone manufactures say you use a cheap asian made motor that will not last very long, is that true?

A. We cannot comment on why another manufacturer would make that claim, but maybe it's their attempt at explaining why their systems cost so much more than ours. Yes, we do use a motor made in Taiwan from the same manufacturer that builds most of our machinery motors. We buy tens of thousands of motors every year from this motor factory and are very confident in the quality. They are one of the highest quality manufacturers in Taiwan, using state of the art equipment. Further, our motors have been specifically designed for use in a cyclone under continuous, high torque use and are not an off-the-shelf product. We are not saying our motors are better than those made in the USA, but we are saying they are certainly comparable, designed for our cyclones and have additional features such as aluminum cooling fins.

Q. others say your filters are an inferior quality to theirs, is that true?A. Our filter material is made by a highly respected European manufacturer and is BIA certified. In other words,

that is not true and the BIA certification proves it.

Q. i already have a dust collector and duct work, but i would like to upgrade to one of your cyclones. Can i use my existing duct work?

A. Probably, but the design and layout of your duct work greatly affects how well it will perform. Long runs, long sections of flex hose or many elbows add restriction. Also it depends on the size of your main line and if it will allow enough airflow to maintain performance of the cyclone collector. To expect proper and efficient performance of the cyclone, you have to maintain a certain amount of airflow through it. If you have a 4" or smaller mainline, you may need to upgrade the size to the same or at least as close as possible to the inlet diameter of the cyclone or add additional trunk lines. Also, when using smaller machines with 2", 3" or 4" connections, it is a good idea to have a blast gate connected upstream of that smaller connection partially opened to ensure proper airflow to the cyclone.

Q. What's the difference between cyclones and two-stage dust collectors?A. All cyclones are two-stage dust collectors, but not all two-stage dust collectors are cyclones. Both drop

out heavier dust particles into a drum before passing finer particles through the fan and into a filter, but a cyclone is much more efficient at separating out more of the finer dust into the drum. Our cyclone filters are also pleated for efficient air exchange and are non-woven polyester fabric to capture the very finest dust. Many standard two-stage dust collectors only have bag filters that must be shaken out when they fill up.


11


Q. Can i use a standard garbage bag in the drum or under the filter instead of buying replacement bags from you?

A. We strongly recommend that you buy the replacement bags from us. Despite each manufacturer's claims of strength for holding garbage, standard garbage bags do not have the strength to withstand the air pressure produced by the cyclone fan and could blow apart, resulting in very fine dust being released into the air. Our replacement bags are inexpensive and are designed to withstand the high air pressure produced by the cyclone fan.

Q. how difficult is it to set up one of your cyclones?A. Our cyclones come with complete owner's manuals and set up is not difficult. With only 4 major components,

assembly time is relatively short. Most of the subassembly has already been done at the factory and the major components are only broken down for shipping. The optional stands will require additional assembly time. Each cyclone comes complete with fasteners and clamps; however, bolts for mounting the cyclone to the wall, if desired, are not included.

Q. others make a big deal out of their cyclones being galvanized. are yours galvanized?A. No, and here's why: First, galvanizing does not add much cost to a cyclone, but thicker steel does. We choose

to use thicker steel. Also, we use continuous welds in nearly all our seams. That's a lot of welding. Galvanizing doesn't weld very well and tends to burn off near the weld. Our thought was, it's either fully galvanized or it isn't, and once welded it's not. Rather than use galvanized steel that makes welding more difficult, we simply used thicker steel with all its advantages. Finally, our thoughts were that the abrasive action of the debris swirling inside the cyclone will wear away the galvanizing long before rust becomes a consideration.

Q. how difficult is it to wire one of your cyclones in my shop?A. First of all, you must ensure your shop has a spare circuit or the capacity in your service panel to add a circuit

that is capable of handling the amp requirements of the cyclone. We strongly recommend you hire a licensed electrician if adding a new circuit. Once the circuit requirements have been met, depending upon which cyclone is purchased, the cyclone can be hard wired to a wall mounted disconnect or connected to a plug-in device that is controlled by a wall mounted disconnect. Ensure that the amp rating of the outlet device and plug you use also match the amps for the circuit. The G0443, G0703 and G0703P 1-1/2 HP Cyclone come with a 110 plug, and can simply be plugged into a proper receptacle and circuit.

Q. Do i have to buy the stand?A. No, our cyclone is designed to mount to a wall, existing structure or a stand of your own making. Just make

sure whatever you mount it to can support the weight. And for those working in a basement or attached garage, remember that wall mounting may transmit noise into the house. G0440, G0443 and G0441 only. Stand included on other models.

Q. are your cyclones dual voltage?A. The G0703 and G0703P 1-1/2 HP cyclones are 110V/220V, pre-wired to 110V. You must purchase a conversion

kit to run them on 220V. The model for this is T25513. The G0443 1-1/2 HP cyclone is 110V/220V, pre-wired to 110V. You must purchase a 220V kit to convert it. The model for that is H7498. The G0440 2 HP, G0441 3 HP and G0442 5 HP are all 220V only. The G0601 5HP, G0637 7-1/2 HP, and G0638 10 HP are 220/440V, pre-wired to 220V. The 440V conversion kit for these models are: G440VG0601, G440VG0637 and G0440VG0638.

reducers & machine adapters

Reducers are used for reducing diameter of pipe and other applications, by attaching to conventional straight pipe on machine hoods and flexible hose. Adapters are for attaching metal ducting directly to the machines for a ridged pipe system set up.

floor sweepsThese individual floor sweeps close up tight and can take a lot of abuse. Add 3 or 4 around the shop and clean up will be faster and easier.

standard, "y", and Double branches

Standard branches are used for dropping down from above and splitting a main line. "Y" branches enable you to construct double runs and use multiple machine hook ups. Double branches are just the ticket for multiple machine set ups.

90o "t" branchesUsed mainly along wall set ups and around obstacles. "T" branches are the answer to problem spots.

Cyclone Dust Collection accessoriesstarter Kits

Our starter kits include everything you will need for a simple, single machine set up at one low price.

adjustable nipplesUse these slip fittings to make up any non-standard length less than 5'.

blast gatesThese individual blast gates can take the abuse of thousands of open and close cycles. Made specifically for production shops.
