Blowers Exhausters

Operating principleThe regenerative blower or exhauster increases the pressure of the aspirated gas by the creation, in the peripheral toroidal channel, of a series of vortexes caused by the centrifugal thrust of the impeller. While the impeller is rotating, the vanes force the gas forward and, because of the centrifugal thrust, outwards, producing a helical motion.During this motion, the gas is recompressed repeatedly with a consequent linear pressure increase along the length of the channel.

Applications and advantagesRegenerative blowers are suitable for all those applications requiring considerably higher pressures than that which can be achieved using centrifugal fans. Regenerative exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan, but not as high as to require the use of a vacuum pump.The rotating parts are not in contact with the casing. There is therefore no friction during operation and thus no internal lubrication is necessary. The machine therefore remains uncontaminated and completely oil-free.The other main advantages of using regenerative machines are:• easy installation;• low noise level;• no vibration and therefore complete dynamic stability;• pulsation free discharge; • minimal maintenance.

Technical and constructional features• Casings and impellers are made of aluminium alloy.

• The standard machines for air are manufactured in the so-called “CLOSE COUPLED”version; i.e. a flange mounted electric motor is bolted to the machine casing. The impeller, which is dynamically balanced, is fitted directly onto the motor shaft extension.

• The two-pole electric motors, designed for continuous operation, are available in three phase for all the powers shown in the catalogue and in single phase up to 2.65 kW. They are manufactured according to IEC and/or CSA Standards with the following features for the customary construction:

- for machines without HS suffixdegree of protection: - IP 55insulation class: - Fline voltages at 60 Hz:- three phase motors: 265 VΔ / 460 V for powers up to 3.6 kW 460 VΔ / 795 V for powers ≥ 4.6 kW - single phase motors: 240 Vallowed tolerance on supply voltage: ± 5%

- for machines with HS suffixdegree of protection: - IP54insulation class: - Fline voltages at 60 Hz:- three phase motors: 208~275 VΔ / 380~480 V for powers up to 4.6 kW 380~480 VΔ / 660~720 V for powers > 4.6 kW An exception is the customary construction of the CL 80-Z HS 4.6 kW motor for which the line voltage has to be 380~480 VΔ / 660~720 V- single phase motors: 104~127 V / 208~254 V

• The machines meet the requirements of the European Directives 2006/42 (Machines), 2006/95 (Low Voltage), 2004/108 (Electromagnetic Compatibility) and of the applicable harmonised Standards.

• For the handling of gases other than air, e.g. steam, industrial gases and mixtures of explosive gases, special gas tight units can be manufactured.

In particular, for mixtures of combustible gases, such as natural and biological gases, a range of machines, featuring a specific MAPRO® manufacturing technology, synthetically outlined at pages from 18 to 21, has been designed. This technology is identified by the trademark:

In the case of corrosive gases, all the internal parts can be treated or lined with protective coatings.

AccessoriesA complete range of accessories, synthetically outlined at page 16 and 17, is available for all machines.

AccessoriesFor all regenerative blowers and exhausters, a complete range of accessories is available. Main accessories are:- cartridge type filters for blowers - in-line filters for exhausters- pressure relief valves for blowers - vacuum relief valves for exhausters- non return valves- flexible hoses - acoustic enclosures.

For proper use, a blower is to be equipped at least with inlet filter and pressure relief valve; an exhauster with inlet inline filter and vacuum relief valve.For more and technical details on the accessories shown below, please contact MAPRO® Sales Department.

Pressure relief valves for blowersMAPRO® pressure relief valves are designed to protect blowers from over pressurization. When a too high pressure is achieved in the outlet pipe, the valve opens and discharges the air to ambience. The valves are commonly fitted in an offtake at the blower outlet, but for some machines, listed on the table below, they are directly integrated in the blower casing, as shown in the picture beside the table.

Vacuum relief valves for exhaustersMAPRO® vacuum relief valves are designed to protect exhausters from excess vacuum during operation. The valve is fitted in an offtake at the exhauster inlet. When an excess vacuum is achieved in the inlet pipe, the valve opens and fresh air is sucked from ambience into the machine. Depending on where the exhauster is installed, the vacuum relief valve can be fitted with a silencer, as well as a filter, to prevent ingress of dust into the machine.

Filters for exhaustersInline filters are typically used for vacuum applications to prevent dust and any abrasive particle from entering the exhauster. They consist of a metal housing with a metal cover retained by toggle clamps for an easy internal inspection and service. The filter element can be proposed made with pleated paper impregnated with thermoset resin or made with polyester for humid applications. Antistatic polyester filter elements are available for installation in hazardous areas.

Filters for blowersInlet filters are typically used for pressure applications to prevent dust and other particles from entering the blower. They consist of a filter cartridge protected by an aluminium hood. The filter element can be proposed made with pleated paper impregnated with thermoset resin or made with polyester for humid applications. Antistatic polyester filter elements are available for installation in hazardous areas.

Special filters, e.g. for heavy duty applications due to strong presence of dust, are available on request.

Non return valvesThe purpose of a non return valve installation is to prevent and protect the blower or exhauster against the consequences of reverse air flow in all the applications where this could be possible further to the machine automatic shutdown for safety devices intervention.The non return valve provides high integrity first-line defense in the event of unwanted reverse flow. It is immediately responsive and fast acting in its closure, thereby maximizing protection to prevent or minimize the adverse effect of any back-flow.

Flexible hosesThe purpose of the flexible hoses installed between the blower or exhauster and the discharge or inlet pipeline is to avoid that the direct connections of the pipes to the threaded outlet and/or inlet port could cause unwanted tension or load on flanges and casing of the machine. This could cause breaking of flanges or casing or casing distortions with consequent seizure of the impeller.Flexible hoses made of various materials and for different pressures and temperatures are available, depending on the foreseen operating conditions.

Acoustic enclosuresAcoustic enclosures are available for each type of machine. They are made up from indepen-dently removable acoustic panels externally clad with galvanized sheet steel. The panels are fixed together with externally mounted clamps, galvanized as well. On request, clamps in stainless steel could be supplied. Sound pressure levels are reduced by about 12 dB(A). The acoustic enclosures, for all side channel exhausters and for blowers with motor power above 4 kW, are fitted with an electrically operated ventilation fan with sound deadened duct. Please contact our Sales Department for detailed information and for the dimensions of the acoustic enclosures.

REGENERATIVE BLOWERS FOR COMBUSTIBLE GASES

Blowers for biogas, natural gas or combustible gases, in conformity to the 94/9/EC European Directive (ATEX), for Zones 1 and 2, or, especially for US and Canada, in conformity to the requirements of Class I hazardous locations

Features of constructionTo extract or compress combustible gases, such as biological gas or natural gas, a complete range of gas-tight regenerative blowers has been designed, featuring a specific MAPRO® manufacturing technology, identified by the trademark:

This technology, whose main construction features are listed below, is applied also to the blowers fitted with NEMA motors in conformity to the requirements of Class I hazardous locations in the US and Canada. Only the so-called “CLOSE COUPLED” version (see below) is not available with NEMA motors.

The MAPRO® regenerative blowers have been designed in order to fall within the Equipment-Group II as defined by the 94/9/EC Directive (ATEX), Category 2 both for the surrounding area conditions and for the internals of the machines.They are therefore gas-tight blowers, with the following construction features:•casing and impellers made completely of spark proof aluminium alloy•casing impregnated with Loctite•casing halves sealed•shaft sealing by special double-lip seals which do not require

lubrication•two-pole, type of protection “d”, flameproof electric motors, with

specific marking Ex II 2 G, additional marking Ex-d IIB T3.The simplest solution for the manufacturing of the machines is the so-called “CLOSE COUPLED” version (not available with NEMA motors) – i.e., a flange mounted electric motor is bolted to the blower casing; the impeller, which is dynamically balanced, is fitted directly onto the motor shaft extension.Furthermore, machines with their own shaft and bearings and coupled to the electric motors via flexible shaft couplings or belt drives can be proposed.In these cases, the safety drive guards are made from spark-free material.

If the area surrounding the equipment is classified as Zone 2, where, for the Group II, Category 3 equipments are accepted, the machine could be equipped with the type of protection “n” non-sparking motor, with specific marking Ex II 3 G, additional marking Ex-nA II T3.In some particular cases, all the internal aluminium parts wetted by gas can be treated with anodic oxidation; the machine can be supplied with its own shaft and external bearing housings, so that the bearings are completely isolated from the gas handled; and it is also possible to fit lip seals in pairs, with a barrier fluid in between.

AdvantagesThe main advantages of using regenerative machines are:•easy installation•low noise level•no vibration•pulsation free gas flow•minimal maintenance.Moreover no internal lubricationis necessary, and therefore the gasmoving through the machine remains uncontaminated and completely oil-free.

The most common fields of application•Landfill biogas recovery to feed torch, burner or gas engine•Tank, plant or contaminated soil gas recovery to feed torch or burner•Extraction of biogas from gasometer, natural gas from pipeline or gasometer, and burner or gas engine feeding.

Machines with gas recirculation (by-pass)When the gas has to feed a burner or when a variable gas flow is required, a “compact by-pass”, directly bolted to the machine and connecting outlet and inlet ports, is a simple and effective solution. A suitable overpressure relief valve is fitted inside the “compact by-pass”.When the gas demand decreases, the outlet pressure increases, and, when the set pressure is reached, the overpressure relief valve starts to open and by-passes excess gas back to the blower suction. In case of low differential pressure, usually the “compact by-pass” is capable of handling the full capacity of the blower and thus the machine can continue to run even if the downstream gas demand is reduced to zero.

For higher differential pressures, where the use of a “compact by-pass” is not allowed because of the high temperature increase when the full capacity of the blower is by-passed back to the suction, the machine can be supplied with the overpressure relief valve fitted on an offtake at the outlet side.In that case the flanged valve discharge could be piped-back to the blower suction through a by-pass pipe long enough to allow for the sufficient gas cooling.On request, we can also offer machines equipped with a suitable gas cooler at the blower outlet, with overpressure relief valve fitted in an offtake at the cooler outlet, and with the complete “by-pass pipe” back to the blower suction side.We can also offer automatic flow rate adjustment by means of pneumatic or electrically operated flow control valve, fitted in the by-pass line and controlled via the client process parameter “discharge gas pressure”.

ds of application

Some installation

Machines controlled via frequency inverterIf the gas demand varies in time (such as for burner or engine feeding), we can supply blowers equipped with a motor intended for control via frequency inverter. The rpm range of the blower (and therefore the output frequency of the frequency inverter) can be adjusted according to the foreseen operating conditions, and in particular to the expected differential pressure between blower discharge and suction.The speed of rotation of the motor shall be controlled via the “discharge gas pressure” process parameter.

AccessoriesA complete range of accessories is available, including the following:•gas-tight filters•stainless steel flanged flexible connection bellows•non return valves•pressure gauges and thermometers•explosion-proof pressure switches and temperature switches•intrinsically-safe pressure and temperature transducers•manual and automatic cut-off valves•acoustic enclosures.
