Customers with commercial

air conditioning units, such as

shown below, are most adversely

affected by inferior housings

supplied by AHU manufacturers,

for reasons we‘ll explain in the

following pages.

BaCKGrOUNDSeveral years ago, air handling unit (AHU) manufacturers decided to make filter housings part of their units. This meant they sometimes dictated what filters could be used in their equipment.

If an engineer specified a certain type of air filter, the AHU manufacturer would source the lowest cost, lowest performing version that met the general intent. There was another, bigger, problem as well. The housings and frames made by the AHU companies were really just “frames and housings,” that is, simple metal extrusions made to hold filters. They were not made by companies who understood filtration, or the way housings must be designed in order to do the two things that are important to users: • prevent air bypass • conserve energy by making sure

treated air is not lost through leakage.

Recently, AHU manufacturers made problems even worse for end users

when they reduced the depth of their filter housings to reduce overall system cost. Now, users who buy their AHUs with filter housings included have even fewer options, and those “options” don’t include 5-Star energy saving and long life filters. Customers in health care, pharma and other industries asked Camfil farr to develop a filter housing solution that would put all decisions regarding filtration back where they belong: with engineers and end users. We welcomed this opportunity. For more than 80 years, Camfil Farr has been the world leader in the development of sustainable best-in-class air filtration products and services.

Our expertise with clean rooms, hazardous materials containment, pharmaceutical manufacturing and other challenging environments made us uniquely qualified to develop and manufacture housing solutions that optimize the performance of any filter, while preventing bypass which compromises air quality, and the wasted energy that drives up utility costs.

No air filter BypassCamfil Farr housings are guaranteed to have less than 1% air bypass

so all of the air moving through the housing is treated by the filters.

GlidePack is an engineered housing solution that ensures all air moving through the system is treated by the air filters, and bypass is prevented. This weatherproof, side-access housing also prevents leakage.

Standard AHU housings can leak in two directions: from inside the housing to the outside, and from the outside to the inside. As a result, a filter cannot deliver its rated efficiency. A separate issue related to leakage is the cost of cooled and heated air: when treated air is lost to leakage, utility costs are unnecessarily high. • GlidePack multi-Track 25 is a multi-stage filter housing with

adjustable tracks for multiple filter configurations. Adaptable tracks accommodate many prefiltration options, as well as secondary filtration such as adsorbers and final filtration. This housing is also field-configurable for future filter upgrades. Slide modifiers accom-modate a 1, 2, or 4" deep prefilter, a 2 or 4" intermediate particulate or carbon filter, and a 6" or 12" rigid or pocket final filter.

• GlidePack multi-Track 13 is a short-depth multi-stage air filter housing with adjustable tracks for multiple housing configurations.

• GlidePack UniTrack is a single-stage filter housing. A 1" filter track holds short-depth bag filters or 6" box filters in the GlidePack Uni-Track 13, or longer bags or 12" box filters in the UniTrack 25. Tracks have ribbed surfaces to ensure filters slide easily across the tracks in housing configurations of 4 high to 6 wide.

All GlidePack housings have replaceable fin seal polypropylene final filter gasketing that ensures a secure filter-to-track seal of less than half of one percent across the filter at 3.0" w.g.

Out-turned flanges mate with all HVAC equipment. Dual access galvanized steel doors allow filter service from either side of the unit. High-memory sponge neoprene door edge gaskets assure integrity of housing to ambient leakage of less than 1%. Stainless steel and high pressure (to 8.0" w.g.) housings are available.

freedom in filter ChoiceThe customers who asked Camfil Farr to develop a quality filter housing had numerous objections to the housings supplied by the equipment companies.

The #1 complaint was that buyers were “locked-in” to the filters – and filter configurations the equipment maker wanted them to buy – now, and in the future. If the customer accepted the housing supplied by the AHU manufacturer, he paid a higher energy cost and would have inferior filtration for the life of the AHU.

If the user’s requirements changed, or if the user simply wanted a different filtration so-lution than the AHU maker had provided for, the only resource was costly customization, or replacement.

Customers also realized that filter tech- nology evolves continuously. What was purchased 10 and even 5 years ago is vastly different from what is preferred today. locking-in decisions regarding filtration almost never makes sense from the customer’s standpoint. The GlidePack housings developed by Camfil Farr answer these concerns. They are universal, and they give engineers,

contractors and customers virtually unlimited choices in terms of what filters are used, and how they’re configured.

Their adaptable tracks provide an economic advantage for contractors, because they accommodate the rough-in filters used for new construction, as well as the final filters. And because they prevent bypass, they assure that all filters perform to their greatest potential.

filter choice is directly related to on-going energy cost as well. The filters provided by the AHU manufacturers are typically less than 12" depth and thus by design, consume more energy than Camfil Farr 5-Star rated air filters.

GlidePack housings are engineered to accommodate the best-performing air filter products in multiple stages, so that fan-related energy use is low at the time of installation, and remains low throughout the filters’ service life. Filters from all

manufacturers are fully compatible with GlidePack housings.

Sustainability AHU companies regard air filters as a commodity, and source them solely on price. Not life cycle cost, but straight purchase cost. This is not in the best interest of end users who will experience higher-than-necessary maintenance and operational costs throughout the systems’ life because of this choice. Camfil farr 5-Star* filters have the lowest average pressure drop and therefore the lowest energy use rate. They also have the longest service life—a major factor in minimizing labor and disposal costs. And they maintain their rated efficiency (MERV and MERV-A) the entire time they are in use. They are, for many companies, an important part of an overall effort to meet corporate goals for waste minimization and sustainability.

Another common complaint from customers about AHU company housings is that as many as 5 different filter sizes are used in a single AHU. So, in addition to limiting filter choices, the user is forced to buy several filters in sizes that fit that housing.

Most companies today are trying to streamline the number of products they have to buy and inventory, so standardizing filter size is an important step toward that goal.

It is also worth noting that non-standard filter sizes often perform at lower levels, with reduced life and higher average pressure drop than filters that were specifically selected for that facility and application.

flexibility for

the future GlidePack housings are engineered with high quality tracks and sealing technology that insures against leakage and optimizes both air quality and equipment protection. Multi-Track housings accommodate up to 3 filters in a series, where both contaminant and gas phase filtration is needed.

Tracks can be altered quickly, without tools, to accommodate various air filter depth and design configurations. So, in the future, when higher perfor-mance products are available, a Camfil Farr housing will adapt to the new technology without modifications.

The one-time investment in quality GlidePack housings will last (or out-last) the AHU system.
