Camfil Farr's GlidePack air filter housings provide leak-free (less than ½ of 1%, guaranteed) filter integrity. Available in two depths (13 and 25 inches) these housings include adapters to accommodate various types and depths of filters. Ribbed tracks allow filters to glide easily into the housing without binding, simplifying filter service, and are available in configurations from four high to six filters wide (8 feet by 12 feet). GlidePack MultiTracks are multiple-stage housings with adaptable tracks for prefilters, and final filters (including gas adsorbers). When upgrades are needed, housings are readily configurable in the field. Exclusive GlidePack features include a polypropylene fin seal filter gasket on each track that ensures filter-to-track air leakage of less than ½ of 1% across the filter; high-memory sponge neoprene door edge gaskets that prevent contaminants from migrating into (or out of) the housing; and poly sponge door gaskets that prevent filter bypass between the housings and filters. Construction is 16-gauge galvanized steel with out-turned standing flanges that mate perfectly with existing HVAC equipment and simplify installation. Moisture weeping paths on the housings make them weatherproof, for exterior installation without modification. There are two filter service doors, so filters can be serviced from either side of the housing; housing doors are engineered to be square to the housing for a tight filter seal. UV-resistant star-style handles assure a tight seal, and a new filter seal is established each time air filters are changed. Leak-free integrity is maintained throughout the housing’s long service life.
