The Camfil Farr 4P Glide/Pack® is a single-stage filter housing designed to hold a 2", 4", or 6" deep high-efficiency ASHRAE grade filters.
The Camfil Farr Glide/Pack® series of side-access filter housings have set the standard for integrity for over 20 years. With its integral universal filter holding frame virtually all of the air seen by the filter will be treated by the filter. Each Camfil Farr 4P Glide/Pack includes:- 16-gauge galvanized steel construction with pre-drilled standing flanges to mate to existing HVAC equipment. All components are weatherproof for interior or exterior installation.
- Dual-access doors for filter service from either side of the unit. The doors swing-open and are engineered to be square to the housing flange. UV resistant star-style handles assure a tight seal each time the access doors are opened and closed.
- High-memory sponge neoprene door gaskets to ensure door-to-filter seal (less than one half of 1% housing to ambient leakage).
- A poly sponge door gasket to assure a proper door-to-filter seal.
- A polypropylene fin seal on the filter track to eliminate filter air bypass (less than 1/2 of 1% leakage across the filter assembly at rated airflow).
- An aluminum mounting track for the universal holding frame allowing for the application of any nominal 1-inch deep, 2-inch deep, 4-inch deep, or 6-inch deep air filter.
