VariPak filters are designed for reliability and long service life under difficult operating conditions including high velocity and turbulence. The rigid media pack is not affected by changes in air flow or repeated fan shutdown.
In applications where the use of fiberglass is restricted, Model S is an excellent choice. The wide range of efficiencies and rigid cell construction make this an ideal product for upgrading existing systems. The microfine synthetic media offers lower resistance and is unaffected by high humidity or moisture.
