A unique package consisting of guard, filter media
and retainer. The guard and retainer are manufactured with UL rated
94V-0 material. The filter media is made of polyurethane foam (30PPI)
and allows free passage of air with minimum air resistance and pressure
drop. A major feature of this assembly is that when the filter media
requires maintenance you simply remove the snap-fit retainer to clean
or replace the filter, leaving the guard attached to the fan. This
assures protection to the fan blade and eliminates damage to the fan
during cleaning. Available for 1.5" (40mm), 2.5" (60mm), 3.125" (80mm),
3.625" (92mm) and 4.5" (120mm) fan sizes. Meets UL 0.250" (6,35mm)
plug gauge test.
