Bulk Media & Pads

Permaire Rolls and Pads

Permaire is a unique completely synthetic, self-supporting and washable media.

Permaire pads cut to the proper dimensions is actually a complete filter ready

to install. With nothing more than Permaire and a hefty pair of scissors or a

razor knife, replace almost any size 1/2”, 1” or 2” framed panel filter.

Permaire filters are passive electrostatic type products. Air running over the

maze of fibers creates an electrostatic charge to catch and hold airborne

contaminants. Dirt loads throughout the filter’s depth holding a lot more dust

than other filters before requiring changing or cleaning.

Hogs Hair Rolls

Hogs Hair is a unique type of filtration media consisting of natural organic

fibers. Only available in rolls, its specifications meet the above noted Permaire

Rolls. Contact your account specialist about the natural Hogs Hair media – Part

Bulk Media and Pads

Spun Glass

Spun glass is a rugged industry standard, known for low resistance while

providing excellent arrestance and high dust holding capacity. They are designed to trap dirt throughout their

thickness. A resinous bonding agent in the media increases rigidity and resistance to compression so the filter

will not collapse in the airstream. Flashpoint is 325 degrees Fahrenheit on the treated adhesive.

7/8” Blue Production Glass (Models GMxx) Nominal 7/8” adhesive-treated spun glass. For residential

or light industrial and commercial air filtration. Commonly used for 1” depth disposable panel air filter

production and for pad and frame systems.

Blue on White Industrial Glass (Models Gxxx) Nominal 1” and 2” adhesive treated spun glass. For industrial

and commercial air filtration with fairly heavy dirt loads. Commonly used for pad and frame systems and

hammock rolls. Tinted blue on the air entering side.

Series 330G PA Green Paint Arrestor Glass (Models 330G-xxx) Model 330 Green glass is a 2.5” economical

dry spun glass media for prep station and paint spray booth applications.

Series 331Y PA Yellow Paint Arrestor Glass (Models 331Y-xxx) Model 331 is a heavy duty version of dry spun

glass for prep station and paint spray booth applications.

4” “Railroad” Glass Nominal 4 “ spun glass for air filtration in railroad diesel engines. Manufactured

according to customer specifications.

3/8” A/C Media (Models ACxx) Nominal 3/8“ untreated (no adhesive) blue on white spun glass. Makes rigid

pads for use in room air conditioning units.

Polyester Synthetic Fiber

Polyester Synthetic Fiber (PSF) media is extremely resilient and will withstand direct moisture. In many

cases, a PSF media is the ideal alternative to spun glass. It makes an excellent prefilter for high efficiency

filters and offers a high arrestance and dust holding capacity.

PSF 5DT, 1DT, 2DT (Models 5Txx, 1Txx and 2Txx) Dry, untreated psf media in nominal 1/2“, 1“ and 2“ thick-

ness for a wide range of filtration applications. White and blue with blue on the air exit side.
