PermaFlo Blue Rigid Polyester Filter Roll - 1" or 1/2" Thick - Choose Width

Non-woven polyester is a synthetic air filter media. The fibers are randomly dispersed in all directions through an air laid web. This forms a uniform media of high strength, rigidity and durability. A high volume of contaminants can be trapped within the complete depth of fiber, and the media can be installed without a metal frame.

PermaFlo is a fantastic alternative to hogs hair filters and a high performance, and an economical alternative to disposable pleated air filters, with lower initial resistance to air flow.

A Better Mist Eliminator – rigid nonwoven polyester media is more effective in collecting water and mist. The media keeps water out of equipment because the types of mist (liquid and air) cling to the fiber material, without absorbing moisture or sagging in moist environments. Independent test results for water penetration using UL-50 rain yielded “no water droplets penetrating to the inside of the testing chamber. No moisture on the back side surface of the expanded galvanized protective screen.”
