Perma-Flo® Polyester Rigid Pad Air Filter
Perma-Flo® polyester air filtration media is a fantastic alternative to Hogs Hair media and a high performance, economical alternative to disposable air filters. Model PFLO is available in a 1/2" or 1" thick rigid blue polyester media that is self supporting and needs no frame. The polyester fiber does not flake, shed or have sharp edges. The fibers are unaffected by moisture, and clean easily with water for long term use. Humidity resistant, Perma-Flo will not absorb moisture or sag in moist environments. Media is easily cleaned with water for long term use. It's bi-directional (unlike hogs hair that must be installed correctly or face loading rapidly occurs) air flow insures that it can't be installed wrong. Perma-Flo offers a lower initial resistance to airflow than pleated filters. Media can be cut with scissors eliminating air by-pass. Perma-Flo has a bi-directional air flow. This product is available in 25" x 48', 25" x 36' or 30" x 36' service rolls, as well as, standard and custom sized pads.
