20x20x4 Nominal Air Filter Pad Holding Frame


20 X 20 X 4 Nominal


The HP Series pad holding frame is designed to replace disposable air filters in residential, commercial and industrial HVAC applications with an economical, replaceable pad holding system. Regardless of the filtering medium, or combination of media, the HP Series frame is built for the safe and rapid change of the filter media and can last for the life of the original HVAC equipment. The frame is available with a wire gate for added pad security. Select from three different metal alloys to obtain the best frame for your application.

The HP Series uses a metal frame to enclose a metal support grid. The grid is made of expanded metal and is permanently attached to the inside flange on the air exit side. It fits firmly inside the frame giving the HP Series exceptional strength and durability. As an option, a hinged wire gate may be installed on the air entrance side of the frame. The frame is made with mitered corners and is secured with pop-rivet(s).
