The Flanders Pinch Frame Series 11655.011620 Disposable Filter is designed for use in light commercial and industrial heating and air conditioning applications, as well as residential furnace applications. These 16" x 20'' x 1" filters are constructed with moisture-resistant polyester synthetic fibers bonded by fire-retardant resin. The frame and media are heat-sealed to maximize filter face area, extending the life of your filter. They are UL 900 class 2 listed for flammability, so when clean, the filters did not flame or emit excessive sparks when tested.
One-Piece Moisture-Resistant Frame
Media pads and support grilles are glued to the inside perimeter of the frame. This one-piece construction results in exceptional strength and rigidity.
UL 900 Class 2 Listed
Filters are flame resistant. When clean, air filters do not produce flames or extensive sparks when subjected to a flame exposure test.
The filter removes 60-80% of synthetic dust from the airstream.
Heat-Sealed Media and Frame
The media and frame are heat-sealed, permitting use of a single metal grid on the air exit side only which maximizes surface area.
