The result is a filter of consistently high quality at a competitive price. Construction This disposable heating and air conditioning filter has a one-piece chipboard frame. This feature eliminates the problems associated with a four-piece frame, such as broken corners and exposed metal edges. The Pinch Frame filter utilizes a heat seal to bond the frame to the filter media and metal support grid. This process permits the use of a single metal grid on the air exit side only, thus maximizing filter face area and extending service life. The media is made of 100% nonwoven polyester synthetic fibers chemically bonded with a fire retardant resin. Because of the synthetic nature of the fiber, the media is extremely resistant to moisture and other environmental extremes. Physical Data Frame: One-piece chipboard Media: Dry resinated polyester Support Grid: Perforated metal on air-exit side Sealant: Hot-melt resin Nominal Thickness: 1” Flammability: UL 900 Class 2 Important Features • One-piece chipboard frame prevents broken corners and exposed metal. • Heat-sealed frame provides unusual strength and serviceability. • A metal grid on the air-exit side assures more open face area and longer service life. • Resinated polyester media provides resistance to moisture. • Filters are UL 900 Class 2 listed. Note: Manufactured on the West Coast Only.
