PerfectPleat - Strength and Durability

Creating the 4” PerfectPleat presented unique challenges. Once again, AAF engineers drew upon years of experience in filter manufacturing to produce a 4” filter worthy of the name PerfectPleat. Each model of the 4” PerfectPleat places a DuraFlex media pack inside of a two piece frame. Straps are added to the air-entering side of the filter to help maintain pleat spacing, while specially designed pleat spacers are inserted in multiple rows on the air-leaving side. The pleat spacers also assist in keeping the pleats open during use, maximizing filter life. The two-piece frame is then assembled around the rigid media pack and is bonded at all contact points with adhesives that ensure resistance to moisture. The result is fit and finish unlike anything available in a 4” pleat coupled with excellent strength and durability.
