Sturdy, Economical, Disposable Panel Filters with Woven Glass Retainer Designed for general air filtration applications with light to medium dust loading conditions, AAF HeavyDuty disposable panel filters are engineered for sturdy, economical performance and ease of use. Available in a wide range of sizes and two thickness configurations, these filters are used in all types of HVAC systems to protect the coils from dirt and as prefilters to extend the life of higher efficiency filters. HeavyDuty filters offer superior strength and durability in any application. Disposable Panel Filters With Glass Retainer High Arrestance HeavyDuty filters are constructed with heavy duty, premium grade fiberglass media, and have a skin on the air-entering and air-leaving sides. A woven glass retainer is bonded to the clean air side of each filter. Premium grade fiberglass has more fibers to ensure HeavyDuty media offers higher arrestance and cleans the air better than competitive filters. Premium grade fiberglass also offers higher dust holding capacity which means longer service life and lower operating costs. Sturdy Construction, Longer Filter Life Compression Resistant Media The woven glass retainer and skin provide excellent support for the fiberglass. The heavier construction of the fiberglass allows a better adhesive bond with the retainer. Compression resistant glass fibers decrease media pad deterioration allowing a slower rise in resistance as the filter collects dirt particles. A slower rise in resistance extends the life of the filter. Frame Strength A continuous adhesive bond between the media pad and recycled kraft frame maximizes construction strength to reduce handling damage and maintain structured integrity in operation. 40x magnification shows the spun fiberglass skin of the HeavyDuty ™ filter pad. Woven Glass Retainers The woven glass retainers used on the HeavyDuty filters add strength to the filter assembly while maintaining a metal free product. The HeavyDuty panel filters are safer to handle than filters made with "bottlecap" retainers that break easily and have sharp points and edges that can cut fingers and hands. The bond strength of the glass retainer to the frame is also superior.
