HeavyDuty™ Panel Filters

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 that 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.

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.
