HeavyDuty Fiberglass Filter
HeavyDuty filters offer superior strength and durability in any application. They are used in all types of HVAC systems to protect coils from dirt and as prefilters to extend the life of higher efficiency filters. HeavyDuty filters are constructed with heavy duty, premium grade fiberglass. A woven mesh retainer is added to the air leaving side on all standard sizes for additional support. Designed for commercial and residential air filtration systems. Available in both 1" and 2" depths.
PREMIUM PERFORMANCE WITH EXTRA STRENGTH
Each HeavyDuty Fiberglass Panel Filter is assembled with continuous beads of hotmelt adhesive applied to the frame's inside perimeter on both the airentering and airleaving sides to firmly secure the pad/retainer assembly to the frame. Each HeavyDuty Fiberglass Panel Filter contains AAF©made fiberglass media ensuring that you receive the filtration efficiency you expect.
• High Arrestance HeavyDuty filters are constructed with AAF manufactured premium grade fiberglass media. More fibers ensure HeavyDuty media have higher arrestance and clean the air better than competitive filters.
• High Dust Holding Capacity The media is coated with a light adhesive to increase the amount of dirt the filters can hold. Higher dust holding capacity means longer service life and lower operating costs.

DESIGNED FOR EASY HANDLING AND DISPOSAL The chipboard filter frame, free of sharp edges, makes the panel easy to install and remove. After removal, the filter can be safely folded for compact disposal.
