Glasfloss GDS_12X20X1 Fiberglass Panel Air Filter 12x20x1

Product Description

The GLASFLOSS GDS_12X20X1 is a disposable fiberglass panel air filter built for commercial, industrial, and residential HVAC applications. It measures 12 inches wide by 20 inches tall by 1 inch deep and delivers a rated airflow of 300 FPM with an initial resistance of 0.09 inches WC and a final resistance of 0.50 inches WC. The filter uses progressively dense fiberglass media thermally bonded to a heavy-duty one-piece craft-board frame. The double-strut frame construction provides a 10 percent greater open media area than traditional metal grill designs, improving dust-holding capacity while simplifying disposal. HVAC technicians and facility maintenance crews install this filter across a wide range of air-handling equipment.

This filter suits commercial rooftop units, industrial air handlers, and residential forced-air systems where a low-cost, high-efficiency disposable panel filter is appropriate. The craft-board frame eliminates sharp edges, making changeouts faster and safer than metal-frame alternatives. The design also reduces carton weight, which simplifies storage and logistics on multi-unit service routes. It is rated to 180 degrees F, making it suitable for higher-temperature return-air applications common in commercial and light industrial environments.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always shut down the air-handling unit and lock out power before removing or installing a filter. Confirm airflow direction markings on the frame align with system airflow before seating the filter. Inspect the filter housing for bypass gaps and correct any frame distortion before returning the unit to service.
