Pro-source PRO11739 Air Filter Media Pad 20x25x1 Merv 7

Product Description

The PRO-SOURCE PRO11739 is a polyester air filter media pad rated MERV 7, designed for use in commercial and residential air handling equipment as a pre-filter or primary filtration layer. Measuring 20 x 25 x 1 inches and weighing 0.05 pounds, this pad captures airborne particulates at 25 percent particle capture efficiency and 85 percent arrestance efficiency. It handles airflow up to 1,042 CFM at a maximum face velocity of 300 feet per minute (FPM) and withstands temperatures up to 180 degrees F. The dry tackifier media construction holds captured particles without adhesive migration into the airstream. HVAC technicians and sheet metal contractors use these pads as cut-to-fit or drop-in filtration media in a wide range of air handling units.

This media pad is suited for light commercial and residential HVAC installations where a cost-effective, low-restriction filtration stage is required. Common applications include air handling units, fan coil units, make-up air units, and ceiling cassettes where a flat pad filter is the specified format. The 0.14 inches water gauge (wg) initial resistance keeps system static pressure low, making it appropriate for lower-static fan systems. At a final resistance of 1.0 inch wg, the pad has reached end-of-service life and should be replaced. Its polyester construction with dry tackifier media is compatible with dry filtration environments and standard supply-air systems.

Key Features

• MERV 7 rating with 25 percent particle capture efficiency and 85 percent arrestance efficiency
• Low initial resistance of 0.14 inches wg supports low-static fan systems
• Rated for airflow up to 1,042 CFM at a maximum face velocity of 300 FPM
• Withstands operating temperatures up to 180 degrees F
• Dry tackifier polyester media construction — no wet adhesive migration
• UL Class 2 listed filtration media

Compatibility

Rated for use with any air handling unit. This pad format is a standard drop-in or cut-to-fit replacement for flat media filter pads in residential and light commercial HVAC equipment.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Power down the air handling unit at the disconnect before accessing the filter section. Ensure the pad is seated flush against the filter rack or holding frame with no bypass gaps around the perimeter. Inspect and replace when final resistance reaches 1.0 inch wg or per the system maintenance schedule.
