Pro-source PRO18331 Bag Air Filter Merv 13 22x12x24

Product Description

The PRO-SOURCE PRO18331 is a synthetic media bag filter rated MERV 13, designed for commercial and industrial HVAC air-handling units and makeup air systems. With a nominal size of 22 inches deep by 12 inches wide by 24 inches high and a 3-pocket configuration, this filter delivers 80 to 85 percent particle capture efficiency across a wide range of airborne contaminants including fine dust, pollen, mold spores, and combustion particles. The galvanized steel integrated frame maintains bag geometry under operating airflow, and the synthetic media handles temperatures up to 150 degrees F. Rated for airflows up to 1,000 CFM at a maximum face velocity of 500 FPM, it suits demanding mechanical systems where MERV 13 filtration is specified by code or design.

This filter is used in commercial rooftop units, air-handling units, and built-up systems where extended-surface bag filtration is required. It is a common specification in schools, hospitals, office buildings, and light industrial facilities that require intermediate-efficiency particulate control. Licensed HVAC technicians and building mechanical contractors typically handle installation during scheduled filter maintenance or system commissioning. The 12-inch-wide by 24-inch-high nominal face dimensions fit standard side-access filter housings designed for that opening size.

Key Features

• 3-pocket synthetic media bag for extended surface area and lower pressure drop
• Galvanized steel integrated frame holds bag shape at rated airflow
• Maximum working temperature of 150 degrees F for high-load mechanical rooms
• Rated for up to 1,000 CFM and 500 FPM face velocity
• UL 900 listed construction

Compatibility

Designed as an OEM-style replacement bag filter for commercial air-handling units and filter housings accepting a 12-inch-wide by 24-inch-high nominal bag filter with a 22-inch depth.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Always shut down the air-handling unit and confirm airflow has stopped before opening the filter access section. Verify the actual filter dimensions of 11.375 inches wide by 23.375 inches high by 22 inches deep against the housing track clearances before inserting to avoid bypass leakage. Installed filters should be inspected per the maintenance schedule established by the system designer or per local mechanical code requirements.
