The PRO-SOURCE PRO12448 is a 4-pocket bag air filter rated MERV 13, designed for commercial and industrial HVAC air handling systems where higher filtration efficiency is required. The fiberglass media delivers 80 to 85 percent particle capture efficiency, capturing fine dust, mold spores, and other airborne particulates before they reach downstream coils or occupied spaces. The galvanized steel integrated frame holds its shape under sustained airflow up to 500 feet per minute and withstands operating temperatures up to 180 degrees F. Licensed HVAC technicians and building engineers typically specify this filter in commercial rooftop units, air handling units, and central station fans.
This bag filter fits nominal 12 inches wide by 24 inches high by 29 inches deep filter banks, with actual dimensions of 11.375 inches wide by 23.375 inches high by 29 inches deep. It is suited for commercial HVAC systems requiring MERV 13 filtration in accordance with facility air quality standards. Typical applications include office buildings, schools, hospitals, and light industrial facilities where code or occupancy requirements call for enhanced particulate control. Rated airflow capacity is 1000 CFM at the standard face velocity.
Designed as a standard replacement bag filter for commercial air handling units and fan coil systems accepting a nominal 12 inches wide by 24 inches high by 29 inches deep filter section.
Installation should be performed by a licensed HVAC technician. Always shut down and lock out the air handling unit before removing the existing filter or installing a new one. Confirm that the filter bank frame dimensions match the actual filter size of 11.375 inches by 23.375 inches before installation to ensure an airtight fit and prevent bypass. Verify airflow direction arrows on the frame align with system airflow before securing the filter in place.
