Pro-source Extended Surface Multi-cell Rigid Filters

Overview

The PRO-SOURCE PRO14966 is a MERV 11 rigid cell pleated air filter built for commercial and residential HVAC systems requiring deep-depth, high-efficiency filtration. Constructed with a fiberglass pleated media and a galvanized steel frame, this filter handles airflows up to 500 CFM and operates at temperatures up to 180 degrees F. At MERV 11, it captures fine particulates including dust, pollen, mold spores, and fine dust mite debris. The rigid cell design maintains media integrity under sustained airflow, resisting collapse at higher static pressure differentials. HVAC technicians and facilities maintenance professionals install this filter in air handlers, rooftop units, and large fan coil cabinets where a 12-inch deep filter section is specified. The PRO14966 is suited for applications demanding a high-capacity deep-bed filter with low initial resistance. Nominal dimensions of 24 x 12 x 12 inches (actual 23.38 x 11.38 x 11.375 inches) fit standard 12-inch-deep filter housings in commercial air handling units and built-up systems. Initial resistance starts at 0.13 inches water gauge at 250 FPM, rising to 0.39 inches water gauge at the rated 500 FPM airflow, giving system designers predictable pressure drop data for fan selection. Final resistance at rated FPM is 1.5 inches water gauge, providing a clear end-of-life indicator for scheduled maintenance programs.
