Pro-source PRO14966 Pleated Air Filter Merv 11 24x12x12

Product Description

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.

Key Features

• MERV 11 pleated fiberglass media for effective mid-range particulate capture
• Rigid cell construction maintains pleat geometry and prevents media collapse under sustained airflow
• Galvanized steel frame resists moisture and corrosion in humid air handler environments
• Rated to 500 CFM maximum airflow with fully published pressure drop curve across four FPM points
• UL 900 listed filter media for fire-safety compliance in commercial installations
• Maximum operating temperature of 180 degrees F suitable for systems with elevated discharge air conditions

Compatibility

Designed as an OEM-style replacement for HVAC air handling units and fan coil cabinets specifying a nominal 24 x 12 x 12 inch rigid cell deep-bed filter section.

Installation Notes

A licensed HVAC technician or qualified maintenance professional should install this filter. Always de-energize the air handling unit and confirm airflow has stopped before opening the filter access panel. Verify the filter housing accepts a 12-inch nominal depth cartridge and confirm actual clearance dimensions against the actual filter size of 23.38 x 11.38 x 11.375 inches before installation. Ensure the filter is seated flush against the housing gasket or track seal to prevent bypass air around the media frame.
