Pro-source PRO40039-P Merv 14 Pleated Air Filter 12x24x12

Product Description

The PRO-SOURCE PRO40039-P is a MERV 14 V-Bank mini-pleat pleated air filter designed for commercial and industrial HVAC air-handling systems that require high-efficiency particulate capture in a compact, deep-bed configuration. Constructed with a microfiberglass media arranged in a V-bank pleat pattern, the filter delivers 1,250 CFM of rated airflow through a nominal 12 x 24 x 12 inch envelope. The plastic frame integrates directly with the media pack for structural rigidity without added metal hardware. Initial resistance starts at 0.20 inches w.g. at 375 FPM, rising to 0.37 inches w.g. at 625 FPM, keeping static-pressure drop predictable across a wide operating range. HVAC technicians and building engineers specify this unit where high-dust-loading environments demand a MERV 14 rating.

This filter fits applications including commercial office buildings, hospitals, laboratories, clean manufacturing environments, and any air-handling unit requiring high-efficiency filtration within a 12 x 24 x 12 inch filter bank. Its V-bank geometry maximizes media surface area within the nominal depth, extending service intervals compared to standard flat-panel pleated filters. The unit is rated for continuous operation up to 150 degrees F, making it suitable for systems with elevated supply-air temperatures. Mechanical contractors and building maintenance professionals use this filter in multi-filter housings and dedicated filter banks where MERV 14 performance is specified by design or code.

Key Features

• MERV 14 efficiency rating for high-particulate capture in demanding environments
• V-bank mini-pleat microfiberglass media maximizes surface area within the 12-inch nominal depth
• Rated airflow of 1,250 CFM with a maximum face velocity of 750 FPM
• Low initial resistance: 0.20 inches w.g. at 375 FPM, 0.28 at 500 FPM, 0.37 at 625 FPM
• Integrated plastic frame eliminates loose components and simplifies installation
• UL 900 listed for flammability compliance in commercial air systems
• Maximum operating temperature of 150 degrees F for elevated-temperature AHU applications

Compatibility

Designed as an OEM-style replacement or new-install filter for commercial and industrial air-handling units and filter banks accepting a nominal 12 x 24 x 12 inch deep-bed pleated filter with a MERV 14 specification.

Installation Notes

Installation of this filter should be performed by a qualified HVAC technician following the AHU manufacturer's service procedures. Power down and lock out the air-handling unit before opening the filter access panel. Confirm airflow direction arrows on the filter frame align with the system's designed airflow path before seating the filter. Verify that the housing gasket or frame seal is fully engaged to prevent bypass air from circumventing the media.
