The AIR FLOW PRODUCTS FB03INS000222424 is an air handler unit filter box insulation panel designed to line the interior of AHU filter boxes, reducing heat transfer and minimizing condensation on the unit casing. At 24.6875 inches x 22.6875 inches x 24 inches, this insulation piece is sized for direct installation inside commercial or residential air handler filter sections. HVAC technicians and sheet metal installers rely on properly fitted filter box insulation to maintain system efficiency and prevent moisture-related damage to the surrounding cabinet structure.
This insulation panel is suited for filter box applications on air handling units where thermal and vapor control inside the filter section is required. Typical installation scenarios include new AHU commissioning and retrofit insulation upgrades on existing filter cabinets that have degraded or missing liner material. The panel dimensions make it appropriate for medium to large AHU configurations commonly found in light commercial and residential replacement applications.
Designed as an OEM-style replacement insulation panel for air handler unit filter box assemblies where the installed dimensions match 24.6875 inches x 22.6875 inches x 24 inches.
Installation is typically performed by a licensed HVAC technician or qualified sheet metal installer. Shut down and lock out the air handling unit before removing or installing any interior liner panels. Verify panel dimensions against the filter box cavity before cutting or fitting. Follow local mechanical codes and manufacturer guidelines for approved insulation materials used inside air-side equipment.
