Air Flow Products FB03INS000212224 Ahu Filter Box Insulation

Product Description

The AIR FLOW PRODUCTS FB03INS000212224 is an air handler unit filter box insulation panel designed to line or wrap AHU filter box assemblies in forced-air HVAC systems. This insulation component reduces heat transfer and limits condensation on filter box surfaces, helping maintain system efficiency and preventing moisture-related issues inside the air handler cabinet. At 21.125 inches by 22.0625 inches by 24 inches, it is sized for a specific filter box opening and is typically installed by licensed HVAC technicians during new construction, system replacement, or scheduled maintenance.

This filter box insulation is suited for residential and light commercial air handler installations where the filter box section requires thermal and acoustic insulation. It is commonly used in split-system and package unit applications where the AHU is installed in unconditioned spaces such as attics, mechanical rooms, or utility closets, where thermal performance of the filter compartment is a priority.
