Air Flow Products FB03INS000242624 Furnace Filter Box Insulation

Product Description

The AIR FLOW PRODUCTS FB03INS000242624 is a furnace filter box insulation panel designed to line the interior of a filter box housing in a forced-air heating and cooling system. It provides a thermal and acoustic barrier between the air handler or furnace cabinet and the surrounding mechanical space. At 24.5 inches by 26.44 inches by 24 inches, this insulation is sized for large-format filter box applications. HVAC installers and service technicians fit this panel during new installations or when replacing deteriorated lining inside an existing filter box assembly.

This insulation is suited for residential and light commercial forced-air systems where filter box housings require interior lining to reduce heat loss, limit condensation, and dampen airborne noise generated at the air handler. It is typically installed in vertical or horizontal filter box configurations upstream or downstream of the blower section, depending on system design. Installers working on larger tonnage residential systems or small commercial units will find the dimensions appropriate for wide-body filter box cabinets.

Key Features

• Large-format panel sized at 24.5 inches x 26.44 inches x 24 inches for wide-body filter box applications
• Designed to insulate and line the interior of furnace filter box housings
• Provides thermal separation to reduce heat transfer through the filter box cabinet
• Helps dampen airborne noise generated within the air handler or blower section
• Suitable for use in residential and light commercial forced-air HVAC systems

Compatibility

Designed as an OEM-style replacement insulation panel for large-format furnace filter box housings in forced-air heating and cooling systems.

Installation Notes

Installation is performed by a qualified HVAC technician. Power to the air handler or furnace must be shut off at the disconnect or breaker before accessing the filter box cabinet. The insulation panel should be fitted flush against the interior walls of the housing with no gaps that could allow air bypass. Verify that the panel does not obstruct filter seating, access doors, or airflow paths once installed.
