The SOUTHWARK METAL 16X20FILTERRACK is a steel filter rack designed to house standard 16 x 20 inch air filters in residential and light commercial HVAC ductwork systems. Filter racks provide a dedicated slot in the return-air duct or air handler cabinet to hold a flat-panel filter securely in place, preventing air bypass around the filter media. This unit is intended for installation by licensed HVAC technicians or experienced mechanical contractors working on forced-air systems.
The 16X20FILTERRACK is sized to accept the widely used 16 x 20 inch filter format, making it a practical solution for return-air grille installations, inline duct filter sections, or air handler filter slots in residential and small commercial forced-air heating and cooling systems. It provides a clean, secure mounting point to ensure consistent filter contact and proper airflow through the filter media.
Designed as an OEM-style filter rack for use with standard 16 x 20 inch flat-panel air filters in forced-air HVAC duct systems.
Installation should be performed by a qualified HVAC technician in accordance with local mechanical codes. Power down the air handler or furnace at the disconnect before accessing the duct system or filter cabinet. Ensure the rack is oriented correctly for the direction of airflow as indicated on the filter media. Confirm all duct connections are sealed after installation to prevent conditioned air or return air from bypassing the filter rack.
