Designed for installation where a single central return air duct is used. It is easily surface-mounted in the location normally occupied by the return air grille of the central heating/cooling system. It may be installed in the wall or ceiling, making it equally adaptable for use with closet or attic installations. The only visible part of the installed unit is the attractive aluminum grille.

Technical Note

For commercial application, maximum recommended airflow per unit is 1,000 CFM.
