FGS - Fiberglass frame and blades - Rear flanged 10"-60"

The Model FGS is a FIBERGLASS rear flanged vertical mount automatic exhaust shutter for areas where corrosion is a known problem. It is designed to allow horizontal airflow in one direction and to prevent reverse airflow while providing protection from environmental elements when the airflow stops. The blades open with airflow and close by gravity when the fan shuts down. Ideal for direct-drive or belt-driven exhaust fans. Do not use with vane axial or tube axial fans.
