G90/PVC - Galvanized steel frame / PVC blades - Rear flanged
24"-54"
| The Model G90/PVC is an AGRICULTURAL rear flanged vertical mount automatic exhaust shutter for areas where corrosion may be a 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 cone or slant-wall exhaust fans. Do not use with vane axial or tube axial fans.
