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.

Standard Construction:
Frame: 3" deep x 1-1/2" flange x 19 gauge G-90 Galvanized Steel with integrated weather stripping for strength and weather protection.
Blades: .065 thick Heavy Duty Extruded UV Stabilized PVC.
Tie Rod: Center mounted Stainless Steel for uniform opening and closing.
Bushings: 304 Stainless Steel screws, pins, and bushings.

We recommend mounting the shutter at least 1/3 the fan diameter away from the fan blade.
