EASR - Aluminum frame and blades - Front flanged 10"-60" Maximum velocity 2500 FPM

The Model EASR is a COUNTER BALANCED front flanged vertical mount automatic exhaust shutter. 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 minimize the wear load on the fan motor and close by gravity when the fan shuts down. Counter balanced blades allow the shutter to be mounted vertically to 45 degrees and has flanged ends for added weather protection. Ideal for direct-drive or belt-driven exhaust fans. Do not use with vane axial or tube axial fans.

Standard Construction:
Frame: 3" deep x 1-1/2" flange x .080 6063T5/6 Extruded Aluminum with integrated weather stripping for strength and weather protection.
Blades: 26 gauge 3105 Aluminum with a Galvanized reinforcement strip across top of blade for strength and counter balancing.
Seals: Felt on leading edge of blades for tight closure and quiet operation.
Tie Rod: Center mounted Galvanized Steel for uniform opening and closing.
