20-Inch Aluminum Gravity Intake Wall Shutter

This gravity-operated wall shutter is designed for commercial ventilation installations that bring supply air into a building. It gives facility and HVAC buyers a vertically mounted intake opening that opens by gravity when airflow is present and closes with spring assistance when airflow stops.

The shutter has a rear flange and mill-finish aluminum frame and blades. Each blade includes a galvanized reinforcement strip and a felt leading-edge seal. For vertical supply-intake mounting, the blades pivot from the bottom to open by gravity and are spring-assisted for closing. It is intended for use with belt-driven centrifugal wall ventilators. Overall dimensions are 23 in. wide x 23 in. deep x 3 in. high.

Key Features:

• Gravity-operated blades: Blades open with gravity for supply-air intake operation.
• Spring-assisted closing: Helps the shutter return toward a closed position when airflow stops.
• Reinforced aluminum blades: Galvanized strips add strength and support blade counterbalancing.
• Felt blade seals: Helps provide quieter closing and improved weather protection.
• Rear-flanged design: Supports wall-shutter installation for vertical intake applications.

Choose this 20-inch aluminum wall shutter for vertically mounted supply-intake ventilation systems using compatible belt-driven centrifugal wall ventilators.
