30-Inch Counterbalanced Automatic Exhaust Shutter

This automatic exhaust shutter is for facilities using compatible exhaust fans to direct air outward while helping block reverse airflow when the fan is off. Its airflow-operated blades open during exhaust operation and close after shutdown to help shield the opening from environmental elements.

The rear-flanged shutter has counterbalanced blades and flanged ends for added weather protection. It supports vertical mounting from vertical to 45 degrees. The blades open with airflow and close by gravity when the fan shuts down. Overall dimensions are 33.5 inches wide by 34 inches deep by 3.5 inches high. It is intended for direct-drive or belt-driven exhaust fans and should not be used with vane axial or tube axial fans.

Key Features:

• Automatic airflow operation: Blades open as airflow begins and close when the fan stops, eliminating manual adjustment.
• Reverse-airflow protection: Helps prevent air from flowing back through the opening after exhaust operation ends.
• Counterbalanced blades: Allows installation from vertical to a 45-degree mounting position.
• Rear flange and flanged ends: Provides added protection from environmental elements around the opening.
• Exhaust-fan compatibility: Pairs with direct-drive or belt-driven exhaust fans.

Choose this 30-inch automatic shutter for compatible direct-drive or belt-driven exhaust fan installations that need one-way horizontal airflow and gravity closing when the fan is off.
