Product Details
The Model 502 is an economy rear flanged vertical mount automatic exhaust shutter designed to facilitate horizontal airflow in one direction while preventing reverse airflow and protecting against environmental elements when the airflow ceases. This automatic exhaust shutter features blades that open with airflow and close by gravity when the fan is turned off, making it ideal for use with direct-drive or belt-driven exhaust fans, but it should not be used with vane axial or tube axial fans. Constructed in the USA, the Model 502 ensures reliable operation and compliance with applicable standards.
