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 airflow ceases. The shutter features blades that open with airflow and close by gravity when the fan is turned off. It is ideal for use with direct-drive or belt-driven exhaust fans, but should not be used with vane axial or tube axial fans. The product is proudly made in the USA and is characterized by its durable construction and reliable operation.
