Product Details
The Model 556 is a counter balanced rear flanged vertical mount automatic exhaust shutter designed to facilitate horizontal airflow in one direction while preventing reverse airflow and safeguarding against environmental elements when airflow ceases. This automatic shutter features blades that open with airflow, minimizing wear on the fan motor, and close by gravity when the fan shuts down. Its counter balanced blades enable vertical to 45-degree mounting, with flanged ends providing additional weather protection. This product is ideal for use with direct-drive or belt-driven exhaust fans, but it is not suitable for vane axial or tube axial fans. The dimensions and specifications ensure reliable performance, and it is proudly made in the USA. The product includes a warranty that adheres to standard terms for quality assurance.
