10 Inch Wall Hood with Flap Damper

10 Inch Wall Hood with Flap Damper

Wall Hoods are designed for exhaust air systems, fresh makeup air intake fans, or HRV and ERV systems. They are engineered to accommodate high airflow pressure and velocities found in premium fan and dryer vent systems. The wall hoods are designed to maximize airflow and minimize noise.  They are available in 314 2B finish stainless steel or solid copper type Ca 110.

Dampered wall hoods are used in exhaust ventilation and dryer venting systems. A magnetic-catch damper ensures a tight closure when the fan is not running and eliminates damper flutter in windy conditions. These hoods should be used when back draft dampers are not present at other locations within the duct system.
