5 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.
