Product Description
Aldes High-Performance Wall Hoods are designed for use in
exhaust or supply ventilation systems and fresh air kits. They
are engineered to accommodate high airflow pressure and
velocities found in premium fan and dryer vent systems. Wall
hoods are available as screened or dampered versions. Each
wall hood is designed to maximize airflow and minimize noise.
Construction
Wall Hoods are available in heavy-gauge G90 galvanized
steel.
Screened Wall Hoods
1/4” galvanized steel mesh. Suitable for use in exhaust or
supply ventilation systems and fresh-air kits.
Dampered Wall Hoods
For use 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 backdraft dampers are not
present at other locations within the duct system.
