Greenheck Backdraft Damper

A Greenheck backdraft damper is a type of ventilation system component designed to prevent the reverse flow of air. It is used in commercial and industrial ventilation systems to ensure that air is flowing in the correct direction. The damper is typically installed in the ductwork of the ventilation system and is designed to open when air is flowing in the desired direction, and close when air is flowing in the opposite direction. This helps to maintain the air pressure balance in the system, as well as prevent contaminants from entering the system. The Greenheck backdraft damper is an important part of any ventilation system, as it helps to keep the air clean and ensure that the system is operating efficiently.
