This 125 mm metal backdraft damper is designed for installation in round ducting and serves to prevent reverse air flow. The durable metal construction ensures a long service life and stable performance even with frequent use in residential and industrial installations.
Suitable for use with kitchen range hoods, bathroom and WC fans, or central ventilation. By installing a backdraft damper, you increase ventilation efficiency and reduce the ingress of cold air, odors, and contaminants back into the interior.
