Reliable metal backdraft damper 150 mm prevents unwanted airflow back into the system. Ideal for ventilation and exhaust ducts, ensuring stable pressure, lower noise, and higher energy efficiency.
This durable in-duct backdraft damper with a 150 mm diameter is designed to reliably prevent reverse flow in residential and commercial HVAC installations. The metal construction ensures long service life and consistent performance even with frequent operation.
It installs directly into round ducting and operates automatically – it opens when air flows and closes when it stops, preventing cold air, odors, and debris from entering the interior.
