“How does the damper prevent air from flowing backward through the ducts?”

1-1 of 1 Answer

• The backdraft damper design of the Zephyr 10-inch round in-line damper prevents air from reverse flowing through the ducts. It achieves this by utilizing a spring-loaded flapper valve that opens when air flows in the intended direction and closes when airflow reverses, effectively blocking backward airflow.
