Frequently Asked Questions

What is the Dayton backdraft damper used for?

The Dayton fiberglass backdraft damper is used to prevent reverse airflow in exhaust systems, typically paired with a 20-inch fan. It is wall-mounted in a vertical position and handles horizontal airflow, making it suitable for industrial ventilation, commercial kitchens, and manufacturing facilities where one-way airflow is critical.

What are the specifications of the Dayton backdraft damper?

The Dayton is a single-panel flat-blade damper measuring 23 inches high, 23 inches wide, and 3 inches deep. It has a maximum air velocity of 2500 fpm, mounts vertically, and directs airflow horizontally. The fiberglass construction resists corrosion, and the blade type is flat for reliable backdraft prevention.
