WD-210 : Motorized Backdraft Damper
WD-210 : Motorized Backdraft Damper
The WD-210 is a motorized backdraft damper designed to open when energized and spring-return closed when de-energized, delivering dependable, fail-safe airflow control. Suitable for horizontal or vertical mounting, it features a flange on the motor side for secure duct connection and simplified installation. Electric motorpacks ship separately to allow application flexibility. Ideal for use with roof or sidewall supply (intake) fans, the WD-210 helps prevent undesirable reverse airflow and protects system performance when fans are not operating.
