Our ZBF-150AS includes an air proving switch. Once the dryer is turned on, the exhausting air triggers the switch which turns on the dryer booster fan.
Like our ZBF-150, the DB150AS has a low profile for tight installations where required; installs vertically or horizontally with integrated mounting flanges. It also has a self cleaning motor which helps to prolong the life of the motor.
