Motorized Air Damper adjusts a ventilation duct opening from an accessible control switch. Its actuator moves the blade assembly, allowing staff to change a concealed or elevated branch without reaching the damper itself.
Round spigot, flanged round, rectangular and round multi-blade constructions connect to different duct layouts. Material and actuator choices allow the operating arrangement to follow the installation.
