The single-blade damper is used to control and isolate air flow in rectangular ductwork.
The DSQ damper can have a hand-operated damper mechanism, an externally-mounted
actuator, or an actuator mounting. In the case of manual control, the rotation is carried
out using the handle. It is possible to lock the position of blade by two locking screws.
The standard version of DSQ is manual mechanism.
