Volume Control Damper and Ceiling Register
Volume Control Damper and Ceiling Register
(OP)
When making HVAC duct layout, do I need to specify volume control damper in branch duct if ceiling supply diffuser has the opposed blade damper?
Otherwise, having VCD in branch duct, shall I specify ceiling supply diffuser without OBD?
Please advise.
thank you.

Washrooms and un-occupied type spaces (storage rooms) would be fine with a terminal damper.

I agree with the opposed blade dampers at the diffuser for fine tuning only.
