The Damper or Volume Control Damper is a metal insert for our range of square diffusers.
The damper can be retro-fitted and allows the balancing of airflow between diffusers connected to the same main duct.
The damper is simply two plates of galvanised steel. The smaller plate rotates over the larger, fixed plate, closing or opening the air gap. Once balance has been achieved, the damper can be locked into place by bending the nibs.
