The VCMR is a mechanical constant volume damper. The damper is designed to maintain the design volume independent of inlet pressure. The design volume is easily set by adjustment of the external sliding scale. The operating range of the damper is 50 – 1000 Pa (±10%).
The housing and damper are manufacturered from galvanized sheet steel and the damper shaft is manufacturered from stainless steel. The bearings are maintenance free.
The VCMR constant volume damper is not affected by the mounting position and can be mounted horizontally, vertically or on an angle. Each unit can be fully adjusted on site within its operating limits.
