Bypass Type
The Volume Control Damper is used to control air flow in air duct. The Volume control dampers help to adjust the air flow volume to the other parts of this duct system. These dampers can be fixed within the duct itself and can be automatic or manual.
Constant Air Volume
Motorized dampers are constructed of precision-formed parts so that a high standard of quality for the finished product can be achieved. They are designed for trouble-free operation without need for maintenance. The precision-formed blades ensure long-term consistent performance.
Pressure Independent Type
The gastight rectangular shut-off damper, Type GD-R, will be used in ventilation systems for sensitive areas, like the chemical, the pharmaceutical, the nuclear industry or bio-safety laboratories, where high leak tightness requirements apply.
