Volume Control Dampers


Volume control dampers are specially designed for low leakages of air. Dampers are available in GI opposed blade type, aluminum extruded blade type, face and bypass. The blades are connected through suitable linkage to a controlling actuating device, such as electrical actuator or fusible link. Blades are provided with brass or nylon bush with gear operated or MS linkage facility to enable smooth and Noiseless rotation.

FIRE dampers are made of heavy guage galvanized steel having multi blade construction. The blades of the fire damper are held in the open position by a high tensile spring and a fusible link. The fusible link is 'UL stamped' and operates at 74 degree C, causing the damper to close in case of fire. Thus the spread of fire through the ducts is prevented.
