Product Introduction:
The air volume damper has the features of simple construction, low leakage, small torque, flexible operation, corrosion resistance. This series of air flow damper is indispensable central air-conditioning terminal fittings which used in industrial factory building civil building ventilation, air regulating and air purification engineering It is generally used in air conditioning, ventilation ducts, to adjusting the air flow of branch pipe, also can be used in the fresh air and return air mixed regulation. The air dampers have manual control and motorized control.
