‘”aira” Offers Pneumatic Actuator Operated The butterfly or wafer damper can be a stack damper where sealing or tight shut – off is not all-important. This type is used as an isolating damper for flue – gas scrubbers. The butterfly damper is lightweight , simple , quickly actuated and often comparatively low in cost. In process work , oval shapes adapt to t hat shape of duct . Occasionally , a double – disc butterfly appears resembling a circular two-bladed louver damper. The drive for a butterfly damper is also simple , needing only 90° of motion . The torque requirement can vary widely over damper life , if corrosion and thermal effects are severe.
