Constant air volume dampers for circular duct, which facilitates balancing of ventilation systems. Those dampers maintain the constant air volume within a zone of pressure between 50 and 250 Pa. SKP is a self-adjustable damper. The SKP damper is operated by an opposed opening force from a spring on the blade. Housing and regulator blade are constructed from plastic and tightness joint from rubber.
