When it comes to mastering the world of commercial HVAC, understanding the essential role of dampers is important. In a nutshell, an HVAC Damper is a moveable plate that modifies the air flow in an HVAC system, regulating the amount of conditioned air that reaches the intended zone. It functions as a valve or gateway in supply, exhaust and fresh air ducts, allowing airflow in either direction. By opening and closing, HVAC Dampers play an essential role in creating, controlling and optimizing temperature in a building or space.
