In larger structures, like office buildings, HVAC systems must pass air across great distances to heat and cool interior spaces. This difference dictates how each damper operates and its intended uses. Control dampers regulate airflow through duct work by opening and closing their blades. Most people focus mainly on the air conditioning part of an HVAC system, but they do more than condition air. Also known as a Volume Balancing Damper, air control dampers are used in situations to control airflow and are considered medium to heavy duty. Every damper is built with performance in mind and tested per AMCA standards in Ruskin's Laboratory. This simple action can serve many purposes, such as directing airflow to a specific part of the building or for mixing hot and cold air streams for air conditioning. Optional construction is of 18ga. A balancing damper's blade action is not designed to direct airflow, but to maintain a specific angle to regulate air pressure. galvanized steel including the balancing blades.
