An Aluminum Collar Damper is a type of damper used in HVAC (Heating, Ventilation, and Air Conditioning) systems. The collar damper specifically refers to the shape of the damper, which resembles a collar that fits into the ductwork. These dampers are typically made of aluminum, which is lightweight, durable, and resistant to corrosion. Aluminum is a common material choice for HVAC components due to its favorable properties. They are often installed in ductwork branches or outlets to control airflow to specific zones or rooms. Aluminum Collar Damper plays a crucial role in HVAC systems by providing precise control over airflow, which helps to optimize system performance, energy efficiency, and indoor comfort levels.
