About Dampers

Dampers are critical components in HVAC systems, used to regulate and control the flow of air through ductwork. They can be manually operated or automatically controlled, depending on the application. Dampers come in a variety of shapes and sizes, such as round dampers for circular ducts or rectangular dampers for square/rectangular ducts. Depending on their design, they can be opened completely (fully open) or partially (partially closed). This allows them to direct airflow within an HVAC system, allowing users to adjust temperature settings in different areas of a building more precisely. Additionally, some dampers feature insulation materials like fiberglass which help reduce noise coming from an HVAC system while it is running.
