Dampers are devices used in HVAC systems to regulate airflow. They can be found in ductwork, air handlers, and other parts of the system. Here are the main types and their functions:

Types of Dampers

1. Manual Dampers: Operated by hand, these dampers allow users to control airflow manually. They are often used in smaller or less automated systems.
2. Motorized Dampers: These are controlled electronically or by a thermostat, allowing for automated adjustments to airflow based on system demands.
3. Balancing Dampers: Used to balance airflow between different ducts, ensuring even distribution of air throughout a space.
4. Backdraft Dampers: Prevent air from flowing backward through the duct when the system is off, protecting against drafts and energy loss.
5. Fire Dampers: Designed to close automatically in the event of a fire, preventing smoke and flames from spreading through the duct system.

Benefits of Dampers

• Improved Airflow Control: Allow for precise regulation of air distribution, enhancing comfort and system efficiency.
• Energy Savings: By optimizing airflow, dampers can reduce energy consumption.​
• System Protection: Fire and backdraft dampers help protect building occupants and property from fire hazards and unwanted drafts.
• Comfort: Properly balanced airflow contributes to more consistent temperatures and humidity levels in different areas.
