What is the main purpose of a dampener within an HVAC system?

The main purpose of a dampener within an HVAC system is to control the volume of airflow. Dampeners are installed in ductwork to regulate the amount of air that flows through a specific section of the system. By adjusting the position of the dampener, you can increase or decrease the airflow to different areas, ensuring that each space receives the appropriate temperature and comfort level as needed.

This capability is crucial for achieving efficient system operation and maintaining indoor air quality, as it allows for precise control over the distribution of heated or cooled air throughout the building. It also helps to balance the system, compensating for uneven airflow that can occur due to variations in duct size, length, and layout. Proper use of dampeners aids in energy efficiency, prevents drafts, and enhances overall comfort in residential and light commercial environments.
