HVAC Damper

Nov. 23, 2022

An HVAC Damper is a device that regulates the flow of heated or cooled air within a ventilation system. Dampers come in various styles, including manual, motorized, and automatic control dampers. Manual dampers are operated by a lever or handle, while motorized and automatic dampers are controlled by an electric motor and internal sensors.

An HVAC damper is used to control the air flow within a ventilation system and is typically installed in ducts, walls, or ceilings. It allows users to adjust airflow in one area while preventing excessive amounts of air from entering other areas. This helps improve energy efficiency by preventing the overuse of heated or cooled air in a particular area. HVAC dampers can be used to control air flow in both residential and commercial buildings, depending on the size of the damper and the type of ventilation system being used.

 

 

Additionally, HVAC dampers play an important role in improving indoor air quality. By controlling airflow, they help reduce allergens and pollutants, such as dust and pollen, from entering a space. This helps to improve air quality and keep the environment safe and healthy for everyone.

Overall, HVAC dampers are an essential part of any ventilation system as they help regulate airflow and improve energy efficiency. They also play an important role in improving indoor air quality by helping to reduce allergens and pollutants. If you need to install an HVAC damper in your home or business, it is important to choose the right type of damper for your system so that you can get the most out of it.
