Dampers

Air control dampers are devices that regulate or stop the airflow within a duct, chimney, vent, or similar piece of equipment.
They are a crucial component of HVAC systems that help to increase comfort and energy efficiency while prolonging the lifespan of the HVAC unit.
Here are some key points to understand about air control dampers:

Purpose:

Air control dampers are used to regulate the flow of air in HVAC systems, which can help to control the temperature and climate of individual rooms or zones.
They can also be used to cut off central air conditioning or heating to an unused room.

Types:

There are two primary types of air control dampers: automatic and manual
Manual dampers are turned by a handle on the outside of a duct, while automatic dampers are operated by electric or pneumatic motors, which are controlled by a thermostat or building automation system.

Operation:

Air control dampers work by utilizing blades, plates, or valves to regulate or stop the airflow within a duct or air-controlling piece within the unit.
The actuated blades of the dampers allow you to control the amount of airflow you desire and where you wish to direct the flow.

Adjustment:

Dampers can be adjusted by opening or closing the damper flap or valve, which is typically found in ductwork.
Adjusting dampers is a great way to control the airflow in your HVAC system.
