Main types of dampers:
Manual dampers: Operated manually via levers or handwheels, used in systems where adjustments are infrequent.
Motorized dampers: Automatically controlled by electric or pneumatic motors, ideal for systems that require dynamic and precise adjustments.
Isolating dampers: Used to completely close the airflow in a section of the system, for example, during maintenance operations.
Regulating dampers: Allow airflow modulation to balance the system or adapt to different operating conditions.
Materials and applications
Dampers are generally made of carbon steel, stainless steel, or aluminum to withstand conditions such as high temperatures, abrasive dust, or corrosive atmospheres. They are commonly used in centralized extraction systems, painting plants, bag filters, and industrial ventilation systems.
