Description
The Schneider Electric (Barber Colman) MK-3121 Pneumatic Damper-Actuator is an efficient part used to control the dampers located in the HVAC systems. Having an operating air pressure of 8-13 PSI and an adjustable stroke of 2-4 inches, it regulates the airflow in the system to optimum levels. This actuator is suitable for HVAC systems such as air handling units, exhaust systems and variable air volume boxes. It has a long service life due to its sturdiness and the ability to change the stroke of the damper.
