Damper Actuators
Description
This range of damper actuators are suitable for many applications including motorised control of dampers in ventilation systems. They are available with either on/off, floating (raise/lower) or modulating control signal input and various torque ratings. A failsafe damper actuator is also available in a 20Nm (177 in/lb) torque rating.
All units and can have optional auxiliary switch(es) fitted and the direction of rotation can be reversed and the angle of mechanical travel can be limited.
