Pneumatic Damper Actuators

Pneumatic Damper Actuators

More torque, less energy consumption

Siemens damper actuators ship ready to install, with built-in time and cost-saving features such as a patented self-centering shaft adapter, standardized wiring, and brushless motor technology. With torques ranging from 20 to 310 lb-in., this powerful and flexible line-up delivers out-of-the-box performance and long-lasting reliability for all types of HVAC applications.

The Powers® Controls No. 3 Pneumatic Damper Actuator is a compact, totally enclosed, rolling diaphragm-type actuator designed for modulating or two-position actuation of dampers or air valves. This actuator has a stroke length of 2-3/8 inches (60mm) and is available in nominal spring ranges of 3 to 7 psi (21 to 50 kPa), 5 to 10 psi (35 to 69 kPa) and 8 to 13 psi (55 to 90 kPa).

The Powers™ Controls No. 4 Pneumatic Damper Actuator is a totally enclosed pneumatic piston type actuator designed to operate dampers for ventilating systems, mixing box control, and other applications requiring a large effective diaphragm area and long stroke. This actuator has a stroke length of 4 inches (102mm) and is available in nominal spring ranges of 3 to 7 psi (21 to 48 kPa), 3 to 13 psi (21 to 90 kPa), 5 to 10 psi (35 to 69 kPa) and 8 to 13 psi (55 to 90 kPa).

Powers® Controls No. 6 Pneumatic Damper Actuator is a heavy-duty, rolling diaphragm, spring return actuator designed to drive large dampers, centrifugal refrigeration inlet vanes, and other applications requiring a large, effective diaphragm area and long 4 inch (102mm) stroke length.
