Spring return electronic damper actuators     

Spring return

OpenAir™ electronic rotary spring return damper actuator series offers torques ranging from 20 lb-in to 160 lb-in with a variety of standard control signals and built in-options. Ideal for economizer dampers, roof top unit and air handling unit control.

The energy efficient spring return damper actuators offer 15-second spring return capability and 90-second drive open timing;  with GQD offering 30-second drive open timing. All actuators are plenum rated. The patented self-centering shaft adapter concentrically holds shaft with no slipping or call backs and saves installation time. The actuators (except GQD) also offer manual override to move the equipment in the absence of power.
