The right damper actuator for any HVAC application
OpenAir™ electronic rotary non-spring return damper actuators use a patented self-centering shaft adapter, which concentrically holds the damper shaft with no slipping or call backs or the single point centered connection on the lower torque actuators. Perfect for VAV equipment use with the plenum rating which may eliminate the need for conduit if local code allows. Many of the actuators offer selectable modulating signals of either 0-10VDC or 2-10VDC. Manual override capability is available on all types.
