OpenAir direct coupled 24 Vac non-spring return rotary electric actuators are
designed for floating control of dampers.

• Compact, lightweight design

• Manual override

• Standard and plenum models available

• Feedback potentiometer models available

• cUL and UL listed, CE certified

• Independently adjustable dual auxiliary switches available

These actuators are used in constant or variable air volume installations for control
of HVAC dampers requiring up to 44 lb-in (5 Nm) or 88 lb-in (10 Nm) of torque.

ASK71.6 Allows economical mounting of an OpenAir

actuator to a variety of surfaces. Should be used in
applications where the actuator can be rigid-surface
mounted and a linear stroke output is needed.

ASK76.1U Provides the connection between the
actuator and conduit.

NOTE: GDE131.1T and GDE131.1N are not

compatible with the ASK76.1U.
