ASK71.11: For in-the-air-stream
applications: Anywhere a foot-mounted
actuator can be mounted. Can also be
directly mounted to a damper frame with
louvers and vents and in applications where
use of the floor mount is not possible.
Kit contains:

• Crank arm to change the angular

rotation into a linear stroke.

• Support bearing ring to minimize side
loading on the actuator’s output
bearing.

• Mounting bracket.

ASK71.13: Allows a direct-coupled actuator
to provide an auxiliary linear drive. Can be
used to simultaneously drive a set of
opposing or adjacent dampers with a single
actuator.
Kit contains:

• Crank arm to attach to the splined
hub of the shaft adapter.

• Mounting fasteners.

ASK71.14: 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 required.
Kit contains:

• Crank arm to attach to the splined
hub of the shaft adapter.

• Mounting bracket.

ASK75.3U: GEB actuators are UL listed to
meet NEMA 3R requirements (a degree of
protection against rain, sleet, snow, and
damage from external ice formation) when
installed with ASK75.3U Weath er Shie ld and
outdoor-rated conduit fittings in the vertical
position.
