OpenAir™ GCA Series Spring Return 160 lb-in Electronic Damper Actuator
ASK71.1U: Allows foot mounting of OpenAir
actuators. Should be used for in-the-air stream
applications, and generally, anywhere a foot-
mounted actuator can be mounted. Kit contains:
•
Crank arm for changing angular rotation into
a linear stroke.
•
Support bearing ring to minimize side
loading on the actuator's output bearing.
•
Mounting bracket.
•
Required mounting fasteners.
ASK71.2U: Allows mounting OpenAir actuators
directly to damper frame. Should be used with
louvers and vents and in applications where floor
mount kit is not possible. Kit contains:
•
Crank arm for changing angular rotation into
a linear stroke.
•
Support bearing ring to minimize side
loading on the actuator's output bearing.
•
Mounting bracket.
•
Required mounting fasteners.
ASK71.3: Allows direct-coupled actuator to
provide an auxiliary linear drive. Crank arm kit
can be used to simultaneously drive a set of
opposing or adjacent dampers with single
actuator. Kit includes:
•
Crank arm to attach to the splined hub of the
shaft adapter.
•
Other required mounting fasteners.
ASK71.4: Allows economical mounting of
OpenAir actuator to a variety of surfaces. Kit
should be used in applications where the
actuator can be rigid-surface mounted and linear
stroke output is required. Kit includes:
•
Crank arm to attach to the splined hub of the
shaft adapter.
•
Mounting bracket.
•
Other required mounting fasteners.
ASK73.1: Bracket provides an extended anti-
rotation pin allowing two OpenAir actuators to
directly drive a single damper shaft. Tandem
mounting bracket for two GCA 2-position and
floating control actuators mounted on the same
side of the damper shaft.
