OpenAir GCA Series Spring Return 142 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
(4 each)
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.
ASK73.2U: Bracket provides an extended anti-rotation
pin allowing two OpenAir modulating actuator to directly
drive a single damper shaft. (For GCA16x Series only.)
