Figure 1. Floor Mount Kit.
ASK71.1U: Allows foot mounting of the
OpenAir actuators. Kit should be used for
in-the-air stream applications or 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 of OpenAir
actuators directly to a damper frame. Kit
should be used with louvers and vents and
in applications where use of the floor
mount kit 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
• Required mounting fasteners

ASK71.3: Allows a direct-coupled actuator
to provide an auxiliary linear drive. Kit 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
• Required mounting fasteners

Bracket.
ASK71.4: Allows economical mounting of
an OpenAir actuator to a variety of
surfaces. Kit should be used in
applications where the actuator can be
rigidly 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
• Required mounting fasteners
