INDUSTRIAL DAMPER ACTUATORS - NEMA 3R/IP54 (waterproof
Rotational speeds from
1.5 to 8 sec
Torque: 2.8, 4.0, 5.6 Nm
Primary uses for these actuators:
fume hood control
air handler dampers
These microprocessor based actuators are designed for
critical for environments where the speed of the actuator is essential.
All actuators are bi-directional. Enerdrive actuators are also
bi-directional under fail safe conditions. The stroke may be limited to less than
The BM and BT damper actuator has been designed
for commercial and industrial ventilation applications. The protection
class is IP54 with proper glands and can be installed in any in-door
The actuator is being used in high rise office
blocks for the ventilation control or in many clean room pressure or
constant air volume applications where a fast and reliable air volume
control must be achieved.
It is also used in fume cupboard extract and make
up air laboratory control where long term reliability is required.
It has a rotating clamp which can grip 8..12mm
square damper shafts or 8..16mm round damper shafts.
It will fit perfectly onto the fume cupboard
The motors are best used with the CMR dampers as
the rotating shaft and gear mechanism on the damper must be able to
withstand very fast small open and closed commands under automatic
The actuator has a synchronous 24VAC motor which has the advantage that
it cannot be overloaded.
Two adjustable end switches are fitted to stop
the motor on closed and on open positions.
Two additional adjustable end switches with volt
free contacts are available for indication on closed and open position
for other control systems.
A manual push button clutch mechanism can be
operated by hand.
When pushing the manual button, it disengages the
gear drive to the application. The clamp can then be rotated manually to
The power should be isolated before using the
manual push button as otherwise the motor drives back to the control
position when the button is released.
This function should only be used in a controlled
When there is a power failure, the motor shall
remain in its last position.
An open/closed alternative also exists.
The motor has been factory tested and is
