DAMPER ACTUATOR - STANDARD, ON/OFF, RAISE/LOWER AND
The RA2 is a small and compact unit designed to
operate directly coupled to small air dampers in ventilation and air
conditioning systems like zone dampers, and used to control air flow in
ducts especially addressing 2 or 3-position and modulating 2-10Vdc
domestic and light commercial barrel damper applications.
For shaft dia 6 - 16mm round and 5 - 12mm square
With housing made in plastic and 0.9m connecting
Not less than 2Nm
30-35 sec for 24V and 230 V
80-110 sec for modulating 2-10V
up to appr. 0.5m2
1 x SDPT potential free
Adjustable up to 95 degree
The RA series damper actuators provide
optimal ventilation in a particular energy-efficient way, since only the
control function device consumes
power in end/stop mode.
In addition to energy savings, the damper
actuators also pay off due to their long service life.
Thanks to a very robust housing, they are
resistant to the rough conditions encountered during transportation,
storage and construction time.
Moreover, a functionally tested module concept
ensures maximum quality and reliability.
The RA4 range of Actuators require a
24Vac/dc or 230Vac supply and can either accept an on/off or floating (raise/lower)
control signal input.
Well-suited for applications with small dampers
up to 1,0m2 in ventilation- and air handling units.
A range of low-cost direct-coupled damper motors
The motors are compatible with the following input signals:
On/off and Floating Control with
24Vac or 230Vac electrical supply
A universal bracket allows simple direct coupling to dampers with round
and square shafts.
The motors feature reversible direction of motion, manual override,
adjustable angle of rotation, built-in auxiliary switches and screwed
They are available with 8Nm torque for damper areas of 2m2.
RA8, RA16, RA24
The RA-series damper actuators´ range covers every need in all HVAC
applications, from re-circulated air dampers, outside air dampers and
shutoff dampers to variable volume control and central air handling
