DAMPER ACTUATOR - STANDARD, ON/OFF, RAISE/LOWER AND MODULATING

   

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 shaft.

With housing made in plastic and 0.9m connecting cable.

RA4
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.

RM8
A range of low-cost direct-coupled damper motors RM8.

The motors are compatible with the following input signals:

  • 0/2-10Vdc, 0/4-20mA

  • 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 connection termination.

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 units.

Regular functional tests ensure low noise damper actuators in continuous operation.

In addition, each actuator undergoes strict functional testing before delivery.

The RA8, 16 and 24 range of actuators require a 24Vac/dc or 230Vac supply and can either accept an on/off, floating (raise/lower) 0r 0(2)-10Vdc/0(4)-20mA control signal input.

Well-suited for applications with dampers up to 2.0, 4.0 resp. 6.0m2.

RA32
High comfort regarding room climate and operation.

Thanks to their fast and precise implementation of instructions from the building automation systems, the damper actuator help to provide ac comfortable room climate.

In addition, their brushless motor, gear trains that have already been run in and precisely mounted technology ensure especially quiet operation.

This ideal for areas where intensive work I carried out, as well as for night-time operation, e.g. in hotels and hospitals.

The RA32 range of Actuators require a 24Vac/dc or 230Vac supply and can either accept an on/off , floating (raise/lower) and
0(2)-10Vdc/0(4)-20mA control signal input.

Well-suited for applications with dampers up to 8m2.
