s OpenAir™ Air damper actuators GDB..1E Electronic motor driven actuators for open-close, three-position and modulating control ● ● ● ● ● Nominal torque 5 Nm Operating voltage AC 24 V ~ / DC 24…48 V ⎓ or AC 100…240 V ~ Mechanically adjustable span between 0...90° Pre-wired with 0.
Use The rotary actuators are used in ventilation and air conditioning plants to regulate and shut off air dampers: ● For damper areas up to 0.8 m2 (guideline, always observe damper manufacturer’s data). ● Suitable for use with modulating controllers (DC 0/2...10 V), open-close or three-position controllers for air dampers or air throttles. ● We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3point control to ensure continuous and accurate operation.
Actuator motor / Gears ● Brushless, robust DC motors ensure reliable operation regardless of load. The damper actuators do not require an end position switch, are overload proof, and remain in place upon reaching the end stop. ● The gears are maintenance free and low noise.
