OpenAir Rotary Electronic Control Damper Actuators-Spring Return
Low Torque Applications
GQD Series 20 lb.-in. torque
FEATURE | FUNCTION | BENEFIT |
|---|
Signal inversion capability | Select input signal operation of direct acting (2-10Vdc) or reverse acting (10-2Vdc) | Operate two actuators off one signal |
Fast running time | 30 seconds drive open and fail safe 15 seconds typical | Meets specifications that require run time of ≤ 30 seconds |
Plenum rating | 30 seconds drive open and fail safe 15 seconds typical | No conduit required for low voltage (24VAC/DC) plenum-rated product installed in a plenum space |
Small footprint | Compact design (4.7” × 2.7” × 2.5”) | Fits easily into tight spaces |
24 VAC/DC | Operate off of AC or DC power | Ability to operate off a DC backup power supply |
Low power consumption | 4VA typical | Lower energy consumption and power more actuators off one transformer |
Wide temperature operating range | Rated for operation from -25 °F to 130 °F | Withstands environments that other actuators cannot |
Medium Torque Applications
GMA Series 62 lb.-in. torque
Outside Air Dampers
Mixing Boxes
Small Rooftop Units
Return Air Dampers
Zone Isolation Dampers
Economizer Units
FEATURE | FUNCTION | BENEFIT |
|---|
Self-centering shaft coupling | Guarantees concentric fixation of actuator output coupling to damper shaft | Simplifies installation and eliminates damaging loads from high torque on damper shaft and actuator bearings |
Brushless motor technology | Quiet, low power operation; proven reliable technology | Lower energy costs and eliminates occupant complaints regarding noise |
Continuously engaged mechanical spring return | Returns damper to fail-safe position in response to power failure | Provides highly reliable fail-safe positioning compared to other types of actuators using an auxiliary spring winding motor |
All metal housing | Protects gear train and control electronics | Provides outstanding durability in the toughest environments |
Load independent | Maintains constant stroke time over all rated load and temperature conditions | Consistent control loop performance for all rated load and temperature conditions |
Stall protection | Actuator responds to blockage in damper | Motor is protected ensuring long actuator life and long equipment life |
Manual override | Allows unpowered positioning of shaft coupling | Simplifies installation, start-up, and troubleshooting |
Highly visible position indicator | Shows orientation of damper blades | Facilitates setup, checkout, and troubleshooting |
Wide temperature operating range | Rated for operation from -25 °F to 130 °F | Withstands environments that other actuators cannot |
