General
This non-spring return direct-coupled damper actuator provides modulating and floating/2-position control for:
- air dampers
- VAV units
- air handlers
- ventilation flaps
- louvers, and
- reliable control for air damper applications with up to 10 sq ft/ 44 lb-in. (5 Nm) and 20 sq ft / 88 lb-in. (10 Nm) (seal- less damper blades; air friction-dependent).
Features
- Declutch for manual adjustment
- Adjustable mechanical end limits
- Removable access cover for direct wiring
- Mountable in any orientation
- Function selection switch for selecting modulating or floating/2-position control
