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
