GENERAL These direct-coupled damper actuators provide two-position and floating control for: • air dampers, • VAV units, • air handlers, • ventilation flaps, • louvers, and • reliable control for air damper applications with up to 4.6 m2 / 50 sq.ft. (20 Nm / 177 lb-in) or 7.8 m2 / 85 sq. ft. (34 Nm / 300 lb-in) (seal-less dampers; air friction dependent).

FEATURES • Self-centering shaft adapter • Access cover to facilitate connectivity • Service/off for safe & easy servicing • Rotation direction selectable by switch • Declutch for manual adjustment • Mechanical end limits • Field-installable auxiliary switches • Mountable in any orientation (no IP54 if upside down) • Mechanical position indicator • CE and UL certified (230V models with CE only)
