Description
This non-spring return direct-coupled damper actuator offers modulating and floating/2-position control for air dampers, air handlers, ventilation flaps, and louvers. It provides reliable control for air damper applications up to 10 sq. ft./44 lb.-in. (5 Nm) and 20 sq. ft./88 lb.-in. (10 Nm) with seal-less damper blades, depending on air friction.
Features
Control for air damper applications with up to 50 sq ft assuming 3.5 in-lb per sq ft of damper area, velocity independent.
Patented self-centering shaft adapter.
Access cover to facilitate connectivity.
Declutch for manual adjustment.
Mechanical end limits.
Field-installable auxiliary switches.
Rotation direction selectable by switch.
Mountable in any orientation (no IP54 if upside down). Mechanical position indicator.
CE approved. UL approved.
