Honeywell N23 Series Non-Spring Return Direct Coupled Actuator
These direct coupled damper actuators provide adjustable modulating control for air dampers, VAV units, air handling units, ventilation flaps, louvers, and reliable control for air damper applications with up to 7.9 m2/85 sq ft (seal-less dampers, air friction-dependent).
Control for air damper applications with to 85 sq.ft assuming 3.5 in-lb per sq ft of damper area, velocity independent Palented self-centering shaft adapter. Access cover to facilitatte 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.
