Honeywell N20 Series Non-Spring Return Direct Coupled Actuator, 175 lb-in

Non-Spring Return Direct Coupled Actuator, 175 lb-in
N20 Series

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 4.6 m2/50 sq ft (seal-less dampers; air friction-dependent).

• 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.
