GENERAL
These direct-coupled damper actuators provide modulating
control for:
• rotary valves,
• air handling units,
• ventilation flaps,
• louvers, and
• reliable control for air damper applications with up to 50
sq.ft. (20 Nm / 175 lb-in) or 85 sq. ft. (34 Nm / 300 lb-in)
(seal-less damper blades; air friction-dependent).
FEATURES
• New self-centering shaft adapter
• Access cover to facilitate connectivity
• Declutch for manual adjustment
• Mechanical end limits (MN7220 only)
• Field-installable auxiliary switches
• Rotation direction selectable by switch
• Mountable in any orientation (no IP54 if upside down)
• Mechanical position indicator
