Direct-Coupled Replacement Damper Actuators for Residential Rectangular Zone Dampers

The MEP-5223 and MEP-5233 are replacement damper actuators designed for residential dampers. The 24 VAC, tri-state, 10 inch-lbs., direct-coupled actuator provides smooth and quiet performance, with fast, 15-second closings and openings.

These actuators are intended for replacement on series B and C style residential dampers only—not the A series dampers. The MEP-5223 is intended for replacement on round dampers with a fully closed blade angle of 45 degrees. The MEP-5233 is intended for replacement on rectangular dampers with a fully closed blade angle of 90 degrees.

  • Fast, 15-second closings and openings.
  • Tri-state operation.
  • Models for round (MEP-5223, 45°) and square (MEP-5233, 90°) dampers.
  • 1/2" (12.7 mm) direct-coupled mounting for securing to damper blade shaft.
  • Position indicator and angular rotation stop for viewing and setting minimum and maximum damper positions.
  • Disengagement feature to manually position actuator and damper blade.
