Mx41-7xxx Series
60 lb-in and 133 lb-in Direct Coupled Damper Actuators
Product Description
Designed for controlling air dampers in building systems that require
fail safe return, with two position, floating or proportional control.
Features
• Direct mount to round or square damper shaft
• 60 lb-in (7 N-m) and 133 lb-in (15 N-m) torque rating
• Overload protection throughout rotation
• Optional built-in auxiliary switches
• Provides true mechanical clockwise or counterclockwise spring return operation
for reliable positive close-off in airtight applications
• Direct acting or reverse acting control mode available on proportional models
• Rotation limiting available
• Rugged die-cast housing for NEMA 2/IP54 rating
• Manual override
• 5-year warranty
