Belimo EFB24-MFT-S Damper Actuator in-lb Spring Return NEMA - 270 24V 4

The Belimo EFB24-MFT-S is a high-performance electric damper actuator designed for precise control of HVAC dampers in commercial building automation systems. This robust actuator delivers 270 inch-pounds of torque with spring return functionality for fail-safe operation.

Key Features:

• 270 in-lb (30 Nm) torque output for demanding damper applications
• 24V AC/DC power supply for flexible installation
• Spring return (SR) operation ensures damper returns to fail-safe position on power loss
• MFT (Multipurpose Floating/2-10V) control signal for versatile integration
• 2-10 VDC auxiliary feedback signal for position monitoring
• NEMA 4/IP54 rated enclosure for indoor and protected outdoor environments
• Switchable direction of operation for installation flexibility
• 90-second running time for efficient damper control
• Compact design with standard mounting pattern

This actuator is ideal for variable air volume (VAV) systems, air handling units, and general HVAC damper control applications requiring reliable performance and precise positioning. The spring return feature makes it particularly suitable for life safety applications where dampers must return to a safe position during power outages or emergencies.
