Belimo EFX24 Damper Actuator 270 in-lb Spring Return

Product Description

The BELIMO EFX24 is a damper actuator with 270 in-lb torque and spring return. It operates on 24 VAC and is designed for on/off control. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. It provides constant torque to the damper with, and without, power applied.

• Provides true spring return operation for reliable failsafe application
• Spring return system provides constant torque to the damper
• May be stalled anywhere in its normal rotation without the need of mechanical end switches

Product Highlights

The BELIMO EFX24 damper actuator ensures failsafe application and positive close off on air tight dampers.
