Damper Actuator | 35 in-lb | Spg Rtn | 24V | On/Off



For On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is On/Off from an auxiliary contact or a manual switch. The actuator is mounted directly to a damper shaft from 3/8†up to 1/2†in diameter by means of its universal clamp, 1/2†shaft centered at delivery. For shafts up to 3/4†use K6-1 accessory. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.


The LF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The LF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode. The actuator is double insulated so an electrical ground connection is not necessary

Highly recommended!

Ive heard about the LF24 US Damper Actuator since I needed to buy it for my new gas system and my friends told me about it. And I must say that it works quite more than I have ever imagined. It has mechanisms that can detect whatever damage my gas system can have or not. Its power consumption is lower than I expected, especially when . Why is this switch important? This is so that the device can be safely interacted within the maximum rotation of 95 degrees. If thats not enough, the LF24 US has a warranty for around 5 years, and it comes with free shipping by Belimo. Totally worth it.

Easy to install

This LF24 US Damper Actuator made by Belimo is quite easy to install. It began when I first worked on upgrading my oh so noisy ventilation system. I searched through the Net for this since I heard that this one was good, and indeed it is. It can be rotated up to 95 degrees, with an anti-rotation strap to prevent the device from moving sideways. Its power consumption is greatly reduced when placed in holding mode, and is also electronically and doubly insulated. That meant an electrical ground connection was no longer needed inside my house. Reliable and worthwhile, this product is worth all my upgrades. Recommended.
