Delivering \u003cstrong\u003e35 in-lb torque\u003c\/strong\u003e, this unit is designed for dampers up to approximately 8.5 square feet, ensuring positive shut-off and fail-safe operation during power loss. As a direct replacement for the \u003cstrong\u003eMA-7103\u003c\/strong\u003e, the LF24 features a universal power supply and a simplified mounting bracket that reduces installation time in the field. The mechanical spring return provides consistent torque output, making it ideal for \u003cstrong\u003econtrol damper actuators\u003c\/strong\u003e in demanding air handling applications. Its brushless DC motor technology eliminates the need for limit switches, protecting the gear train from stall conditions and extending the service life of the \u003cstrong\u003edamper motor\u003c\/strong\u003e. Designed for \u003cstrong\u003eHVAC zone control\u003c\/strong\u003e, the LF24 maintains a compact footprint while offering high reliability for both new construction and retrofit projects where performance and \u003cstrong\u003edamper actuator compatibility\u003c\/strong\u003e are non-negotiable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits for Contractors\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFail-Safe Reliability:\u003c\/strong\u003e Mechanical spring return ensures the damper returns to the safe position during power interruptions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Seamlessly replaces the \u003cstrong\u003eMA-7103\u003c\/strong\u003e and similar legacy 35 in-lb actuators.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaintenance-Free Design:\u003c\/strong\u003e Brushless DC motor prevents burnouts and eliminates the need for internal switch adjustments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Mounting:\u003c\/strong\u003e Includes a universal clamp for easy attachment to various shaft sizes and shapes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnergy Efficient:\u003c\/strong\u003e Low power consumption during both operation and holding modes optimizes system efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Belimo LF24 be used in outdoor applications?\u003c\/strong\u003e\u003cbr\u003e\nThis actuator features a standard NEMA 2 enclosure; for outdoor use, it requires a protective weather shield to prevent moisture ingress.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the typical stroke time for this actuator?\u003c\/strong\u003e\u003cbr\u003e\nThe LF24 typically operates the motor in 40 to 95 seconds, with a spring return timing of less than 25 seconds at room temperature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this unit come with auxiliary switches?\u003c\/strong\u003e\u003cbr\u003e\nThe standard LF24 model is an on\/off actuator without internal switches; if feedback is required, verify the specific sub-model suffix (such as -S) before installation.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
