It is not compatible with multi-stage heat pumps or 120/240V line voltage systems

The FSLF is designed for smaller dampers requiring up to 30 in-lb

Optimized Conductivity: High-purity copper lead construction minimizes resistance for stable pilot flame sensing

Engineered for 120V 60Hz electrical systems with a power rating of 13 watts for reliable actuation

Siemens Building Technology GMA121.1U Actuator 323613-751 It is not compatible withThe Siemens GMA121. 1U is a heavy duty spring return damper actuator engineered for high demand HVACR applications requiring reliable fail safe operation. Operating on 24VAC DC, this direct coupled actuator delivers a robust 62 lb in torque (7 Nm), making it an ideal choice for managing return air, mixed air, and exhaust dampers in both constant and variable air volume systems. Built with a rugged, die cast aluminum NEMA 1 housing, this unit ensures
