. . . . . Belimo AFA24-SR Spring Return Fail-Safe, Proportional Damper Actuator, Direct Coupled - 24 VAC/DC (No Aux Switch)Features:Cut labor costs with simple direct couplingTrue mechanical spring return - the most reliable fail-safeReverse mount for clockwise or counterclockwise fail-safeCheck damper position easily with clear position indicatorOverload-proof throughout rotationTemporary restrictions in damper movement will not change actuator operation. Actuator returns to normal operation when restriction is removed (modulating actuators)Easy mechanical stop to adjust angle of rotation (add ZDB-AF2 US US accessory)By eliminating internal condensation Golden Point breather membrane optimizes performance in harsh airstream environmentsBuilt-in auxiliary switch is easy to use, offers feedback or signal for additional device (-S models)Manual override crank speeds installationNeed to change control direction? Do it easily with a simple switch (modulating actuators)Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators)Rugged metal housing withstands rough handling in the mechanical room3 ft. appliance cable and conduit connector eases installationDouble insulated - no need for separate safety ground. A Belimo exclusive (-S,120V, 230V models)Automatically compensates for damper seal wear, ensuring tight close-offThe AFA24-SR is used for proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer's specifications.The AFA 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 constant torque to the damper with, and without, power applied to the actuator.. Belimo. Belimo. AFA24-SR.
