ActronAir Zone Barrel Motor 24VAC is the genuine replacement motor for all ActronAir Integrated Zone Barrel assemblies, providing 24VAC drive open and drive close operation with 3Nm torque for reliable zone damper actuation. A failed zone motor leaves the damper blade in a fixed position, preventing zone control — fit the 100% Genuine ActronAir ZM-24V to restore factory zone performance without replacing the full barrel assembly. Low voltage inputs only — connecting 240VAC will damage equipment and void your ActronAir warranty.
