International Environmental 71159943 Actuator 318973-401 Electrolysis Mitigation: Utilizes AC current

Electrolysis Mitigation: Utilizes AC current on the probe circuit to minimize mineral buildup and electrode degradation

Heavy-Duty Construction: Zinc-plated steel components provide superior resistance to corrosion and mechanical wear in industrial HVAC environments

Direct OEM Replacement: Replaces discontinued model 025-29139-003 for simplified system maintenance

and an integral drain port

Precision Engineering: The shaded pole motor design provides consistent 1550 RPM performance required for specific blower wheel calibrations

International Environmental 71159943 Actuator 318973-401 Electrolysis Mitigation: Utilizes AC currentThe International Environmental 71159943 Actuator is a field proven 24V N C 2 position actuator designed for high cycle performance in HVAC fan coil units, air handlers, and VAV systems. This direct drive actuator operates with a normally closed (N C) configuration, ensuring the valve defaults to a closed state upon power loss to prevent uncontrolled flow. Engineered as a genuine IEC replacement part, this model is cross referenced with Erie
