Belimo ZS-300 Housing

The Belimo ZS-300 is an industrial-grade NEMA 4X weather shield designed to provide superior protection for direct-coupled actuators in corrosive or high-moisture environments. Constructed from 304 stainless steel, this enclosure protects Belimo GM, AM, NM, and LM series actuators from hazardous UV exposure, rain, snow, and chemical washdowns. The ZS-300 304 stainless steel enclosure features a heavy-duty gasket seal and secure mounting hardware to maintain the mechanical integrity of the HVAC actuator assembly. By isolating the drive motor and electronics from the ambient environment, it prevents premature failure due to oxidation or moisture ingress. This protective actuator housing is essential for rooftop damper actuator installations, mechanical rooms with high humidity, or coastal applications where salt air is a concern. The precision-engineered design ensures full range of motion for the universal shaft clamp while maintaining a watertight seal.

• 304 stainless steel construction provides maximum resistance to corrosion and chemical exposure.
• NEMA 4X rated protection ensures internal components remain dry during high-pressure washdowns and extreme weather.
• Compatible with a wide range of Belimo damper actuators, streamlining inventory for service contractors.
• Includes complete weather shield mounting hardware for efficient field installation on various damper shaft configurations.
• Extends the operational lifespan of the actuator motor by mitigating environmental stress.

Is the ZS-300 compatible with non-Belimo actuators?

While specifically engineered for the Belimo AM, GM, NM, and LM series, it may accommodate other actuators with similar footprints; however, the mounting holes and shaft clearances are optimized for Belimo direct-coupled actuator geometry.

Can this housing be used for outdoor rooftop applications?

Yes, the NEMA 4X enclosure is specifically designed for rooftop HVAC installations where protection against UV degradation and wind-driven rain is required.

Does the ZS-300 require additional gaskets for installation?

The unit comes with the necessary hardware to provide a secure seal, though contractors should ensure the conduit fittings used are also NEMA 4X rated to maintain the integrity of the weatherproof actuator housing.
