Greenheck 318871 Motor

The Greenheck 318871 Motor is a high-performance OEM replacement motor designed for demanding commercial and industrial air-handling applications. This 1/6 HP blower motor operates at 115V and maintains a consistent 1075 RPM, ensuring reliable static pressure performance in Greenheck and Accurex ventilation systems. Engineered with a durable steel body and a dual shaft configuration (0.5-inch diameter), this PSC motor is thermally protected to prevent overheating during continuous operation.

For contractors performing localized repairs or full system maintenance, the 318871 serves as a direct drop-in for the obsolete Greenheck 301833. It features a resilient base for vibration dampening and sleeve bearings that provide smooth, quiet rotation in centrifugal fan assemblies and power roof ventilators. With a full load amperage of 3.0 Amps, this single-phase motor delivers the torque required for consistent airflow without excessive energy consumption.

• Dual Shaft Design: Features a 4.25-inch shaft length for versatile blower wheel mounting in various equipment configurations.
• Thermal Overload Protection: Automatic reset feature protects the windings from high-temperature failure.
• Direct OEM Compatibility: Ensures identical mounting points and electrical specs for Greenheck fan motor replacement.
• Sleeve Bearing Construction: Optimized for longevity and reduced mechanical noise in quiet-zone applications.
• Industrial Build Quality: Robust steel frame construction resists corrosion and provides structural integrity in high-static environments.

Common Questions

Is this a direct replacement for the Greenheck 301833 model?
Yes, the 318871 is the official replacement for the discontinued 301833, matching its 115V input and 1/6 HP rating while providing improved efficiency at 1075 RPM.

Does this motor work with variable speed controllers?
This is a standard PSC motor. While it is designed for single-speed operation at 1075 RPM, it is compatible with many standard speed control devices used in Greenheck ventilation setups; always verify controller voltage and amperage limits.

What are the shaft specifications for blower wheel fitting?
The motor utilizes a dual-shaft setup with a 0.5-inch diameter, allowing for flexible positioning of a 4.25-inch extended shaft to match specific housing depths.
