Greenheck 318873 Motor

Greenheck 318873 Motor

The Greenheck 318873 Motor is a high-performance 115V 1100RPM 1PH Double Shaft replacement designed specifically for heavy-duty HVACR ventilation systems. This OEM Greenheck replacement motor features a dual-shaft configuration, allowing for the simultaneous operation of multiple fan assemblies or specialized blower wheels common in Greenheck exhaust and supply fans. As a PSC (Permanent Split Capacitor) motor, it provides the high torque and operational efficiency required for continuous-duty cycles in commercial environments. Built with a NEMA 42 frame and a rigid base mount, it ensures stable, low-vibration performance even at its full 1100 RPM rated speed.

Engineered for technical reliability, this 1/6 HP motor utilizes an Open Dripproof (ODP) enclosure to facilitate maximum heat dissipation while protecting internal windings from vertical moisture entry. The sleeve bearing design and Class B insulation rating make this 318873 motor an industry standard for maintaining optimal static pressure and airflow in rooftop units (RTUs) and fan coil units. Contractors often specify this part for its precise 3.3 Amp draw and built-in automatic thermal overload protection, which prevents field failures during voltage fluctuations or high-ambient operating conditions.

Key Benefits:
  • Dual shaft versatility: Enables concurrent rotation for diverse fan and blower configurations.
  • Enhanced thermal protection: Features automatic internal overload reset to prevent winding burnout.
  • OEM Precision: Direct drop-in compatibility for Fasco 7190-2773 and Greenheck 304970 models.
  • Rugged Housing: Rigid base and 42-frame construction minimize mechanical resonance and wear.
  • Optimized Efficiency: 115V single-phase 60Hz PSC motor delivers consistent performance with a lower amperage draw.
Common Questions:

What are the specific shaft dimensions for the 318873 motor?
This motor typically features dual shafts measuring 4-1/2" long with a 3/8" diameter, ensuring compatibility with standard Greenheck fan wheels and hubs.

Is this motor reversible in the field?
No, this specific model is typically factory-set for CWLE (Clockwise Lead End) rotation. Always verify your specific fan blade Pitch and lead end rotation before installation.

Can I use a variable frequency drive (VFD) with this PSC motor?
PSC motors like the 318873 are generally designed for single-speed or multi-tap applications. Consult the wiring diagram for speed control options; using a VFD on a standard PSC motor may cause overheating.
