Greenheck 329315 Motor

The Greenheck 329315 Motor is a precision-engineered 115V direct drive motor designed specifically for integration into commercial exhaust fans and ventilation systems. Operating at 1/4 HP with a rated speed of 830 RPM, this single-phase power unit provides the necessary torque for consistent airflow in high-static pressure environments. Built with a totally enclosed air over (TEAO) enclosure, the replacement fan motor prevents dust and moisture ingress, ensuring internal components remain protected during continuous operation. As an OEM Greenheck part, it offers exact physical and electrical compatibility, eliminating the mounting challenges often encountered with generic alternatives. This motor is commonly utilized in G and GB series centrifugal roof exhausters, maintaining the factory-specified performance curves required for proper building pressure control. Its permanent split capacitor (PSC) design enhances electrical efficiency while reducing the start-up current draw across the circuit.

• Direct Drive Efficiency: Eliminates belt maintenance and power loss, providing a streamlined mechanical connection for HVAC ventilation systems.
• TEAO Enclosure: Designed to withstand the steady flow of air through the motor, ensuring thermal stability in Greenheck exhaust fan applications.
• Technical Compatibility: Features a standardized frame size and shaft diameter for seamless field replacement of the Greenheck 329315.
• Resilient Mounting: Specific mounting configurations reduce vibration transfer and structural noise during high-demand operation.

What are the wiring requirements for the Greenheck 329315?
This motor operates on a standard 115V single-phase circuit. Always refer to the specific wiring diagram on the motor housing to ensure proper capacitor integration and rotation direction.

Is the 329315 motor suitable for variable speed control?
Most PSC motors like the 329315 can be used with compatible solid-state speed controllers, provided they are rated for the motor's amperage and don't cause excessive motor hum or overheating.

Why is the 830 RPM rating critical for this fan motor?
The 830 RPM specification is matched to the fan blade's pitch and diameter. Deviating from this RPM can result in motor overloading or a failure to meet the required CFM (cubic feet per minute) for the space.
