Greenheck 302529 Motor

The Greenheck 302529 Motor is a high-performance 1/25 HP replacement motor designed for demanding ventilation applications. This 115V single-phase motor features a shaded pole design, engineered for reliability in Greenheck exhaust fans and inline blowers. With its 3-speed capability (1550/1300/1050 RPM) and 1.2 Amp draw, it provides versatile airflow control while maintaining energy efficiency. Built for longevity, the 302529 motor utilizes sleeve bearings and an AutoOverload thermal protection system to prevent overheating during continuous operation. The 5/16 inch diameter shaft with a flat surface ensures a secure fit for standard fan wheels, while the extended thru-bolt mount configuration simplifies installation for field technicians. This unit serves as a direct OEM replacement motor, superseding legacy parts like the 300451 and Fasco 71635376. Its CCW rotation (facing the shaft) is optimized for centrifugal and axial fan designs, ensuring peak static pressure performance in commercial HVAC systems.

Key Benefits:

• Multi-Speed Versatility: 3-speed operation (1050/1300/1550 RPM) allows for precise airflow adjustment based on system requirements.
• Industrial Durability: Features a robust construction with an open drip-proof (ODP) design and Class B insulation for consistent performance.
• Simplified Maintenance: Thermal automatic reset overload protection minimizes downtime by protecting the windings from electrical stress.
• True OEM Compatibility: Engineered as a direct drop-in for Greenheck model 302529, ensuring shaft alignment and mounting hole precision.
• Efficient Power Consumption: Operating at just 18.8 watts, this motor provides necessary torque without excessive energy costs.

Common Questions:

Does this motor include the mounting hardware?
The motor features an extended thru-bolt mount (4 studs on the shaft end), allowing you to secure it using existing brackets in Greenheck housings. Check your specific fan model to see if additional vibration isolators are needed.

How do I confirm the rotation for my fan wheel?
The 302529 motor is rated for CCWSE (Counter-Clockwise Shaft End) rotation. Always verify the pitch of your fan blades before installation to ensure the air moves in the intended direction.

Can this motor replace a single-speed unit?
Yes, provided the frame size and electrical specs match. You can wire it for a single high speed or utilize a selector switch to take advantage of the 3-speed leads for balanced ventilation.
