Greenheck 304287 Motor
The Greenheck 304287 Motor is a high-performance direct drive replacement motor specifically engineered for commercial and industrial ventilation systems. This 1/6 HP HVAC motor operates at 1725 RPM, delivering the consistent torque required for centrifugal roof fans and air handling equipment. Built on a standard 48Z frame with a resilient base, it facilitates a secure, low-vibration fit in existing Greenheck fan assemblies. Operating on a single-phase 115V power supply, this unit features Counter-Clockwise (CCW) rotation (viewed from the shaft end), which is critical for maintaining correct airflow direction in exhaust and supply applications. The Open Drip Proof (ODP) enclosure rating ensures internal components remain protected from falling moisture and debris in relatively clean indoor environments. As an OEM Greenheck replacement part, it meets the exact specifications of the original equipment, ensuring seamless integration and reliable field performance.
Key Benefits- NEMA 48Z Frame: Features a specialized mounting configuration for precise alignment with Greenheck direct-drive fan housings.
- ODP Enclosure: Optimized for indoor ventilation where air is relatively clean and dry, maximizing motor life through efficient cooling.
- High Torque Output: The 1725 RPM 4-pole design provides the necessary starting torque for centrifugal blowers and fans.
- Thermal Overload Protection: Includes automatic reset thermal protection to prevent motor burnout during temporary over-current conditions.
- Drop-in Compatibility: Exact electrical and mechanical match for part number 304287, reducing downtime during maintenance cycles.
Is the Greenheck 304287 motor compatible with variable frequency drives (VFDs)?
This specific 115V single-phase motor is typically designed for constant speed operation. For applications requiring speed modulation, verify the controller's compatibility with single-phase induction motors to avoid winding damage.
How do I confirm the rotation of this motor?
The 304287 is rated for CCW rotation. In the HVAC industry, this is standardly determined by viewing the motor from the lead or shaft end as specified in the submittal; ensure your fan wheel requires a counter-clockwise drive to maintain static pressure performance.
Can this motor be used in outdoor exposed locations?
Because this is an Open Drip Proof (ODP) motor, it should be used within a protected fan housing or weather cover. It is not suitable for direct exposure to rain or heavy wash-down environments without additional shielding.
