Greenheck 301772 Motor

The Greenheck 301772 Motor is a high-performance direct drive blower motor specifically engineered for continuous duty in industrial and commercial ventilation systems. This 0.167 HP HVAC replacement motor operates on a standard 115V single-phase power supply at 60Hz, pulling approximately 2.7 Full Load Amps. With a synchronous speed of 1200 RPM and a NEMA 48 frame, it serves as a precise OEM solution for Greenheck roof-mounted exhaust fans and inline blowers. The Open Drip Proof (ODP) enclosure ensures maximum airflow for cooling internal windings while protecting against vertical moisture ingress. Built with a rigid base mount and a standard 0.5-inch shaft diameter, it facilitates a secure, vibration-resistant installation for mechanical contractors. Its automatic thermal overload protection prevents winding failure during restricted airflow conditions, ensuring system longevity in rigorous rooftop applications without the need for manual resets.

• OEM Compatibility: Precision Greenheck 301772 replacement ensures exact fitment for 48-frame blower assemblies.
• Enhanced Cooling: The Open Drip Proof housing manages heat dissipation effectively during extended run cycles.
• Integrated Safety: Features internal auto-overload protection to safeguard the motor against voltage spikes or mechanical binding.
• Rugged Construction: Rolled steel frame and robust 1/6 HP output provide the torque necessary for centrifugal fan loads.
• Reliable Performance: 1200 RPM operation maintains consistent CFM ratings across static pressure variations.

What are the primary applications for this Greenheck motor?
This motor is typically found in Greenheck centrifugal roof exhausters, sidewall fans, and small inline cabinets where a 1200 RPM operating speed is required to meet specific airflow balancing specs.

Can I use this to replace a PSC motor with different capacitor specs?
Technicians should verify the nameplate; as a dedicated 115V 1200 RPM motor, it is designed to match the original electrical footprint. Always check your wiring diagram to confirm lead wire configurations before mounting.

Does the 48-frame size include standard mounting?
Yes, the NEMA 48 frame features a standard rigid base. For contractors replacing older un-housed units, verify the 0.5-inch shaft diameter matches the existing blower wheel bore to avoid field modifications.
