Greenheck 304742 Motor
The Greenheck 304742 Motor is a high-performance 1/3 HP HVAC replacement motor engineered for demanding commercial and industrial ventilation. Operating at 115V with a standard 1725 RPM, this single phase 60Hz motor is a critical component for maintaining optimal airflow in Greenheck exhaust fans and centrifugal blowers. Built on a NEMA 48 frame with a 0.5-inch shaft diameter, it features a resilient base (cradle mount) to significantly reduce vibration transfer through the fan housing, extending the life of the drive assembly. The Open Dripproof (ODP) enclosure is designed for clean, dry indoor environments, providing a balance of energy-efficient air movement and reliable steady-state performance. As a genuine OEM Greenheck part, this motor ensures precise mechanical compatibility and electrical alignment with factory specifications, preventing the common overheating issues associated with non-spec substitutes in high-static pressure systems.
Key Benefits- Direct OEM Compatibility: Verified as a drop-in replacement for Greenheck 304742, ensuring shaft alignment and mounting hole precision for 48 frame motors.
- Vibration Dampening: Equipped with a resilient base that isolates motor harmonics, protecting delicate ductwork and improving workplace acoustics.
- Optimized Performance: Delivering 1/3 HP at 1725 RPM, it provides the exact torque profile required for heavy-duty exhaust blowers and air handling units.
- Industrial Durability: Constructed with rolled steel housing and internal thermal protection to handle continuous duty cycles in commercial kitchens and warehouses.
What is the frame size and shaft dimension for this motor?
The Greenheck 304742 utilizes a 48 frame with a resilient base. The output shaft has a 1/2-inch (0.5") diameter, standard for this horsepower class in ventilation systems.
Can this motor be used with a variable frequency drive (VFD)?
This is an AC induction motor designed for 115V single-phase operation. While it provides reliable single-speed performance, always verify your specific controller's compatibility with single-phase induction motors before installation.
Is this motor suitable for outdoor roof-mounted fans?
This model features an Open Dripproof (ODP) enclosure. It is best suited for indoor applications or within weathertight fan housings where it is protected from direct moisture and environmental debris.
