Marley Engineered Products 3900-2033-000 Motor

The Marley Engineered Products 3900-2033-000 Motor is a high-performance 1/8 HP replacement fan motor specifically engineered for Marley, Berko, and QMark cabinet unit heaters and industrial air handlers. This 208-240V permanent split capacitor motor operates at a nominal 1550 RPM, providing the consistent torque required for high-static HVAC environments. Featuring a double-shaft design with 1/2-inch diameters, it allows for versatile blower wheel mounting in dual-fan configurations. The rugged steel frame and aluminum flange are built for continuous duty (Type OAO), ensuring heat dissipation in ambient temperatures up to 40°C.

For successful field integration, verify your HVAC blower motor specifications. This unit is rated for 1.6 Amps and functions on both 50Hz and 60Hz frequencies. Note that for 208V applications, a 5 MFD/370 VAC capacitor is typically required, while 240V setups utilize a 3 MFD/370 VAC capacitor (sold separately). The 3900-2033-000 serves as a direct cross-reference for DE2F098 and DE2E202, maintaining OEM airflow standards across multi-speed heater cycles.

• Broad Compatibility: Standardized fit for Marley OEM motor replacements in CUH series and industrial fan motors.
• Dual-Shaft Versatility: 6-1/4" x 1/2" x 6-1/4" shaft dimensions facilitate double shaft motor installations in commercial air movers.
• Thermal Protection: Class B insulation and open air-over construction support long-term reliability in 208-240V motor applications.
• Precision Speed Control: Maintains 1550 RPM to optimize cabinet unit heater efficiency and static pressure performance.

Common Questions

Is this motor compatible with 120V systems?
No, this motor is strictly rated for 208-240V. Operating it on 120V will cause failure to start or rapid overheating.

Does this unit include the run capacitor?
No, the capacitor is not included. You must match the capacitor MFD rating to your specific supply voltage (5 MFD for 208V or 3 MFD for 240V) to prevent winding damage.

What is the rotation direction?
The 3900-2033-000 features a CCWLE (Counter-Clockwise Lead End) rotation, which is standard for most Marley engineered centrifugal fan assemblies.
