Century Motors 669 Motor

The Century Motors 669 is a high-performance, multi-horsepower PSC condenser fan motor engineered for light commercial and residential air conditioning applications. Designed with the versatility that contractors need, this direct replacement for Fasco D290 features a 42 Nema frame size and functions across 1/10, 1/15, 1/25, and 1/35 HP ratings. This 115V single phase motor operates at a 1075 RPM synchronous speed with four separate speed taps, allowing for precise airflow tuning based on system static pressure. Built with an open air over (OAO) enclosure and durable sleeve bearings, the unit ensures optimal heat dissipation during continuous duty. The 1/2" x 8 1/2" flatted shaft and reversible rotation capability make it a universal solution for HVAC motor replacement in fan coils and blower units. For peak operational efficiency, a 5 MFD 370V capacitor is required to maintain the permanent split capacitor start and run torque.

• Broad Compatibility: Serving as a universal HVAC blower motor, the 669 covers four horsepower ratings, reducing the need to carry multiple SKUs on the truck.
• Technical Versatility: Features a reversible rotation design and multiple speeds (1.7 to 0.62 Amps) to match specific OEM requirements.
• Robust Construction: The NEMA 42 frame and rolled steel body provide a compact footprint for tight air handler cabinets without sacrificing torque.
• Efficient Performance: Uses a Permanent Split Capacitor (PSC) design to lower energy consumption compared to shaded pole alternatives.

Can the Century 669 replace a Fasco D290?
Yes, the 669 is the direct industry cross-reference for the Fasco D290, matching its frame, voltage, and multi-tap speed configurations.

What capacitor is required for this motor?
This motor requires a 5 MFD / 370 VAC capacitor for proper PSC motor operation. Using an incorrectly rated capacitor can lead to overheating or winding failure.

Is this motor suitable for outdoor condenser units?
The 669 features an Open Air Over (OAO) enclosure, meaning it relies on the moving airstream for cooling and is best suited for indoor fan coils or air handlers rather than exposed outdoor condensing units.
