FAN COND 300/400V

Appliance Maintenance: Premium Yellow CBB61 Axial Fan Capacitor Series — High-Stability Motor Start & Run Condensers

Restore or maintain the peak rotational speed of your cooling hardware with our Premium Yellow Axial Fan Capacitor (Condenser) Series. Engineered specifically for AC electric motors, these high-grade metallized polypropylene film capacitors provide the stable phase-shift required to start and run electric fans efficiently. If your ceiling fan, stand fan, or exhaust fan is spinning slowly, humming without rotating, or failing to start, a degraded condenser is the most common culprit.

As clearly visible in the file FAN COND 300400V.png, these capacitors feature a distinct cylindrical axial design with flexible wire leads extending from each end, allowing for seamless inline soldering or splicing. Finished in a high-visibility vibrant yellow protective outer sleeve, each unit is clearly laser-printed with its microfarad ($\mu\text$) rating, voltage capacity, and operating tolerance to ensure a precise match during replacement.

Key Performance Features

• High-Stability Motor Performance: Delivers a reliable capacitance path to optimize motor torque, ensuring smooth, vibration-free fan operation.

• Premium Axial Lead Configuration: Designed with flexible inline wire leads on opposite ends, making it exceptionally easy to install in tight motor housings or narrow wiring cavities.

• Self-Healing Metallized Film: Built with advanced internal dielectric layers that offer exceptional over-voltage resilience and an extended operational lifespan.

• Strict $\pm5\%$ Capacitance Tolerance: Precision-calibrated tolerance ensures your replacement conforms exactly to electrical design guidelines for uniform power delivery.

• Excellent Heat & Moisture Insulation: Encased in a flame-retardant, high-temperature resistant yellow casing engineered to handle ambient environment stresses behind motor enclosures.

Typical Applications

This axial fan condenser series is the ideal solution for:

• Ceiling Fan Speed Repair: Overcoming slow rotation speeds or starting failures in standard domestic and commercial ceiling fans.

• Exhaust & Blower Systems: Servicing kitchen ventilation hoods, bathroom extractor units, and warehouse ventilation rigs.

• Stand & Wall Fans: Replacing worn-out stock condensers in oscillating office fans, industrial floor fans, and misting hardware.

• HVAC Maintenance Support: Serving as a reliable, high-grade stock part for local electrical contractors, HVAC repair technicians, and workshop spares.

3 Top Customer Questions & Concerns ‍

Can I replace my broken capacitor with a much higher microfarad ($\mu\text$) rating to make my fan spin faster?

No! You should always try to match the original UF rating as closely as possible (ideally a 100% exact match). Installing a capacitor with a significantly higher rating will over-saturate the motor windings with current, causing the fan motor to overheat, hum loudly, and drastically shorten its lifespan or burn out completely.

Does it matter which wire connects to Live or Neutral?

Not at all. These CBB61-type film fan condensers are non-polar AC capacitors. This means they do not have a positive or negative terminal. You can safely connect either of the two axial wire leads to your source line and the other to the start winding loop without worrying about orientation errors.

Can I use a 400V capacitor to replace a 300V capacitor if the UF value is identical?

Yes! You can always safely upgrade to a higher Voltage (V) rating (e.g., using a 400V AC unit to replace a 300V AC unit) as long as the microfarad UF capacity matches perfectly. The voltage rating indicates the absolute maximum electrical stress the insulation can handle; a higher voltage rating simply offers extra safety headroom. Never downgrade to a lower voltage rating than the original.
