XIN RUI FENG 12V Ball Bearing 6cm Quiet DC Cooling Fan

1. Copper core motor, strong wind, fast heat dissipation, safe and durable2. Low noise, long life, low energy consumption, large air volume, stable operation, fast start3. High-strength and high-toughness fan blade, one-time injection molding, long service life, not easy to deform and break; not only has strong wind power but also effectively reduces noise4. The outer frame is made of high-quality PVC plastic, which can withstand high temperature and withstand physical impact to a certain extent, effectively protecting the motor and fan blades5. The use of pure copper coils can effectively reduce the operating temperature and current of the fan, high temperature resistance, greatly improve its operating stability and low energy consumption6. Blade material: PVC plastic7. Applicable temperature: -10 to 60 degrees Celsius8. Use scenarios: industrial equipment, household appliances, medical equipment, etc.9. Motor power: 1.92/3.12W10. Air volume: 20.3/25.4cfm11. Bearing: double ball/oil12. Lifespan: 60000 hours13. Current: 0.16/0.13A14. Voltage: 5/12/24V15. Speed: 5000/400RPM16. Dimensions: 60 x 60 x 25MMDifference:- Ball bearing: the model is generally indicated by B; there are several tiny steel balls in the bearing that rotate around the axis in the form of rolling friction, so the friction force is small and there is no oil leakage. Features: long life, suitable for high speed fans- Oil-impregnated bearing: the model is generally indicated by S; it adopts a sliding friction sleeve, and the shaft of the fan blade uses lubricating oil in the sleeve as a lubricant and a drag reducer. Features: Resistance to external impact, low noise
