1. Copper core motor, strong wind, fast heat dissipation, safe and durable 2. Low noise, long life, low energy consumption, large air volume, stable operation, fast start 3. 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 noise 4. The metal shell is strong and durable, with the characteristics of anti-drop, corrosion resistance, oxidation resistance, high temperature resistance, etc.; it can be used in high temperature environment for a long time, with stable performance 5. 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 consumption 6. Fan blade material: black painted metal 7. Bearing: double ball/oil 8. Number of blades: 7 9. Wind pressure: 4.0/5.5 MMH20 10. Air volume: 0.49/0.60 cubic meters per minute 11. Noise: 29/33DB 12. Use scenarios: industrial equipment, household appliances, medical equipment, etc. 13. Applicable temperature: -10 to 60 degrees Celsius 14. Voltage: 110V/220V/380V 15. Frequency: 50/60HZ 16. Current: 0.07A 17. Power: 13/11W 18. Speed: 2300/2750RPM 19. Dimensions: 80 x 80 x 25MM 20. Weight: 125G Difference: - 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 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
