1. All-copper movement, strong air flow, durable, high speed stability
2. Pure copper wire movement, high temperature resistance, stable operation and long life
3. High-strength and thickened fan blades. The fan blades adopt a one-time injection molding process, which is not easy to deform and break. The unique design of the fan blades makes the contact area larger, the air volume is larger, and the heat dissipation effect is good.
4. The outer frame is made of PVC plastic, which is resistant to high temperature and can withstand physical impact to a certain extent, effectively protecting the motor and fan blades
5. Scope of application: heat dissipation of mechanical equipment
6. Applicable temperature: -10 to 60 degrees Celsius
7. Bearing: double ball/oil
8. Motor power: 12V: 1.56W, 24V: 3.84W
9. Voltage: 5V/12V/24V
10. Current: 12V: 0.13A, 24V: 0.16A
11. Air volume: 12V: 9CFM, 24V: 9.1CFM
12. Speed: 12V: 4500R/MIN, 24V: 5000R/MIN
13. Material: PVC plastic
14. Product life: 60000 hours
15. Size: 50x50x10MM

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
