220V 38W 15cm Roller Chassis Electrical Cabinet Shaft Oil Bearing 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 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 performance5.

Frequency: 50/60HZ18. Wind pressure: 14MMH2019. Size: 150 x 150 x 50MM20. Weight: 800GDifference:- 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
