220V AC Cooling Fan you will not get the victory today

1, "220V AC Cooling Fan" high speed and acceleration - dn value can operate under conditions of over 3 million, and the skid, wear and heat can be reduced;
2,12V DC fan long life, resistance to wear - full ceramic bearing fatigue life expected 10-50 times longer than steel bearings, hybrid ceramic bearings, life expectancy is higher than the all-steel bearing life is about 3-5 times;
3, "220V AC Cooling Fan" minimal lubrication required - a low friction coefficient of the ceramic material, ceramic bearings lubricated by oil, the lubricating oil in the case of thinning or lean, the lubricating ability is still lower than the steel bearings commonly used conventional lubricants;
4, abrasion - because the ceramic material is inert material, it is more resistant to corrosion and wear;
5, rigidity - by the elastic modulus of the ceramic material is high, its larger rigidity than the ordinary steel bearings 15-20%;
6, "220V AC Cooling Fan" temperature - Full ceramic bearings can operate in temperatures above 500 ℃.
