220V Cooling Fan bearing technology

"220V Cooling Fan" bearing technology for fan performance, noise, life plays an important and decisive role, must be observed when the actual purchase fan. Usually based on performance, noise, life and price requirements into account four aspects:
1. The performance is not high, low noise, low prices, oil-bearing is the only option, but life is short, noise may be used for a period of time increases, the need to do maintenance or replacement of psychological preparation.
2. "220V Cooling Fan" powerful performance, long life, price is not high, the ball bearing is the best choice, but need to put up a large noise generated when their work.
3. Performance and noise are no special requirements, but hopefully long life, price is not high, to Fu, Hypro bearing oil bearing improved are worth considering.
4. "220V Cooling Fan" good performance, low noise, long life, so we can not make further demands on the price, as long as adequate funding, hydraulics, precision ceramic bearing technology and other features can be included in the selection range.
5. Quiet and demanding life, magnetic bearings is the only choice, but poor performance, price is too high.
