FAQ:

1. What's the difference between the sleeve and ball bearing fan?

The ball bearing brand was NSK bearing imported from Japan.

The warranty for ball bearing fan is 30,000 hours but sleeve bearing just 10,000 hours.

Ball bearing has 5-8 years lifetime,sleeve bearing has 2-3 years lifetime.

Ball bearing fan noise level won't change for a long time term,but sleeve bearing fan noise level will grown as time goes on.

Sleeve bearing is cheaper than ball bearing fans.

 

2. What kind of function can we choose for fan?

Optional function :Auto-restart ,Speed detection,Stppage Alarm,Waterproof(IP55-IP68 optional), PWM function ,Temperature control etc.

 

3. How long can your wire length be ?

The wire length and terminal could be customized as your request. We just need the picture of connector and rank of wires for confirm.(Default wire length is 200mm)
