Q: What are the advantages of ball bearing fans over sleeve bearing fans? A: Ball bearing fans are typically less prone to wear and tear than sleeve bearing, which makes them ideal for a longer service life. They are also able to operate in higher temperatures, and in any orientation. However, they are less rugged and can be more easily disrupted by impact, and tend to be noisier than their sleeve bearing counterparts. Q: Is the fan easy to operate? A:With completely integrated electronic communication, the fans require little input from the user to operate. Q: Is the fan durable? A: 3400N series ball bearing axial fans are constructed from glass fibre reinforced plastic, and are protected against a degree of particle ingress as standard.
