Belt Driven Blowers: Why do others fail?

Idler Systems

Belt driven blowers have been know to fail primarily due to the amount of tension on the belts (up to 300 foot-pounds of tension is required to help belt slippage.) For this reason some Blower manufacturers developed an ‘Automatic Belt Tensioner’ system. However, rather than improve the situation, as well as regular belt failures, users now have the added problem of the Belt Tensioner failing as well.

The major advantage of installing an ACI EP10 is that they only have only 110 foot-pounds of tension. This means that both belts last far longer and that there is no need for an idler arm.

Belt Load

Again, a number of belt driven blower manufacturers have the belts cantilevered i.e. on the pulley the belt rides with tremendous axial loads on the drive shaft. Due to ACI innovative design, the EP10 has its belt-load between the bearings, therefore eliminating the cantilever effect.

Bearings

Bearings determine how long the blower can rotate without seizing up. Instead of conventional ABEC standard bearings, the EP10 uses precision matched pairs of sealed, ceramic hybrid bearings.
