Belts, Pulleys, Shafts, & Bearings
Several base arrangements offered by Jan-Air require the use of belts, pulleys, shafts, and bearings. Belt driven units are often used when the wheel must spin at a specific RPM not offered by motor manufactures and also in high-temperature applications to prevent the motor from overheating due to the heat transfer through the shaft. Often these types of applications will also incorporate a heat slinger.

Jan-Air Custom Inlet Boxes

Custom inlet boxes are used in specific applications to make ductwork transitions and arragemnents easier. The custom inlet box shown below is used to make the scroll housing arragemnent more similar to an inline unit. Please let us know if your application requires a modified inlet or inlet box.
