Centrifugal fans, with their moving parts and sometimes heavy-duty air processing, require regular fan maintenance in industrial applications. You might need to clean it, you might need to balance it, you might need to repair a part, or even retrofit the fan. At some point, you’ll need access to work on the wheel and shaft. If you’re not sure you’ll be able to get into the access doors in your application, split housings might just save the day.

A Closer Look at Horizontal Split Housings

Split housings allow you to remove your ductwork off the top of the fan, lift the top of the housing straight up, and either get in to do the work or remove the wheel and shaft to work on them and put them back in. This is much easier and faster than removing and reinstalling the whole fan.

There are multiple ways you can split your housing depending on how your fan will be situated relative to the ductwork. A horizontally-split fan housing is a common option. The bolted-down bottom half of the housing will meet the top half of the housing with a gasket connecting the two flanges. To work on the wheel and shaft, all you need to do is remove the bolts in the middle, lift straight up, and get right to it.
