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.
