Reasons for Measuring a Fan 

Generally, there are two reasons to measure a centrifugal fan – the user wants to retrofit the fan (or parts) or replace it with a new fan. In either case, accurate measurements are critical to replicating the system currently in place, especially if no drawing is available. If possible, separate or isolate the fan from the system to access key measurement points. If duct work on the inlet or outlet is in the way, this could impact measurement accuracy. 

Our work at AirPro is not always about designing new fans; we often build replacement parts for all fan brands and send field service support teams to oversee installation and ensure the fans are ready for operation. We recently helped a minerals facility when their fan was damaged during operation. Our application engineers recommended replacement of the fan wheel and inlet cone and then our manufacturing team expedited production to provide the fastest delivery possible.
