Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

There are many advantages that vertical pumps provide over horizontally mounted pumps and when they operate properly they generally provide many years of reliable, maintenance free operation. However, in almost any plant with a large inventory of vertical pumps they will have one or more of these pumps that are considered “bad actors”...
