Use this checklist as a quick reference to keep your fans in tip-top operating order. Typically, fans provide years of trouble-free operation with relatively minimal maintenance. However, this high reliability can lead to a false sense of security, resulting in maintenance neglect and eventual failure. Due to their prominence within process systems -- without the fan operating, the system shuts down -- fans need to remain high on the maintenance activity list.
Most fan maintenance activities center on cleaning housings and fan blades, lubricating and checking seals, adjusting belts, checking bearings and structural members, and tracking vibration.
