Vibration analysis is a powerful tool for predictive maintenance when deployed regularly (and early in the compressor's life cycle). Every component from the ball bearings to the gears and rotors has its own frequency that is detectable when monitored properly. By reviewing the frequency readings and studying the peaks and valleys on the vibration analysis graph, analysts can pinpoint an issue before it impacts the compressed air system helping to prevent downtime - and headaches.
