Predictive maintenance looks for signs of trouble, intending to prevent costly repairs down the line. For example, moisture leaks, air bypasses, pressure fluctuations, energy usage fluctuations, housing cracks and motor stress sounds are all predictors that a problem might be developing in an operating system. Equipment downtime and repair time are reduced by noticing and preparing for part failures or needed change-outs in advance.

Preventive maintenance is the regular, prescheduled service of a system or piece of equipment. It is intended to maintain the equipment at peak operating efficiency, often according to the manufacturer’s specifications. A good preventive maintenance program includes regular inspections to identify signs of developing problems and prepare for them - i.e., predictive maintenance.

With air filtration, preventive maintenance typically includes scheduled filter cleanings or change-outs, gasket replacements, airflow measurements and pressure drop tests.
