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.
Preventivemaintenance 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.
