Which maintenance type is planned and routinely performed to extend equipment life?

Preventive maintenance is the type of maintenance that is planned and routinely performed to extend the life of equipment. This approach involves scheduled inspections, servicing, and repairs designed to prevent unexpected equipment failures. By addressing potential issues before they become serious problems, preventive maintenance helps to ensure that equipment operates efficiently and reliably over time. Regular maintenance tasks might include changing filters, lubricating moving parts, and tightening loose components, all aimed at enhancing longevity and performance.

In contrast, other options like deferred maintenance refer to necessary repairs that are postponed, often leading to more significant issues down the line. Curative maintenance typically addresses existing problems rather than preventing future ones, while routine maintenance is a broader category that may include both preventive and corrective actions but does not exclusively focus on extending equipment life as preventive maintenance does.
