Planned Preventive Maintenance (PPM) is a proactive approach to maintaining equipment and systems. It involves regularly scheduled inspections, tests, servicing, and replacements to ensure that equipment and systems are operating properly and efficiently. PPM is designed to prevent breakdowns and minimize downtime, while also reducing the need for emergency repairs. PPM also helps to identify potential problems before they become serious and costly. This type of maintenance is important for any business that relies on its equipment and systems to operate, as it can help to reduce the risk of unexpected downtime and expensive repairs. Additionally, PPM can help to extend the life of equipment and systems, saving businesses money in the long run.
