BACK PAGE BASICS If your facility has a centralized lube room, set an overall cleanliness target for each oil type. When establishing these targets, begin with the most sensitive machine component using each oil and work through the same process for each machine. By better understanding the cleanliness code, setting appropriate targets and closely monitoring your particle counts, you can determine how dirty or clean your oil is, which should then help you achieve your overall reliability goals. Once you have set your cleanliness targets, take a stepped approach to cleaning your oils. Starting with a high-efficiency filter at a small micron level would be expensive. Instead, slowly progress to smaller micron filters over time. When you reach your goal, you can then maintain this cleanliness level with higher efficiency filters.
