  • Page 46: Clean Working Practices

    6.5 Clean Working Practices The majority of hydraulic systems require cleanliness levels below 40 micron - the threshold of human eyesight. When analysing particles down to levels of 4um, 6um & 14um you are talking about objects of a cellular/bacterial size. This creates various challenges, and is starting to drive better and cleaner working practices in industry.
