The oil filter is used to filter lubricating oil
Thread Content
When the compressor lubricant changes color and its particulate content increases, do the properties of the lubricant change after it has been filtered by an oil filter? Can it still be used?
It depends on what kinds of magazines are inside; particles can be removed using a filter plate type oil filter, while moisture and the like can be removed using a vacuum oil filter
Today’s online oil purifiers generally combine the function of filtering out solid particles with that of removing water. In general, there is no problem using them continuedly; the oil that has been processed will definitely be of better quality than before, but it is still necessary to conduct inspections as per the procedures.
The color change can be due to pigment changes that occur during normal use of the oil, as well as color changes caused by impurity particles； A change in color does not mean the oil can no longer be used ； It is necessary to conduct tests to determine whether the oil can still be used; if all other parameters are within the acceptable range and the impurity particles have been filtered out, then it can be used.
Filtering particles and removing water are the first steps; acidity levels also need to be checked. It is recommended to replace the lubricating oil in a timely manner according to the equipment’s requirements. There are many fake oils available on the market, so be careful!
Is color change an indication that the lubricant has deteriorated? ? Filtering is simply to remove impurities and moisture
Tests and analyses need to be carried out to check parameters such as viscosity and acid value
High in moisture, the filter paper is soft and plump, white in color, with water stains on the edges.
