Filter Units

All lubrication and hydraulic fluids should be filtered before they are put into service. New fluid is not necessarily ‘clean’ fluid. Contamination such as water and particulate can be introduced during processing, handling and storage. This contamination can therefore make the new fluid unfit for use.  This is indeed the case with hydraulic equipment such as proportional and servo valves which require ISO cleanliness levels to 17/15/12 and 16/14/11 respectively.
