Following the development of hydraulic industry for high request increasing working reliability is very importance. At present about 70% breakdowns be caused by contaminants. It will confirm that the machine will be damaged by she petroleum product's admixtures. To control the oil cleanliness besides the oil filter. The hand cart will be filtered the outcoming oil liquid that is injectell into the system and raised the oil cleanliness grades of oil products.

Be designed and manuafactured the precision filtering hand cart features high accuracy, function reliability, compact structure, beautiful look, nimble performance and easy maintenance. The degree of filtration is rated 40.30.20.10.5.3.1 um. According to the customer's request for electing. It is devided into hydraulic system, static pressure system, lubrication system and vatiour oil for filtering with a period time, and retrieved the dirty oil for economization with no influence of oil targets.
