The device adopts the specially developed HPM adsorption materials to make into the FH rectangle deep-seated,high-precision filtration system.In processing  the hydraulic oil ,turbine oil,Lubricating oil and other oil products,the first procedure is  coalescence-separation for the removal of large  amount of moisture ;Then through the vacuum evaporation system,deep traces of moisture removal is done and followed by high-precision filtration,thereby enabling oil to be in the renewable use by purification.

This device perfectly combines rapid removal of  a  large amount of moisture in the coalescence-separation with vacuum evaporation for trace moisture in-depth removel ,being provided with  remarkable festures in rapid high efficient dehydration .It is specificationlly applicable to lubrication system and the hydraulic system with large capacity of the fuel tank and the system flow,and with more moisture ingress and particle pollutants in power plants,petrochemical and metallurgical industries.
