The Hydraulic Filtration System is a mechanical separation procedure with the aim of separating a suspension into the components solid matter (contamination) and fluids. When filtration concept is defined, system and machine-specific operating conditions must be taken into consideration. The hydraulic filter is a component used by hydraulic systems to continuously remove contaminants in the hydraulic oil. When a new and recently cleaned filter element is fitted in the housing, the tell-tale indicator will indicate that it is clean. Hydraulic Filtration is very efficient.
