ABSTRACT:
A filter apparatus, particularly for filtering coolant/lubricant from a machining, including a filter tank having an inlet for the liquid to be filtered, an outlet for the filtered liquid and a belt of filter medium adapted to circulate within the filter tank and having a top side and a bottom side. The liquid to be filtered is introduced below the bottom side and is discharged between the top side and the bottom side. The filter material of the bottom side separates the unfiltered liquid from the filtered liquid and prevents floating particles in the liquid from reaching the outlet for the filtered liquid.
