Abstract
A filter apparatus () for cleaning functional fluids, especially selected from phosphate esters, phosphate ester-based oils, mineral oils and phenols, includes a filter housing () into which a filter bed () has been introduced. The filter bed has a mixture of anionic and cationic ion exchange resins. At least one filter element (), designed as a flow guide device, enables the diversion of the fluid from a radial to an axial flow direction () or vice versa.
