ABSTRACT:
Compound filters using two different filter element types are disclosed. When a carbon element is used it is of the concentric type having a central cavity. Filter elements for filtering very fine particles are used in addition. Various types of such elements, including hollow fiber elements, are disposed in a lower portion and/or upper portion. Flow control arrangements, improved filter element removal arrangements, improved filter sealing arrangements, accommodations for filter elements having different lengths and tolerances and filter arrangements for preventing liquid flow when no filter element is present are described.
