Abstract
A filter unit (10) designed to filter process streams having different components and/or different fluid flow rates. The filter unit includes an elongated filter housing (12) having an inlet port (14) at one end and an outlet port (19) at the other end. A filter element flange (32) is fitted in the housing. The filter element flange is provided with a number of bores (34) that are provided with threading. Filter elements (28) with threaded coupling heads (36) are removably secured to the filter element array by fastening the coupling head in the threaded bores. This arrangement allows the replacement of the filter elements without having to completely disassemble the filter unit. In the event the number of filter elements is less than the number of openings that are in the element flange, plugs (84) are secured into the links in which the filter elements are not seated to prevent unfiltered fluid flow from the inlet port to the outlet port.
