ABSTRACT:
Filtering apparatus having a housing defining an inlet and an outlet. Disposed within the housing is a plurality of filter elements constructed in tubular form and held together as a bundle of such elements. The entire bundle of elements may be removed from or inserted into the housing as a unit. Each of the tubular filter elements has a threaded fitting at each end thereof with the threads on each of the ends being adapted for mating engagement with each other. In this manner a plurality of the filter elements may be assembled in tandem form by threaded engagement of the mating ends thereof to provide the desired filter area and size for any particular application without the necessity of custom designing filter elements for each housing or application. The mating threads are formed on dissimilar non-galling metals. A header assembly is utilized to threadably receive one end of a filter element while a base assembly is adapted to receive and retain the second ends of the filter assemblies thereby holding them in a proper position internally of the filter housing.
