US Patent 7300483 Modular filtration assembly

A modular filtration assembly for filtration of fluids, the capacity of the assembly depending upon the selected number of filtration modules included in the assembly. Each of the modules is made up of two identical housing members connected together in inverse, head-to-tail configuration and providing for inflow and outflow of fluid to and from a filter unit disposed in a recess formed by the two housing members. A housing inlet and housing outlet serve the function of assembly inlet and assembly outlet when the modules are assembled to one another to form the filtration assembly, providing for modularity and affording flexibility of capacity of the assembly.
