ABSTRACT:
The present invention comprises a fluid filter element which has a hollow perforate cylindrical supporting core. A relatively fine filter media of substantial cross section is spirally wound about the supporting core with adjacent layers spaced from each other and with the fine filter media accommodating fluid flow for filtering in both a radial and circumferential direction through the cross section and with free access through the cross section to the supporting core. In substantially the same manner, a relatively coarse filter media of substantial cross section is disposed in the space between the layers of fine filter media and with the coarse filter media exiting at the supporting core, the coarse filter media accommodating fluid flow for filtering in both a radial and circumferential direction through the cross section and with free access through the cross section to the supporting core. A central barrier is disposed adjacent the supporting core and at least one of the layers of filter media in approximately the center of the filter element to assist in the filtration process.
