Abstract: A diamond patterned tubular pleated filter element is disclosed. Also disclosed is a filter cartridge that comprises a core element having an inner diameter, two ends and apertures formed therein, a diamond patterned tubular pleated filter element having an inner and an outer diameter positioned about the core element wherein the ratio of the outer diameter to the inner diameter of the diamond patterned tubular pleated filter element is about 1.5 to about 2.5, an open end cap, for transferring fluid into or out of the core element, positioned at one end of the core, and a closed end cap, for preventing fluid from exiting therefrom, positioned at the other end of the core, the closed end cap including structure for positioning the open end cap in filtration housing. Systems and methods for manufacturing the filter cartridge and the diamond patterned tubular pleated filter media itself are also disclosed.

Abstract: The present disclosure is directed to systems and methods of manufacturing filter cartridges are disclosed, the system including a tube of laminated and seamed filter media, a media unwind mechanism, a mandrel having a starting point operatively positioned proximate the media unwind mechanism, structure, operatively positioned proximate the mandrel, for feeding the tube of laminated and seamed filter media into the starting point of the mandrel, structure, operatively positioned in the mandrel, for pressurizing the tube of laminated and seamed filter media with a gas, structure, operatively positioned in the mandrel, for expanding the tube of laminated and seamed filter media into a substantially cylindrical shape as the tube of laminated and seamed filter media passes over the mandrel, a pleater mechanism, operatively positioned proximate the mandrel, a blade mechanism, operatively associated with the pleater mechanism, for alternately engaging the tube of laminated and seamed filter media with the blade mec
