ABSTRACT:
New, high surface area per unit volume, generally cylindrical filter cartridge for gaseous or liquid filter applications are described. These filter cartridges which comprise a nested arrangement of substantially disk shaped layers having a radial pleat pattern embossed therein, are capable of achieving higher surface areas per unit volume than can be achieved with conventionally pleated filter cartridges. Utilization of the filter media is extremely high as blocking of adjacent layers of filter media is avoided and fluids are evenly distributed over the total area of the filter media as a result of the series of channels created by the nesting of the disk shaped pleated layers.
