The integral closed endcap/spring assembly eliminates the requirement for the customer to individually place loose springs and cups on the top of each and every filter. This makes filter changeout quicker and easier in multiple around cartridge housings. The SI configuration also will enhance product quality since the cartridge is permanently sealed at one end, thereby minimizing the risk of fluid bypass with a double open ended filter.
Profile II depth style filters are all polypropylene. The 21⁄2 inch diameter elements have an absolute rated downstream section, and a continuously profiled pore size upstream section, which significantly increases service life. The material of construction — chemically resistant polypropylene — permits application in a very wide range of corrosive and non-corrosive fluids. The fibers in Profile II filters may be considered continuous. No binder resin is used, as the fibers are bound by intertwining during the manufacturing process. As a result, Profile II filters show no media migration.
Pall Ultipleat Profile filters are 21⁄2 inch diameter pleated polypropylene cartridges. Just like Profile II filters, the absolute rated filter medium within Ultipleat Profile elements is constructed using Pall's proprietary method of continuously varying fiber diameter to create a tapered pore filter medium
As a result of this unique medium construction and a proprietary crescent-shaped pleat structure, the pressure drop of Ultipleat Profile filters is as low as half that of higher area pleated filters, and as low as one-fifteenth that of conventional depth filters. Consequently, Ultipleat Profile filters provide exceptional service life. The Ultipleat Profile medium is thicker than that found in many conventional pleated filters and is optimized for gel removal and sharp, distinct particle removal. This makes the elements ideal for viscous fluids and dispersions in addition to those many applications where long service life is desired.
Ultipleat Profile and Profile II filters have numerous applications in a broad range of industries that include chemical, petrochemical, photochemical, pharmaceutical, biological, electronic, magnetic tape, electroplating, food and beverage, cosmetic, veterinary, medical and fermentation industries. They are used as both prefilters and final filters.

|In Microns (μm) at 90% Efficiency||In Microns (μm) at 99.98% Efficiency||Aqueous Service PSI/GPM Per 10 Element||Gaseous Service CFM of Air Per PSI Per 10" Cartridge(3)|
(1) Precision evaluation of the 99.98% removal efficiency for these coarse grades is not possible with the modified OSU test procedure utilized.
(2) Pressure drop in PSI per GPM for a single 10” cartridge. For multiple number of elements, divide by the number of cartridges. For fluids other than water, multiply the value calculated by the fluid's viscosity measured in centipoise.
(3) For longer modules, increase the flow rates listed in proportion. The flow rates listed do not take into account pressure losses due to flow in the internal diameter of the element, which becomes significant above about 40 to 60 cfm.
(4) Precision evaluation of the 99.98% removal efficiency for these coarse grades is not possible with the modified OSU test procedure utilized.
