3M Micro-Klean D series filter cartridge, 29.25 inch, 10 µm, model D-CCSC-3

When high flow rates, high filtration efficiency and consistent filtration characteristics are required from cartridge to cartridge, batch to batch, use the 3M™ Micro-Klean™ Series D filter cartridge. The filtration performance of the 3M Micro-Klean Series D filter cartridge is directly related to the special winding pattern of the yarn matrix and the winding process that applies a precisely fitting "media jacket" between yarn layers. The winding pattern creates much larger, diamond-shaped spaces for the contaminant, while the separately applied jacket seals these spaces and ensures the consistency and integrity of the filtration. The balanced filtration behaviour, as determined by these two factors, is difficult to achieve with normal wound filter cartridges, where only the roughened fibres of the yarn form the filtering medium. The winding pattern of the 3M Micro-Klean D series also offers less resistance to the media flow than normal wound cartridges. The 3M Micro-Klean D Series D filter cartridge has an open area up to 2 ½ times larger; this corresponds to a flow rate up to 500 % higher with an identical pressure drop. The filter concept works with effectively graduated density: more open filtration on the outside of the filter and highly effective fine filtration on the inner layer of the cartridge. This minimises clogging of the filtration surfaces by large particles and maximises the service life of the cartridge. One effect is lower replacement costs. The 3M Micro-Klean D series filter cartridges are available with nominal finenesses from 0.5 to 350 μm and various media, matrix and core materials for compatibility with different processes. The standard materials are cotton yarn and cotton cover for use in applications with water, alcohol and other polar liquids. The cotton materials and polypropylene yarns and jackets we use are FDA 21 CFR listed for use with drinking water, food and beverages. The filter cartridges can be ordered with cores made of galvanised steel, stainless steel or polypropylene. This choice of different core materials increases compatibility. A further selection of end caps and O-ring materials enables customisation to other filter housings.
