Micron Filters

Cartridge filtration units generally operate most effectively and economically on applications having contamination levels of less than 50 – 80 ppm. For heavier contamination applications, cartridges are normally used as final polishing filters. In the following the basic systems of cartridge filters are listed

•     the most common type of depth filters
•     materials: natural or synthetic yards, which are wounded around a central tube or former
•     numerous applications in the industry

•     One-piece cordless construction, consisting of resin bonded fibers of solid particles
•     Their filtration range is between 5 to 125 micron, good chemical compatibility/flow rate
•     Frequent application: viscous fluids, process duties

•     today's most common cartridge filter system
•     materials: cellulose basis, resin impregnation; polyester, micro fiber glass, polypropylene
•     advantages: increased surface area (up to 60 %) compared to traditional cartridge filters

•     material: stainless steel fibers, connected to a mat
•     used in the polymer industry

•     for applications under 0.5 micron, for example used for the removal of aerosols.
•     Further applications can be, for example microbiology (filtration range down to 0.01 micron), where sterility is very important
•     materials: hydrophilic polyamide/polypropylene

•     Pre RO water
•     Chemicals
•     Beverages
•     Solvents
•    Compressed air
•     Cosmetics
•     Alcohol
