Filtration for Ink Production

ink-jet-capsule-NPT-cbt-02.jpg

The optimization of ink filtration process has always been a major problem. Agglomerates, by-products and large size pigment particles that was needed to be solved. According to the impurities in the ink, different filter materials and processes of filtration products are provided that these targeted solutions will be more accurate. The filter membrane materials independently developed by Cobetter make all this easier to achieve. In addition, there are capsule products for selection in the actual using for a more easier operation.


  • AdvanLife Filter Cartridges Cobetter AdvanLife Filter Cartridges feature a unique single layer asymmetric hydrophilic polyethersulpone membrane. They are designed for filtration of aqueous liquids, including dye-based ink jet inks. It’s membrane is characterized by high dirt holding capacity, high flow rate, high effiiciency and longer life time.
  • GlassFlow Filter Cartridges Cobetter GlassFlow​ Filter Cartridges are made of super fine glass fiber media with a pre-layer constructed of polypropylene for pigment-based ink and paste and dye-based dispersed inks and paste for use during pre-filtration and final filtration. Glass Fiber Media has an inherently absorptive characteristic that enhances filter retention capability.
  • Ultrapore Filter Cartridges Cobetter Ultrapore® Filter Cartridges are used as a final filtration for pigment-based inks, dye-based inks, and ceramic ink jet inks. PP Nano Fibers outer layers provide high flow rates and multi-layer of super fine glass micro fiber contribute to high efficiency.
  • Meltgradient High-efficiency Depth Filter Meltgradient series is the PP melt-blown cartridgewith the absolute filtration rate. It adopts the reasonable gradient pores configuration, cooperating with the structure of "deep". The cartridge is capable of efficiently capturing particles of different sizes, and its flow rate and life are not inferior to the pleated cartridge. Polypropylene raw material that meets FDA requirements, with extensive chemical compatibility, suitable for filtering inks, coatings, solvents, deionized water, etc.
  • EnCap Filter Cartridges Cobetter EnCap® Easy Change Filter Cartridge, with a polypropylene outer shell, uses encapsulated technology. They are specially designed to provide increased efficiency and safety in the ink manufacturing process. No adhesives or glue are used in the manufacturing process, and all bonding is done by thermal welding.
  • SteriPS Filter Cartridges Cobetter SteriPS Filter Cartridges are specially designed to provide superior flow rates, high retention efficiency for dye-based ink jet inks final filtration. The cartridge features a single-layer symmetric hydrophilic polyethersulfone membrane.
  • StarCap UCF-T Capsule Filter Cobetter StarCap UCF-T Capsule Filter is self-contained and ready to use filter for removal contaminants and particles for inkjet ink formulation applications. This kind of design makes change-outs quick and convenient while reducing operator contact with inks. No adhesives or glue are used in the manufacturing process, and all bondings are done by thermal welding.
  • Absoguard Filter Cartridges Cobetter Absoguard Filter Cartridge is an pleated depths filter. It combines and nano fiber media, provides absolute efficiency with excellent particles retention. Cobetter Absoguard Filter is an excellent choice for a wide range of digital printing ink jet inks filtration, especially for pre-filtration of dye-based inks.
  • PolyRolled Filter Cartridges Cobetter PolyRolled Depth Filters are made of continuously rolled microfiber (for a total of 56 layers).The outer layers are constructed of graded pore size while the inner layers are stable pore size. This provides a large filter area and high efficiency. Highly recommended for pigment-based inks, ceramic inks, and disperse ink jet inks filtration.
  • ProtectPP Filter Cartridges Cobetter ProtecPP Filter Cartridges are made of thermally bonded polypropylene microfibers. This unique technology forms a rigid fiber structure providing final protection to ink jet inks prior to filling by eliminating the risk of releasing fibers.
  • Duredunty Filter Cartridges Cobetter Duredunty Filter Cartridges are made of a unique double-layer PES membrane and are designed as final filter for dye-based ink jet inks filtration. The double-layer membrane provides excellent filtration efficiency and can eliminate most of the difficulties encountered by inadequate removal efficiency.
  • SuperPVDF Filter Cartridges Cobetter SuperPVDF series is polyvinylidene fluoride filter, which is made of vinylidene fluoride filter membrane resistant to organic and inorganic solvents. It can great apply to normal dye-based ink, eco-solvent dyes and color paste filtration. LHPV adopts hydrophilic modified PVDF filter membrane, it can be used directly without wetting.
  • TeflonFlow Filter Cartridges Cobetter TeflonFlow Filter Cartridges are manufactured with an inherently hydrophobic PTFE membrane that maintains broad chemical compatibility for excellent corrosion resistance. Narrow pore size distribution ensures the highest retention and flow. It is also available as a hydrophilic PTFE membrane for no pre-wetting requirement when in operation. Recommended for marking & coding inks final filtration.
  • MultiPoly Filter Cartridges Cobetter MultiPoly Filter Cartridges is an all-polypropylene pleated depth filter cartridges The design adopts depth filter technology for a graded pore size, higher dirt holding capacity, avoids filter surface jams, and eliminates ink contaminants (gels and agglomerates). The graded pore size distribution from coarse (upstream) to fine (downstream) removes particles gradually and extends the filter’s service life.
  • ChemfineN66 Filter Cartridges Cobetter ChemfineN66 Filter Cartridges are constructed of Nylon 66 membrane and widely used in dye-based ink filtration applications. Nylon66 membrane is naturally hydrophilic with broad chemical compatibilities. DN66 series , which is a double-layer membrane design , is also available.
