InkJet Filtration Products

Meltgradient Series Depth Filters are made of melt-blown polypropylene with gradient pores and an inner layer of interwoven high-density nano-fibers. The cartridge is capable of efficiently capturing particles of different sizes with a great flow rate and lifetime. The polypropylene raw material meets FDA requirements with extensive chemical compatibility, suitable for filtering inks, coatings, solvents, water, etc.

PoliFlow® Filter Cartridges are composed entirely of pleated polypropylene microfiber whichprovides great filtration performance with a low cost. Characteristics include high flow rates, high contaminant holding capacity and filtration efficiency making it the ideal solution for the pre-filtration of liquids.

MultiPoly® Filter Cartridges are composed of multi-layered pleated polypropylene. These filters have a depth filter design that includes graded pore size and a high contaminant holding capacity which eliminates contaminants (including gels and agglomerates) in highly viscous liquids and avoids filter surface plugging. The graded pore size distribution from coarse (upstream) to fine (downstream) removes particles gradually and extends the filter’s service life making it especially suited for eliminating contaminants in ink.

PolyRolled® Depth Filters are made of continuously rolled polypropylene microfiber (for a total of 56 layers). The outer layers are constructed of graded pore sizes, while the inner layers are uniform. This provides a large filter depth for particulate capture and high efficiency. Highly recommended for pigment-based inks, ceramic inks, and disperse ink jet inks filtration.

Ultrapore® Filter Cartridges are used as a final filtration for pigment-based inks, dye-based inks, and ceramic ink jet inks. The polypropylene nano fiber outer layers provide high flow rates, and the multi-layers of super fine glass micro fiber contribute to high efficiency.

GlassFlow® Filter Cartridges are composed of super-fine glass fiber media with a pre-layer constructed of polypropylene for pigment-based ink and dye-based dispersed inks for use during pre-filtration and final filtration. Glass fiber media has an inherently absorptive characteristic that enhances filter retention capability.

ProtectPP® 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.

Absoguard filter cartridges are all-polypropylene pleated depth filters that combined uncalendared meltblown and nanofiber media to provide high efficiency with excellent particle retention. Absoguard filters are an excellent choice for a wide range of digital printing inkjet inks filtration, especially for pre-filtration of dye-based inks.

Cobetter SuperPVDF® series polyvinylidene fluoride filters are made of PVDF membranes which are resistant to organic and inorganic solvents. The SuperPVDF is ideal for use in normal dye-based ink, eco-solvent dyes, and color paste fi ltration. The LHPV version adopts a hydrophilic modifi ed PVDF filter membrane and can be used directly without wetting.

TeflonFlow Filter Cartridges are available as hydrophobic PTFE or hydrophilic PTFE filters with polypropylene supports. TeflonFlow hydrophobic filters are ideal for use with wide range of chemicals with excellent corrosion resistance. The TeflonFlow hydrophilic version has no pre-wetting requirement, ideal when operating with aqueous-based liquids. These filters are recommended for final filtration of marking and coding inks.

ChemfineN66® Filter Cartridges are constructed of Nylon 66 membrane and are widely used in dye-based ink filtration applications. Nylon 66 membrane is naturally hydrophilic with broad chemical compatibilities. ChemfineN66® is available in single-layer as well as a double-layer membrane configurations.

Duredunty® Filter Cartridges use a unique double-layer PES membrane and are designed as a final filter for dye-based inkjet inks filtration. The double-layer membrane provides excellent filtration efficiency, eliminating the difficulties encountered by dried ink particles and gels.

AdvanLife® Filter Cartridges feature a unique single-layer asymmetric hydrophilic polyethersulfone membrane. They are desgined for filtration of aqueous liquids, including dye-based ink jet inks. The filter's membrane is characterized by high particle holding capacity, high flow rate, high efficiency and longer lifetime.
For dye-based ink, AdvanLife® Filter Cartridges can be used as the final filter for effective particle removal, however, for some special inks that need high-speed printing, such as active dye inks and acid dye inks, AdvanLife® Filter Cartridges are recommended as a pre-filter.

SteriPS® Filter Cartridges are specially designed to provide superior flow rates, high retention efficiency for dye-based ink jet inks final filtration. The cartridge featrues a single-layer symmetric hydrophilic polyethersulfone membrane.

Cobetter® NPT Series Capsule Filters are available in a variety of housing sizes and filtration media to meet the needs of a diverse range of printer inks, flow, and filtration requirements. These filters are ideal for matching with a variety of printer models, digital ceramic printers, wide format printers, and marking and coding filters.

Cobetter® Hose Barb Capsule Filters are available in a variety of housing sizes and filtration media to meet the needs of a diverse range of printer inks, flow, and filtration requirements. These filters are ideal for formulation or small ink batch production processes.

Cobetter® NPT Series Capsule Filters are available in a variety of housing sizes and filtration media to meet the needs of a diverse range of printer inks, flow, and filtration requirements. These filters are ideal for matching with a variety of printer models, digital ceramic printers, wide format printers, and marking and coding filters.

Cobetter® Hose Barb Capsule Filters are available in a variety of housing sizes and filtration media to meet the needs of a diverse range of printer inks, flow, and filtration requirements. These filters are ideal for formulation or small ink batch production processes.

Cobetter® DIP Series Capsule Filters are available in a variety of fittings and filtration media to meet the needs of a diverse range of printer inks, flow, and filtration requirements. The DIP capsules have a round-corner design which can withstand20 bar (290 psi) of pressure. In addition, the capsules can withstand more than 10,000 pulses. Thissatisfies the demanding requirements for high pressure ink systems such as continuous inkjet printers.

Cobetter® Small Volume Capsule Filters have been widely used in wide-format printers for solvent / water-based inks. These capsules feature high filtration areas for long service life and low initial pressure drop, ideal for situation where space is at a premium.

Cobetter® 58 Disc Point-of-Use Filters with their high flow rate features are specially designed for digital ink-jet printers which require high-speed printing, printheads including digital ceramic printers, wide format printers, and UV flatbed printers.

Cobetter® High Flow Last Chance Filters provide small volume, easy connection, and simple design. They have been used in marking & coding printers, wide format printers, and textile printers. These filters can be used as printhead filters or inline connection filters to avoid system tube ink aggregate and to protect the printhead.

Cobetter® 4075FX Disc Point-of-Use Filters with their high flow rate features and 40 cm width are specially designed for digital ink-jet printers which require high-speed printing, printheads including digital ceramic printers, wide format printers, and UV flatbed printers. This fi lter, usually installed before the printhead, is able to remove impurities from ink and prevent clogging.

Cobetter® Point-of-Use Disc Filters are ideal solutions for final filtration to protect print heads as well as for testing ink formulations and conducting printing trials. These filters are available in four kinds of media: PPEP - non-fiber releasing polypropylene, PTFE hydrophobic membrane, Glass fiber media, and stainless steel mesh. Additionally, these disc capsules are available in a wide range of configurations including hose barb, Luer Lock, NPT, and quick-coupling.

Cobetter® Dampers have been widely used in digital inkjet printers. These units can reduce printer system back flush pressure when printers operate in positive pressure. They can also prevent recycled ink from damaging precision printer components. The damper itself has enough volume that it can be used as a foam breaker for reserve inks and effectively protect electron magnetic valves.
