Pigment ink generally consists of carrier fluid, colorant, and pigments. Filson ink filter removes oversized contaminants such as insoluble pigments, gels, agglomerate, etc. and it can keep the pigments not to be removed in the solution.

Solvent-Based Ink

In general, microglass fiber filters and PES cartridge filters are the most commonly used in filter solvent-based ink. Filson ink filter has a micron rating range from 0.1 microns to 150 microns, effectively capturing contaminants in ink.

Dye-Based Ink

To achieve a better filtration effect, dye-based ink should be filtered twice. Filson PP pleated filter cartridge is a primary filter and PES pleated filter cartridge is a secondary filter, which can prevent ink from clogging the device when in use.

UV Curable Ink

Due to the UV ink has high viscosity, Filson glass fiber filter cartridge is specially ideal for filtering it. Our filters has excellent performance to preserve appropriate gel content in ink, which can greatly improving the quality of ink.

Pigmented Solvent-Based Ink

The best filter micron grade of pigmented solvent-based ink is 0.5 micron. Filson ink filter has precise and uniform pore size that enables accurate filtration of ink, it can also maintains the optimal concentration and component of ink.

Inkjet Ink

The main purpose is to remove resin, gel, particles and other big size pollutants in ink, Filson stainless steel filter housing and PP filter bag can effectively purify inkjet ink and extend the service life of printing equipment
