Product Description

PP  Pleated Filter Cartridge For  Inkjet Inks Filtration
Inkjet inks are manufactured in a variety of formulations, including aqueous or solvent based fluids, pigments and dyes. Cleanliness of the ink is of utmost importance to avoid plugging of the print head or nozzle, ensuring printer performance and longevity.
Manufacturers of pigment based inks are looking for effective filtration. These filters must remove oversized pigments, gels and other contaminants, while still allowing the desirable sized pigments to pass through the filter and remain in solution. ANOW can offer special filters that may satisfy these demands of inkjet inks filtration, keeping reliable retention of particulates.
Please check chemical compatibility when selecting filters for solvent based ink applications.

Application Requirements
1. Filters must have low extractables, not to introduce foreigners.
2. Filters must remove oversized particles while allowing desirable sized pigments remaining.
3. Terminal filters must keep reliable retention of particulates for a long time.
4. Filters must provide consistent high flow rates and be robust to satisfy mass manufacturing processes.

Filtration Step






Final filtration


LEPF  filter cartridges are pleated, depth all-polypropylene cartridges offering high flow rates, high 
dirt-holding capacity and broad chemical compatibility. They are economical filters specially 
designed for extending the service life of terminal filters. Due to their features, they are ideal for inkjet
ink prefiltration on digital printing systems, and prefiltration of resins, solvents, pigments and dyes in the inkjet ink manufacturing process.

>> Cartridges produced in a controlled environment
>> Manufactured according to ISO9001 certified Quality Management System
