Filtering cartridges consist of cellulose filtering walls impregnated with special, strong resins.
Thanks to the folding, a wider filtering surface may be obtained compared to the small space which is available.
On a diameter of 300 millimetres, a filtering surface of no less than 4 square metres may be obtained.
