In principle, the subject matter only measures between one and three microns. That’s how fine the dirt particles are that can cause contamination in the hydraulic systems of injection moulding machines. The filters used on the machines are equipped with filter grades of between three and ten microns. This means that particle sizes of less than three microns can only be caught to a certain extent. But it is especially the concentration of ultra-fine particles that causes intense wear on the hydraulic components. Because conventional filters that function in the main stream only remove particles up to three microns, a so-called offline filter with an integrated motor pump unit has been developed by Stauff. Using this offline filter system (OLS), practical tests carried out with a renowned operator of injection moulding machines showed significant improvements in the purity class according to ISO 4406, namely from 15/13/10 (pressure filtration three microns) to 14/11/8. This result speaks in favour of Stauff’s strategy to back slow but highly effective filtration in the so-called bypass flow. With this technology, the fluid is drawn off the hydraulic system and passes through an ultrafine, purpose-developed cellulose medium that removes even the tiniest particles of less than one micron. The compact offline filter is easily installed in the hydraulic system of the machine and works independent of the plant cycle, even when the injection moulding machine is at a standstill.
