New generation of hydraulic filter elements
4th Quarter 2017, Hydraulic systems & components

Bosch Rexroth has introduced a new range of hydraulic filter elements incorporating new materials that enhance filtration performance while reducing operating costs through increased service life. The Pure Power range of elements has a new micro-glass material that, due to the very small diameter of the fibres, increases interstitial spaces to trap and retain 50% more contaminant particles. The β-values of the new Pure Power filter material have exceeded 1000 in real world tests, so hydraulic fluids are cleaned to an optimum condition. This also prevents further contamination and damage to the system by removing a very high proportion of the contaminants in the first pass through the filter.

All elements in the range have an additional antistatic conductive woven filter medium to reduce the risk of electrostatic charge and discharge in the filter. End users of hydraulic systems increasingly use zinc- and ash-free oils which typically have reduced conductivity. If this is less than 300 pS/m, the danger of electrostatic discharge increases. This reduces the retention rate and increases the danger of particles passing through the filter and causing damage in the system. The antistatic conductive woven filter medium helps negate the risk of these issues.

Filtration efficiency is even more effective when used with Rexroth filter housings with patented Cycloclean cyclone technology, where a doubling in dirt-holding capacity has been measured according to the ISO 16889 multi-pass test, while retention capability increases tenfold using the same test. This is a direct result of the cyclone design maximising filter capacity by effectively pre-filtering the fluid.
