Bosch Rexroth has introduced a new range of hydraulic filter elements.
The new range of elements, known as PURE POWER, has been designed using new micro-glass material to retain 50% more contaminant particles than the range it is replacing. This is due to the very small diameter of the micro-glass fibres allowing for more interstitial spaces in the same given area to trap and retain contamination.
 
The micro-glass main filter layer assists in achieving optimum retention rates. In order to meet the requirements of ISO 16889:2008 (the international standard for evaluating filter performance), any filter element must have a ß-value exceeding 200, depending on the filter particle size rating. The ß-values of the new Pure Power filter material have exceeded 1000 in real world tests.  This maximizes system availability as hydraulic fluids are optimally cleaned.  It also prevents damage to the system and further contamination by removing a very high proportion of the contaminants in the first pass through the filter.
