White Paper highlights best practice and innovation in hydraulic filtration media

Contamination remains a primary cause of hydraulic system malfunctions according to a new white paper released in April 2017 by Bosch Rexroth, which examines the importance of filtration.

No other industrial and manufacturing drive technology provides the power density, life cycle performance and resistance to adverse environmental conditions offered by hydraulics. However, this only applies as long as the fluid is contaminant-free.

The white paper titled, ‘New filter materials for hydraulic systems: Longer service life and reduced operating costs ’, details the vital role of filtration. In particular it discusses fifth-generation technology filter materials which now offer breakthroughs in filtration performance, reducing operating costs and increasing the life cycle of hydraulic systems.

Chis Gray, Project Manager - Filtration at Bosch Rexroth, commented: “Hydraulic fluid is often referred to as the ‘lifeblood’ of hydraulic systems, and with good reason - research findings show that 80% of malfunctions are caused by contamination. Tiny particles, not visible to the naked eye, can be damaging to a hydraulic system and can even lead to the write-off of equipment.

“Particles can enter the system through a number of ways - while in operation or even during the assembly of new hydraulic systems. In fact, new operating fluids can harbour inadmissibly high levels of dangerous particles, so users should never assume they are clean, and therefore safe. This is why filtration is absolutely key.”

The report also discusses the impact of contamination which can lead to the physical damage to system components with the potential for serious system malfunction. It then gives some best practice guidance on technical criteria for filter selection.

Mr Gray continues: “New materials made of micro-glass fibres have been designed specifically to retain very small particles. Measured in ß-values, new filter media comfortably exceed 200, achieving optimum retention rates. As well as high filtration efficiency, the new filter technology also increases the dirt-holding capacity, absorbing up to 50% more particles – reducing the likelihood of system downtime.

“With the help of advanced filter media, manufacturers can reduce operating costs, while keeping the same operating conditions, and ultimately protect hydraulic systems to maximise service life.”
