Hydraulic system failures and reduced component life are frequently caused by excessive hydraulic oil contamination.
To protect hydraulic systems from particulate contamination, ISO 4406 defines maximum contamination limits based on particle counts per unit volume (mL) at specified particle sizes.
To reach the required cleanliness level, an independent filtration system — consisting of an internal gear pump and filter — circulates oil from the reservoir through the filter, steadily reducing oil contamination levels.
The dielectric strength of insulating oil is affected by contaminant particles, which may include metallic debris, sludge, fibers, and moisture. When the filtration process uses a pumping and filter system with technology suited to each contaminant phase, the result is cost savings through oil reuse, plus environmental benefits.
