Multi – pass test (ISO 4572) Imitation filters filtration efficiency is 60% to 90% lower than Hitachi genuine filters. Test results show there is a high possibility that contamination will enter the hydraulic circuit. Hitachi’s research shows more than 60% of hydraulic component failure came from contamination in hydraulic oil. It is safe to say that there is a high risk of hydraulic component failure, when using imitation filters.
