ZU-H, QU-H series oil filter are of high pressure type and used in the pressure line of hydraulic system, for filtering the mechanical impurities, rubber impurities, asphalt impurities, carbon residue impurities and other contaminant. These can protect filter element accumulated fully from hydraulic system accident.

This series oil filter has the merit of good filtration effects and high filtration accuracy but clean difficult.

This series filter is equipped with differential pressure indicator. It will give signals when the pressure drop across the element reaches 0.35mpa, showing the oil filter element should be cleaned or changed in order to protect the oil filter work safe.

Filter element material is consisting of glass fiber with high filtration accuracy, huge oil fluxion, low initial pressure loss, large dirt-holding capacity and so on. The filtration accuracy is assessed by absolute filtration accuracy. Filter ratio β 3, 5, 10, 20>200, filter efficiency≥ 99.5%.

Assessment method: ISO16889-99 & GB/t18853-2002
