Ultragrade Performance 20, 4x4l (H11024011) von Edwards

Edwards Ultragrade 20, 4x4l (H11024011) ist ein speziell entwickeltes Mineralöl für Vakuumpumpen, das durch seinen einzigartigen hydrotreatment Prozess ein nahezu reines Basisöl bietet. Dieses Verfahren entfernt Stickstoff, Schwefel, Sauerstoff und aromatische Kohlenwasserstoffe, und in Kombination mit Additiven resultiert dies in verbesserter Vakuumleistung, thermischer und oxidativer Stabilität sowie Rostinhibition. Dank der enthaltenen Antioxidantien kann die Pumpe hohen Betriebstemperaturen widerstehen, ohne dass das Öl abbaut, was zu längeren Ölwechselintervallen führt. Ultragrade 20 ist vielseitig ein setzbar und gewährleistet eine optimale Leistung Ihrer Edwards Vakuumpumpe.
