Abstract

Die Erfindung bezieht sich auf eine Vakuumpumpe (1) mit einem im Ansaugbereich befindlichen Filter (18); um eine Abscheidung von Partikeln bis zu einer Korngröße von 1 µ ohne maßgebliche Beein­ trächtigung des Leitwertes zu erreichen, wird vorgeschlagen, daß der Filter ein Filtervlies mit Edelstahlfasern ist; zweckmäßig ist der Filter als versinters Metallfaservlies mit einem Gewicht von ca. 800 bis 1000 g/m² und einer Porösität von mehr als 90 Prozent ausgebildet. The invention relates to a vacuum pump (1) with a Suction area filter (18); for a separation of Particles up to a grain size of 1 µ without significant legs to reach the leading value, it is proposed that the filter is a filter fleece with stainless steel fibers; expedient is the filter as a sintered metal fiber fleece with a weight from approx. 800 to 1000 g / m² and a porosity of more than 90 Percent trained.
