Abstract

A vacuum pump includes a casing having a first inlet orifice and a second outlet orifice to allow a flow of air, and in the interior of which a filtering element is mounted in a removable way. At least one orifice of the casing selected from among the first inlet orifice and the second outlet orifice is located on an exhaust lid. The exhaust lid is removable from the casing but integral with the filtering element. The connection between the casing and the exhaust lid is not tight. A cartridge for the vacuum pump includes an exhaust lid integrated in the closure nozzle of the filtering element. The connection between the casing and the exhaust lid is not tight.
