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.

Abstract: The present invention relates to a vacuum pump (1) comprising a casing (2) in which are disposed a first inlet orifice (21) and a second outlet orifice (22) to allow the flowing of a flow of air (F), and in the interior of which a filtering element (3) is mounted in a removable way, wherein at least one orifice of the said casing (2) selected from among the said first inlet orifice (21) and the said second outlet orifice (22) is disposed on an exhaust lid (4) which is at the same time removable from the said casing (2) but integral with the said filtering element (3) and wherein the connection between the casing (2) and the exhaust lid (4) is not tight. The present invention also relates to a cartridge (30) for the corresponding vacuum pump (1) wherein an exhaust lid (4) is integrated in the said closure nozzle (32) of the filtering element (3), the connection between the casing (2) and the exhaust lid (4) not being tight.
