Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a dry vacuum pump air filter. Background Art

[0002] A dry vacuum pump is a mechanical vacuum pump that can pump air from atmospheric pressure and discharge it directly into the atmosphere. The pump chamber contains no oil or other working media, and its ultimate pressure is comparable to or similar to that of an oil-sealed vacuum pump. To ensure the quality of the air being filtered, the incoming air must be filtered through an air filter to ensure cleanliness at the outlet and reduce dust accumulation within the dry vacuum pump during operation.

[0003] The air filter needs to have its internal filter element replaced after being used for a period of time. When disassembling and replacing the filter element of the existing air filter, it is necessary to first remove the replaced filter element and then install the new filter element. This process takes a long time and affects the use of the dry vacuum pump. For this reason, we propose a dry vacuum pump air filter. Utility Model Content
