Oilless air compressor

The utility model provides an oilless air compressor, which relates to the technical field of heat dissipation of oilless air compressors and comprises an oilless air compressor body and a base for mounting the oilless air compressor body, and two dust covers for covering the oilless air compressor body are symmetrically arranged on the base. A sliding rail is fixedly connected to the position, located on the oilless air compressor body, of the base, an L-shaped air pipe used for air cooling of the surface of the oilless air compressor body is connected to the sliding rail in a sliding mode, an air blower is fixedly connected to one side of the base, and when the L-shaped air pipe horizontally slides in a reciprocating mode, a rack is driven to correspondingly horizontally slide in a reciprocating mode. Therefore, the gear ring in meshed connection with the rack rotates forwards or reversely, the brush rotates, and dust on the surface of the filter cotton is cleaned. 本实用新型提供一种无油空压机，涉及无油空压机散热技术领域，包括无油空压机机体，和用于
