Working principle
This product is mass-produced after modifications and optimizations to a German design. The final-stage piston utilizes a specialized process, the piston rings utilize Japanese Riken technology, and all castings are outsourced to specialized large-scale factories, earning widespread acclaim from users. This product utilizes four-cylinder, four-stage compression, oil pump lubrication, interstage safety valves, and a deep filtration system. The SLT-680 can provide safe compressed air for any industry requiring a high-pressure, pure air source, and also provides safe compressed air that meets human breathing requirements.
