Two stage ejector without moving parts & lifting tube using compressed air


An industrial vacuum is an efficient method for handling objects. This technique has been developed to meet industrial automation needs, with applications in parts assembly, transfer, packaging, etc. Among the various techniques, the single stage ejector is very popular due to design durable with no moving parts. However, there are made for a high extraction rate either for  high vacuum level. To solve this problem, the multi-stage ejector has been developped. Nevertheless, this ejector is made of moving parts, degrading their reliability and robustness. Our technology consists of a 2 stage ejector  with no moving parts. Furthermore, this ejector allow to develop a lifting tube.
