Ejector System - an overview | ScienceDirect Topics

Ejector systems can be very expensive to operate and there are good arguments for the use of a central vacuum system for the provision of vacuum to robot grippers (see Section 4.51).A vacuum pump uses far less energy and vacuum distribution can be with light-weight piping. • Tip – Investigate and cost the concept of using a central system for vacuum.
