AIRTEC Column Ejectors
The Concept
The column ejector get it’s name from it’s cylindrical geometry. The pressure supply is introduced radially on the ejector body and routed internally into the center of the ejector. The air flow is directed downwards through an orifice to a baffle plate and is accelerated radially in all directions until the desired sub- or supersonic speed is obtained at the point of ejection 1. At this point the air expands and vacuum is created (Venturi principle). At point 2, the accelerated air flow is mixed with the drawn air. At point 3, the air speed is reduced and flows direct ly upward through a silencer to atmosphere. Several vacuum ports are positioned around the outer diameter into point 2, to connect several vacuum cups on one ejector.
The vacuum is maintained on all ports, even in cases where one or several cups draws to atmospheric pressure. Additional valves or pressure control are not required. This increases operating safety while reducing start-up costs.
The new body design makes the ejector highly efficient. In vacuum ranges above 40 %, the column ejector achieves a performance, at equal air consumption, that can only be matched by multistage vacuum ejectors. The compact form, along with its lightweight design, provides for new application possibilities in the area of vacuum technology.
