Ejectors work on the Venturi principle; they are divided into single- Schmalz - The Company
stage ejectors and ejectors featuring eco-nozzle technology.
The compressed air is supplied through connection (A) to
ejectors. It flows through the venturi nozzle (B). The air is accele-
rated and compressed during this process. After passing through Knowledge
the nozzle, the accelerated air slows down once again and a Vacuum
vacuum is created. Air is drawn in this way through the vacuum
connection (D). The aspirated air and the compressed air escape
through the silencer (C).
Vacuum Suction Cups
With ejectors featuring eco-nozzle technology, the vacuum passes
through several venturi nozzles arranged in a row. The volumes of
the individual nozzles add up to form a total suction rate.
Advantages of ejectors Special Grippers
• Compact shape Principle of operation of a single-stage ejector
• Low weight
• Fast vacuum generation
• No flexible parts, resulting in low maintenance and low wear Vacuum Grip- ping Systems
• Choose an installation position
• No heat generation
Typical areas of application
• Industrial robot applications in all industries, such as feeder applications in the automotive industry Mounting Elements

We distinguish between three basic types of ejectors:
