About Vacuum ejectors

Vacuum ejectors generate negative pressure right at the gripping point by driving compressed air through a nozzle on the Venturi principle. No separate vacuum pump is needed, the existing air network does the work at an operating pressure of 4.5 to 6 bar. The group runs from the small basic ejector to the compact ejector with vacuum switch and air saving control.

What matters when choosing

• Nozzle size is the first criterion. Together with the maximum suction rate it decides how quickly the workpiece is held.
• Air consumption during suction drives the running cost. It weighs more heavily on long holding times than on short cycles.
• Connection: push in connector, plug connection or threaded connection. Plug versions are quicker to fit, threaded ports suit fixed pipework.
• Operating pressure: versions are rated for a maximum of 4.5 to 6 bar and some call for at least 5 bar. Line pressure has to match the design point of the nozzle.
• Size: length ranges from 35 to 228 mm. For mounting directly on the gripper, width, height and a fitted silencer count alongside length and weight.

Typical applications

• Handling sheet metal and panels with vacuum cups
• Labelling and packaging machines with short cycle times
• Pick and place and part feeding in electronics production
• Workholding on vacuum tables at machining centres
• Local vacuum generation at the machine instead of a central pump

Depending on version the housings are made of plastic, of impact resistant plastic or of anodised aluminium. Production takes place in Germany and China.
