Multi-chamber ejectors

Multi-chamber ejectors, also called multi-stage ejectors, use multiple successive nozzle chambers. In comparison to single-stage ejectors, such as inline ejectors for example, they use less compressed air to achieve the same suction power. The benefits are short evacuation times at low vacuum levels.

FIPA multi-chamber ejectors are used for applications that handle porous workpieces, such as insulating materials, cardboard and fibreboard. They achieve moderate cycle times when handling suction-tight materials.


The lightweight construction of 65.310 – 65.330 series multi-chamber ejectors enables highly dynamic handling systems. The vacuum generation can “hitch a ride” on the gripper.


FIPA multi-chamber ejectors with automatic air-saving function can noticeably reduce compressed air consumption for pick-and-place applications with suction-tight products, such as fibreboard and sheet metal for example. The air-saving function automatically switches the vacuum generation off when, for example, downstream handling processes are delayed. Multi-chamber ejectors with automatic air-saving function are designated by the Index LSE.

FIPA multi-chamber ejectors with automatic air-saving function also use less compressed air when filling the vacuum tank.


We recommend contacting our Technical Sales Department to discuss whether the automatic air-saving function is technically and economically feasible for your application.

Application example: Multi-chamber ejector 65.340-LSE with air saving function
  • High vacuum level at low feed pressures, and thus particularly efficient use of compressed air as well as suitability for fluctuating air pressure levels
  • Handling of porous products, or for high leakages
  • High suction power for short evacuation times in the lower vacuum range
  • Noise-optimised operation due to open silencer
  • Industry examples: packaging and printing


Air saving function (Index LSE)

  • Saving compressed air during handling of dense workpieces
  • Examples of use:
    Automatic switching off of vacuum generation during Pick & Place applications of dense workpieces if e.g. downstream processes are delayed. Saving compressed air when using the multi-chamber ejectors for feeding vacuum tanks.

+Ordering notes

  • Seals optionally available in NBR as standard
  • Optionally available in EPDM or Viton upon request
  • Included in scope of delivery: Two mounting brackets and G1/4"-male - Ø 10 mm quick fitting for compressed air connection

+Notes

Construction / operation (Index -LSE):

  • Combination of pneumatic control valve with spring return and normally closed (NC) pneumatic vacuum switch
  • Setting target vacuum values by means of setting screw
  • Compressed air is conveyed through the valve to the compressed-air inlet of the injector; there is a partial airflow at input 1 of the vacuum switch
  • When set target vacuum is reached, vacuum switch opens, compressed air from input 1 is conducted to the control valve via output 2 and closes it - the vacuum generation is stopped
  • If the vacuum level has reached the hysteresis value (see table), the vacuum switch closes again and the spring opens the control valve - vacuum generation is activated again
  • Please note: The air saving function does not work with porous products, or in the case of high leakage
