Schmalz Eco Nozzle Technology

The Core of Efficient Vacuum Generation. For More Performance and Less Consumption.


Customized vacuum generation for your application
  • Various possibilities for integration
  • Centralized and decentralized vacuum systems can be realized
  • Two characteristics available depending on the workpiece
15 % higher suction capacity
  • Reliable handling of even porous and flexible workpieces thanks to high flow rates
  • Large operating range of -250 to -850 mbar
  • Accelerated process thanks to faster evacuation times
15 % less compressed air consumption
  • Compressed air consumption reduced by 15 % during active vacuum generation
Functional Principle and Characteristics

The eco nozzle technology is based on a multi-stage venturi principle. Schmalz has refined this technology to make vacuum generation with compressed air more efficient, thus offering an ideal combination of suction capacity and energy efficiency. Core of the entire product line is the ejector module ecoPump. The ecoPump is available in two characteristics, depending on the application area. They provide an almost identical suction capacity, but differ in terms of the maximum achievable vacuum.

High Vacuum (HV) for airtight applications

  • Use in applications where a high vacuum can be reached
  • Ideal for airtight workpieces

High Flow (HF) for porous applications

  • Use in applications where a high vacuum cannot be reached
  • Reaches the same suction rate as the HV version with a lower compressed air consumption
  • Saves energy when handling porous workpieces



Product Range and Integration Possibilities
