Ejectors with air saving function EKPP


Energy saving function by integrated pressure control


  • Energy saving function through automatic pressure regulation
    - Full performance starting from 4 bar supply pressure
    - In between 4 - 8 bar supply pressure the ejector operates at 3,5 bar 
    - Air saving potential increases with difference between supply pressure and operation pressure
    - This saves up to 50 % energy with every workpiece - no matter if dense or porous
  • Significant reduction of sound level as exhaust pressure is independent of system pressure
  • Optimized open silencer reduces noise level up to 30 dBA and operates fully maintenance-free

Ejectors with air saving function EKP-LSE

Ejectors with air saving function EKP-LSE


Double energy efficient by electronic air saving function and integrated pressure control


  • Handling dense workpieces
  • Integrated electronic air-saving system
    - Reduces operating costs from 60 up to 90 %
    - When upper vacuum level set is reached (workpiece gripped), air saving function automatically shuts off the vacuum generator
    - When vacuum level has dropped to set lower threshold, vacuum generation is re-activated until upper vacuum level is reached again 
    - Integrated check valve keeps vacuum level set after vacuum generation is shut off
  • Integrated pressure control
    - Automatic pressure regulation to 4 bar reduces air consumption also during vacuum generation
    - Additional air saving potential increases with difference between feed and operation pressure
  • Integrated blow-off function for fast duty cycles
  • Blow-off flow manually adjustable
  • Safety function in the event of a power failure (Function NO) as integrated check valve keeps vacuum
  • Reduced sound level through integrated open silencer (~ 68 dBA without automatic air-saving system, ~ 0 dBA with active automatic air-saving system)
  • Dirt-proof construction, no filter required
  • Electric connection via 2 x M12 plug 5-pin (1 x input, 1 x output)
