Vacuum Ejector General Precautions  
         
  1   In order to achieve the highest vacuum degree, make sure the pressure level  
      over [ 3.5 ~ 5 kgf/cm2 ] can be supplied by air compressor  
                       
  2   Compressed air consumption of Vacuum Ejector [ 9.7 ~ 385Nl/min ]  
      When use more Vacuum Ejector, please check compressor energy  [ 1HP ] [ 80Nl/min ]  
                       
  3   The recommended system is one vacuum pad per Vacuum Ejector, in order to avoid the pressure  
      being reduced during the operations of other air compressors.  
                       
  4   Never use lubricant in the pipes of Vacuum Ejector.  
         
  5   Please keep the water and impurities clean in the circuit to ensure the vacuum degree.  
         
  6   Use filter-Regulator, please check supply air flow is sufficient.  
         
  7   In Vacuum Circuit, Vacuum Ejector has to be placed near the pad.  
                       
 
  Principle  /  หลักการทำงาน
       Compressed air enter the ejector through compressed air supply port P, passes through the nozzle and diffuser at high speed and sucks air out of the vacuum, generating port V, thus creating a vacuum in the sealed chamber to which V is connected.
