The Edwards HV8000 high vacuum mechanical booster has been developed to provide high reliability operation in aggressive environments.
With a nominal pumping speed of 7200 m3h-1 (4241 ft3 min-1) at 50Hz, it is ideal for large industrial and chemical applications including, steel degassing, metallurgy, coating, electron beam welding and the process engineering industries.


Features and Benefits

  •     Derived from the successful range of HV pressure blowers, the HV8000 is designed for arduous duty cycles and high power applications.
  •     Ideal for larger scale, harsh industrial and chemical applications, the HV8000 is available in Industrial, ATEX or Explosion Proof configurations.
  •     The HV8000 may be ordered as either bareshaft or with motor fitted. Variable frequency drives may be specified for greater versatility.
  •     The HV8000 is available in vertical or horizontal gas flow configuration.
  •     For long service life, the external shaft seal is water-cooled.
  •     Five bearing construction and large capacity helical gears make for a very robust construction.
  •     Suitable for use in explosive atmospheres
