Features

  • A standard type of dry vacuum pump with abundant results and low price.
  • Dry vacuum pump using no oil in the gas contact area.
  • Rich lineup available to suit your application.
  • One-stage exhaust system is faster than two-stage exhaust system.
  • Safety design with built-in automatic reset type thermal protector.
  • Operation is possible from atmospheric pressure.
  • Simple structure and easy maintenance.
  • By incorporating an unloader valve (Option), air can be introduced into the pump when the pump is stopped, and the pump startup characteristics can be improved.
