Features

  • The two-stage exhaust system has lower pressure (good vacuum) than the one-stage exhaust system.
  • Low noise and low vibration.
  • The backflow prevention mechanism prevents oil from flowing back to the vacuum chamber when it is stopped due to a power failure.
  • The exhaust speed is stable due to the installation of the forced oil supply mechanism.
  • Operation from atmospheric pressure is possible.
  • Easy connection by internal components knock pins and maintenance by flange motor.

Applications

  • Chemical science experiment, Analyzer and Laser system
  • Vacuum pumping system
  • Back pump for the electronic microscope
  • Semiconductor equipment, sputtering equipment, vacuum evaporation equipment
  • Vacuum dryer, freeze dryer
