  1. Designed pumping capacity: Theoretical value calculated from cylinder volume. Refer to “Performance Data” for actual flow rate.
  2. Operation not allowed at ultimate vacuum. For model selection purposes only.
  3. Operable range of vacuum (pressure).
  4. “04” models are special order items.
  5. Operating noise measured on a new pump with an ORION recommended motor running at the recommended vacuum/pressure conditions. Operating noise levels are from a position of 1 m in front of the unit and at a height of 1 m.
  • Operating environment (inlet air) conditions: air temp: 0 to 40 ℃, humidity: normal level (65±20%).
  • Allowable intermittent power supply voltage fluctuation range is +10% of the specified voltage, allowable sustained supply voltage fluctuation range is +5% of the specified voltage.
  • Please install an overload protection device (such as a thermal relay).
