※1 - Designed Pumping Capacity: Theoretical value based on 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 (exhaust pressure).
※4 - '04 models are built-to-order items.
※5 - Actual operating noise measured on a new pump with the ORION recommended motor running under recommended vacuum/pressure conditions. Operating noise level is from a position of 1 m in front of the product and at a height of 1 m.
  • Operating environment (inlet air) conditions: air temp: 0 to 40 ℃, humidity: normal level (65±20%).
  • The allowable intermittent power supply voltage fluctuation range is ±10%, and the allowable sustained supply voltage fluctuation range is ±5% of the specified voltage.
  • Please install an overload protection device (such as a thermal relay). Setting: Use the current rating listed on the motor nameplate as a guide when setting the protection device. Set at 110% of the rated value for B and VB models.
