- Designed pumping capacity: Theoretical value calculated from cylinder volume. Refer to "Performance Data" for actual flow rate.
- Operation not allowed at ultimate vacuum.For model selection purposes only.
- Operable range of vacuum (pressure).
- "04" models are special order items.
- 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).
- See specifications sheet for further details.
- If detailed specifications are required, please Contact ORION to request a specifications sheet.
