- Designed Pumping Capacity: Theoretical value based on volume. Refer to performance data for actual flow rate.
- Operation not allowed at ultimate vacuum. For model selection purposes only.
- Operable range of vacuum (exhaust pressure).
- '04 models are built-to-order items.
- Actual operating noise measured on a new pump with the ORION recommended motor running under normal and 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).
