Designed pumping capacity: Theoretical value calculated from cylinder volume. Refer to "Performance Data" for actual flow rate.
Pump can be continuously operated at the maximum attainable vacuum.
Operating noise level measured on a new pump with the standard built-in ORION motor. Operating noise levels are from a position of 1 m in front of the unit and at a height of 1 m.
Please consult your dealer regarding continuous operation at levels on the dotted lines in the performance data charts.
Maximum operational pressure variation pulse: 13.3 kPa (abs] Is.
Allowable back pressure for exhaust ducting: 10 kPa or lower. (This pressure should not be used for any other purpose.)
Operating environment inlet air conditions: air temp: 0 to 40 ℃, humidity: normal levels (65+20%).
Due to the high compression ratios found in high-vacuum pumps, condensation can easily form within the pump. Therefore the following measures should be taken in order to avoid trouble from rust due to condensation: During a trial run (operation of 5 minutes or less, such as a momentary operation or short test run) if the operating pressure goes above 48 kPa (abs], then a dry run of 10 to 15 minutes should be made at a pressure of 48 kPa (abs] at the vacuum side of the pump.
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).
Single phase models require pre-order.
If detailed specifications are required, please contact ORION to request a specifications sheet.
