Specifications
※1 Models without motors are excluded.
※2 Designed Pumping Capacity: Theoretical value calculated from cylinder volume. Refer to Performance Data” for actual flow rate.
※3 Operation not allowed at ultimate vacuum.
※4 Range of operable degree of vacuum (or exhaust pressure)
※5 “04” models are special order items.
※6 Operating noise level measured on new pump with ORION recommended motor running at normal vacuum/pressure conditions. Allowable ambient (intake air) conditions: temperature: 0 40 , humidity: 65 20%. Allowable variation in power source voltage: 10% of rated voltage. Install overload protection such as a thermal overload relay. For specific setting of the relay, refer to current rating indicated on the motor’s specification plate. Set at 110% of the rated value for B and VB models. See specification sheet for further details.
