Designed pumping capacity: Theoretical value calculated from cylinder volume. Refer to "Performance Data" for actual flow rate.
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 normal 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.
Recommended range of combined vacuum and pump pressures: 60 or lower.
Maximum vacuum/pressure per pump can be any combination of the following (vacuum/pressure): 55/20, 55/30, 40/40, 35/50. The maximum vacuum/pressure of the dry pump indicates the maximum sustainable vacuum/pressure. Do not operate the pump beyond this maximum value. Doing so can reduce the lifespan of the pump and may result in breakdown or an accident.

Please consult with your dealer regarding operation in extremely dry environments, as doing so may lead to pump damage.
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.
When using other than the ORION standard motor, follow the electrical guidelines printed on the nameplate of the motor used.
Please install an overload protection device (such as a thermal relay).

If detailed specifications are required, please Contact ORIONc to request a specifications sheet.
