1) Screw element
Latest oil-lubricated screw profile
Durable design with high performance
2) High efficiency permanent magnet motor IE5
PA series is equipped with a permanent magnet assisted synchronous reluctance motor. The characteristic of this motor technology is to have particularly high efficiencies at all speeds, which makes it perfectly suited for variable speed. The efficiency of this motor is equivalent to IE5. The motor is cooled by the oil of the pump, ensuring an optimal cooling at all speeds. Another great advantage: the motor bearings are also lubricated by the oil, no need to regrease them at regular intervals. There is no extra fan on the motor which means less power consumption and less noise. This also results in a compact design.
3) Variable Speed Drive
With the Neos Next inverter combined with set-point control, the pump delivers the pumping speed needed for the process. With these vacuum pumps you can potentially save 50% or more in energy costs. Oil-injected rotary screw vacuum pumps are also the ideal technology to combine with variable speed drives as they have the largest turndown ratio on the market; offering the largest range of pumping speed on the same model. In addition, the buildup in a separated cubicle ensures efficient heat dissipation.
4) Cyclonic oil separation
PA series benefits from excellent oil carryover thanks to its cyclonic design. The cyclones efficiently separate oil from the air by centrifugal force. The oil separator elements then carry out the last separation step. This leads to an oil discharge at the exhaust that is lower than 1.5 mg/m³.
