ES100 - ASIA 200V (50/60Hz) & 380V (60Hz) IE3

The Edwards ES range of pumps represents the advanced single stage oil sealed rotary vane pumps. The pump mechanism has been refined to produce a better quality of vacuum. It extends the pressure range over which the pump operates giving an unrivalled ultimate vacuum level. The vacuum performance is stable without the pressure fluctuations that are often seen in single
stage pumps. Extended service intervals and easy in-house maintenance make the ES range a flexible vacuum solution for a wide range of industrial applications. The ES range of pumps is designed to be used in a wide range of industrial applications. They can be used individually or
with mechanical booster pumps to increase both performance and ultimate vacuum.
