Booster pumps can be used with roughing pumps, such as oil rotary pump, dry vacuum pumps, and water sealed pump, in order to improve the pumping speed in the 1300-0.13 Pa range, where pumping speeds of roughing pumps often deteriorate.
NB series are roots-type vacuum pumps designed primarily for use in processes where a high level of cleanliness is required.

Application:
Illuminant, electronics, optics, semiconductor,
Evaporation, sputtering, ion plating, liquid crystal injector
Vacuum drying, freeze drying, vacuum degassing
Vacuum heat treatment furnaces, sintering furnaces, brazing furnaces
Analytical instruments, leak testers, CO2 laser equipment
