The Kashiyama NeoDry 15C employees multi-stage Roots roughing pump technology to achieve a totally clean dry vacuum. The NeoDry produces a clean dry vacuum thanks to its frictionless design. Unlike scroll pumps, the NeoDry does not have tip seals that wear and generate particulate dust. The highly reliable design of the Kashiyama NeoDry vacuum pump allow dry vacuum at lower cost of ownership; they not need routine tip seal replacements.
