Dry Compressing Vacuum Pumps
Dry vacuum pumps are dry compressing pumps where no lubricants can get into contact with the pumping media. Thus an absolute hydrocarbon free vacuum is the result. Leybold offers different types of dry compressing vacuum pumps which vary in the principle of operation and are used in different fields of application: diaphragm pumps DIVAC, scroll pumps SCROLLVAC as well as screw type pumps SCREWLINE and DRYVAC.
LEYVAC
Screw Vacuum Pumps
LEYVAC vacuum pumps are dry compressing fore vacuum pumps, the operation is based on the screw principle. The LEYVAC series is especially developed for process industry, F&P, coating and display applications. They can simply be assembled by adapters to various vacuum systems, so particularly with regard to the well-proven RUVAC WH700 and WS(U) and WA(U) series.
