Rugged vacuum pumps for industrial applications

LEYVAC dry screw vacuum pumps are a class of industrial vacuum pumps based on the screw principle. The LEYVAC series from Leybold is especially developed for the process industry, food and process applications, coating and display applications. They can simply be assembled by adapters to various vacuum systems, particularly the well-proven RUVAC WH700 and WS(U) and WA(U) series.

User advantages

No oil contact to process gases

High pumping speed for air and H2 already at high pressures

Hermetically tight

Robust and durable design

One motor solution

Easy and modular
