Robust design features

Dependable new gas system with manual gas ballast control with sleek sheet metal protective enclosure.

Simple electrical strategy

In-built, off-shelf inverter for simple connection and communication. Protection sensors fitted, electrical design for reliability and safety.

Low power and utilities consumption

The EXS has a low carbon footprint thanks to its low power and utilities usage. With no contaminated or dirty disposable oil, it is also easy on the environment.

Increased roughing speeds and low ultimate performance

Gain increased productivity with faster processing and pump down times; low ultimate pressures up to <1 x 10-2 for dry screw vacuum pumps and <1 x 10-3 for pump plus booster combination.

Non-contacting long-life seals

Non-contacting long-life seals with integral oil blocking labyrinth seal provides highly effective sealing.

Advanced Core technology

Advanced quality bearings and special purpose oil with low vapour pressure for application compatibility.

Detailed data insight and easy control

A wide variety of connectivity solutions including I/O, Fieldbus communication, IoT allow the real time detailed insight and access of the pump.
