2.8 External evacuation system

The pumpdown performance on dry pumping systems fitted with mechanical boosters
can be further enhanced by the use of an External Evacuation System (EES) kit. The EES
kit will only provide performance improvement on pumpdown cycles lasting less than
30 seconds to pressures below 0.1 mbar. The EES kit must only be used on clean
applications.
