Connection of the Fore-Vacuum Pump

The foreline connection should be made using the KF 16 NW flange provided on
the TwisTorr 305 FS. The connection to the foreline pump can be made by a
vacuum rated hose or pipe. If a rigid pipe is used, any vibration generated by the
mechanical pump must be damped through the use of bellows.
The TwisTorr 305 FS is characterized by its high compression ratio also for oil

vapors. When using a mechanical oil-sealed pump, it is advisable to install a
suitable trap between the turbopump and the fore-vacuum pump in order to
prevent back streaming oil or particulate from dry pumps.
