The foreline connection should be made using the KF 16 NW flange provided on
the TwisTorr 305-IC. The connection to the foreline pump can be made by a

mechanical pump must be damped through the use of bellows.
The TwisTorr 305-IC is characterized by its high compression ratio also for oil

suitable trap between the turbopump and the fore-vacuum pump in order to
prevent back streaming oil or particulate from dry pumps.
