A 510 MeV high luminosity @PHI@-factory is operating at INFN Fascati National Laboratory, Italy. The accelerator complex consists of a full energy Linac, a small damping ring and a double electron-positron high current storage ring. We describe in the following the main rings vacuum system. The design is based on the requirement of 1x10@super -9@ mbar as dynamic pressure with a gas load of about 1x10@super -4@ mbar l/s per ring. The main features of the vacuum system are: all metal aluminum vacuum chamber with proper surface finishing; special alloy bolt set; monolithic water cooled copper synchrotron light absorbers; high capacity titanium sublimation pumps; lumped and distributed sputter ion pumps and high capacity non evaporable getter pumps.
