The present invention relates to a vacuum system (1) for a sterilisation equipment without the use of water and not limited to saturated steam, particularly for use in equipment for sterilising medical implements for clinical, hospital or similar use. The vacuum system (1) is formed by a vacuum pump (2), a vacuum inlet valve (3), an atmospheric air inlet valve (4), an atmospheric pressure stabilisation valve (5), a discharge valve (6) connected in series to the thermostatic valve (7) for removing condensation in the conditioning and heating phase, wherein valves (3) and (4) are connected to the inlet of the vacuum pump (2) through a curved duct (8) to prevent the condensation generated from entering the vacuum pump (2).
