1) our new invention is suction vacuum regulator to control the pressure of the suction vacuum through the centralized medical gas pipeline system. The pressure regulation ranges from 100 to 600 mm of hg (for patients use). 2) back entry pressure gauge indicates the controlled pressure which is manually set (0-760 mm of hg)3) built in probe (safety keyed plug vacuum) makes it redundant to procure it separately, using spectra double lock outlet. 4) the jar assembly (600 m capacity) is meant for accumulation of sucked fluid made of polycarbonate to be fitted directly with the ecovac regulator. 5) no bracket is required for fixing6) no tubing is required to connect the jar with the regulator7) no probe (safety keyed plug vacuum) is required
