The utility model discloses a pneumatic vacuum system which comprises a box body, and an air inlet pipe, a pressure regulating valve, a ball valve A, a ball valve B and a vacuum pipe are fixed on the box body. A vacuum generator, an air outlet pipe and a vacuum tank are arranged in the box body; the air inlet pipe, the pressure regulating valve, the ball valve A, the vacuum generator and the air outlet pipe are sequentially connected; the vacuum tank, the ball valve B and the vacuum pipe are connected in sequence. Compressed air enters through the air inlet pipe, air inlet pressure is controlled through the pressure regulating valve and enters the vacuum generator, air inlet positive pressure is converted into vacuum negative pressure, vacuum negative pressure is formed in the vacuum tank, and meanwhile air of the vacuum generator is exhausted through the air outlet pipe. When vacuum negative pressure of the vacuum tank is applied, the ball valve B is opened, an external adsorption device is connected through
