PURPOSE: A portable pneumatic vacuum cleaner is provided to prevent the surface damage of a filter by enabling the air and a foreign material guided into an inlet part not to be contacted with a filter. CONSTITUTION: A portable pneumatic vacuum cleaner includes a body(110), a discharge tube(120), a separator(130), a filter(140), and a curved plate(150). In the body, an inlet part(111) where the air flows into and an outlet part(112) where the air is discharged are formed. The discharge tube is connected to the outlet part in one side of the body. The discharge tube passes compressed air from one end to the other end and guides the vacuum suction of the air through the inlet part of the body. The separator divides the inside of the body into an upper space and a lower space and includes a penetration hole(131).
