Introduction With the venturi tube as the essential component, the venturi pneumatic transmission equipment sucks the powder or particles into the transporting pipeline by means of venturi effect for further transmission. The transmission has flexible directions, able to transport simultaneously with discharge.   Characteristics 1. No dust flying, no leakage or blockage 2. Strong transmission ability and long conveying distance 3. Transmission simultaneous with discharge can be realized 4. Total pneumatic control, easy for automation 5. Reliable operation with no moving parts
