Pneumatic conveying is a process that uses air to transfer bulk product such as powders, pellets, and other solids from point A to point B within piping or tubing. Successful conveying of material relies upon air flow between the starting and endpoints of the system. Flow is typically achieved using a blower, compressor, fan, or vacuum pump.

Sand can be transported using either pressure (positive) conveying or vacuum (negative) conveying. For the former, compressed air is used at the start of the system to push the sand through the piping. For the latter, it is "sucked" toward its destination.
