The transportation or dosing of granulated materials with the help of compressed air or different propellants is called pneumatic transport or pneumatic transport. The working principle of the pneumatic conveying system is based on the logic of transferring the kinetic energy of the compressed air flow to the granular product to be transferred. In pneumatic transfer processes, each product carried with the help of compressed air is mixed with air and then separated from the air. Mixing is done with the help of rotary valves (airlock), loading stations and venturi, while separation is done with the help of filters. Unlike the method of transport of pneumatic transfer systems with the help of compressed air, the transport systems realized by using the power of the vacuum produced by the vacuum pump are also called vacuum pneumatic transport systems.

Compressed air, which is the basic need of pneumatic conveying systems, is provided with side channel blowers, roots blowers or high flow fans depending on the capacity and flow of the air needed by the system. Although pneumatic conveying systems seem to be mixed with compressed air and then separating the product with the help of a filter, it is a work that requires serious engineering work and experience. Dusts to be transported can gain high explosive property under a certain pressure and temperature. Products such as sugar, flour, starch, which seem extremely innocent can become extremely dangerous products with their incorrect design and selection.
