The main goal of the research was to design and build a prototype of device used for pneumatic transport, which will increase the difference of pressure in the pipeline and will increase velocity of the airflow during the transport of materials over different distances. During design process of the device using graphics software assumes that the system of separation of grain and air should be eliminated. The device is applicable in systems that need additional air amplifier, without the cyclone-filter system. The results confirmed that in the rearmost point of the pipeline dynamic pressure was lower than the pressure at the nearer measuring points. In addition, analysis of the transported grain did not show his deformation. During the test of the device only a slight increase in the temperature of the transported material was noted.
