Multi-stage blowers have a wide scope of applications in terms of pressure increment of up to 1 bar and capacity of 50.000 m3/h. They have a series of strong points and are competitive for other blowers. As part of research and development works very comprehensive analyses of variants of solutions are conducted for the purposes of determining of a concept of series of types, which involves indication of diameters and number of stages, which should be used for obtaining of set values of efficiency and pressure. Preliminary proposals have been established. A program of experimental and theoretical tests was also established.
