The radial fan - the fan, in which the direction of meridional speed of a stream of gas on an entrance to the driving wheel in parallel, and at the exit from the driving wheel perpendicular to an axis of its rotation. Depending on the size of the total pressure created in the nominal mode in accordance with GOST the 5976th fans are divided on:
Centrifugal low pressure - providing a total pressure to 1000 Pas (to 100 kgfs/sq. m)
Centrifugal average pressure - from 1000 to 3000 Pas (from 100 kgfs/sq. m to 300 kgfs/sq. m)
Centrifugal a high pressure - from 3000 to 12000 Pas (from 300 kgfs/sq. m to 1200 kgfs/sq. m)
