The reversal of the air jet is carried out by simultaneously turning the blades of the straightening apparatus by 90 ° and changing the direction of rotation of the rotor (motor). Design: The VOM-18 fan consists of a housing, a straightening device, a rotor, a drive for the impeller blades rotation mechanism on the move, a drive for a rectifier blade rotation mechanism, a drive motor on a rack, a clutch, a diffuser, a gate device with a drive, a hand brake and a common foundation a frame that is bolted to a stationary foundation, an air flow and pressure measurement station.
