FIELD: agriculture and industry.
SUBSTANCE: invention can be used in agriculture and industry to provide higher operating capabilities of fan within the range of energy-saving control of mode of operation. According to invention proposed cross-flow fan contains housing with intake and outlet holes and flat wall separating the holes and equipped with louvers, and impeller installed in housing. Louvers of flat wall are made curvilinear forming contraction-recirculation channels pointed by outlet section to impeller of fan. Louvers mating with flat wall are installed on hinge joints and adjoin by other end over contraction-recirculation channels and impeller.
EFFECT: improved operating capabilities of fan.
