Application
The biggest characteristic of the cross flow fan is that the fluid flows twice through the fan impeller . The
fluid flows in the radial direction and flows along the radial direction. The intake and exhaust directions
are in the same plane , and the exhaust gas is evenly distributed along the width of the fan . Because of
its simple structure , small size , high dynamic pressure coefficient to achieve a longer distance , widely
used inlaser instruments , air conditioning , air curtain equipment , dryers , hair dryer , household
appliances and grain combine harvesters .
