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 .
