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 .
