Mixed-flow fan is between the axial flow fan and centrifugal fan between the fan, mixed-flow fan impeller so that the air to do both centrifugal movement and axial movement, the movement of the air in the shell mixed with the axial flow and centrifugal two kinds of movement methods, so called "mixed flow". The structural characteristics of the mixed flow fan are mainly composed of impeller, casing, inlet collector, guide vane, motor and other components.

Mixed-flow fan is between the axial flow fan and centrifugal fan between the fan, mixed-flow fan impeller so that the air to do both centrifugal movement and axial movement, the movement of the air in the shell mixed with the axial flow and centrifugal two kinds of movement methods, so called "mixed flow". The structural characteristics of the mixed flow fan are mainly composed of impeller, casing, inlet collector, guide vane, motor and other components.

The impeller selects several distorted wing-shaped blades with meridional acceleration characteristics and is welded on the conical hub. After dynamic balance check and overspeed test, it has outstanding aerodynamic performance. The casing is cylindrical and connected with a current collector with silencer function to form a whole body. The air outlet is equipped with a guide vane, which has excellent airflow distribution and stable pressure.

The mixed-flow fan is designed with secondary air intake to reduce the ambient temperature of the motor. The use of mixed flow fan places: can be used in tunnels, underground garages, metallurgy and other high temperature smoke exhaust places, in the case of fire, can be agile smoke cooling, assist firefighters to enter the disaster area in time to put out the fire, is a necessary facility for fire safety.

Can transport gas mixed flow fan transport gas varieties: air and other non-spontaneous combustion, harmless to the human body, non-corrosive gas to steel, in special environments, can choose explosion-proof mixed flow fan. The main points of the mixed flow fan device method can be divided into vertical and horizontal. The main points of the mixed-flow fan installation: when the fan is installed, all parts shall be fully checked, whether the parts are complete and whether the parts are connected tightly.
