Francis fan is between axial fans and centrifugal fans among fans, Francis fan impeller centrifugal motion to allow air to both do and do axial movement, the movement of air shell axial and centrifugal mixing the two movements in the form of so called "Francis." Francis (oblique flow) fans, axial fans higher than the pressure coefficient Francis fan how selection, big difference Francis fan and exhaust fan flow coefficient than the centrifugal fan, with the pressure and flow are "clique" of occasions. It fills the gap between axial fans and centrifugal fan of. Along with easy installation features. Francis turbine combined axial and centrifugal fan characteristics, shape looks more like a traditional axial fans. The housing may have an open inlet, but more often the case, it has a shape bent at right angles mixed flow fan, the motor can be placed outside of the pipe. Excretion shell slow expansion to slow down the speed of the air or gas flow, and the kinetic energy is converted into useful static pressure. The basic structure type air-conditioning plant in Texas Hongxin Francis fan for air inlet and outlet on the same axis (ie axial flow structure) What is the Francis turbine wheel shell as cones, leaves were ranged along the width of the flow state.
