There are also mixed flow (Francis) fan axial fans offer, high pressure coefficient than the axial fan axial fan 380, flow coefficient than the centrifugal fan. To fill the gaps between axial fans and centrifugal fans of. Along with easy installation features. Francis (or axial-flow impulse) fan combines axial and centrifugal fans feature, although it looks more like a traditional axial fan. The curved plate-shaped blades welded to the conical steel hub. By changing the angle of the blade inlet in the housing upstream of the impeller to change the flow. Cabinet can have open inlet, but more often the case, it has the shape of a right angle bend axial fan, the motor can be placed outside of the pipe. Excretion shell slow expansion to slow down the flow of air or gas, and the kinetic energy is converted to useful static pressure. Due to the general low number of revolutions of the motor axial fan, motor power, with a lot more power. If ventilation systems usually used, as far as possible cabinet centrifugal fan, fire smoke unusual system, using high temperature axial fan is more economical! Centrifugal fan axial fans than the combined amount of wind and a large selection pressure on the advantage (mainly referring to the fan efficiency and noise performance)! Centrifugal fans and axial fans Axial fans difference is positive outlet, rich ventilation equipment (certified), axial fans are provided by Shandong Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (www.frtfsb.com) (www.frtfsb.com) is a leader in Dezhou, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum limits to meet customer needs.
