SWF series mixed flow ventilator
Model SWF mixed -flow ventilator is a novel and intermediate fan between axial-flow fan and centrifugal fan .It absorbs gas from both fans .Its wind pressure is higher than the same machine number axial-flow fan and flow larger than the same machine number centrifugal fan .It has the advantages such as wide and effective operational zone , high efficiency etc. This fan is widely applicable for the ventilation and exhaust system in the office building ,hotel . Large-size high-grade civil purpose architectures etc. It can also be used for ventilation and air-exchange in the mining and industrial enterprise such as freezing house , textile and so on in order to replace for the low-pressure centrifugal fan or high-pressure axial -flow fan with no need to install large amounts of the noise blanking facilities.
