[SWF (B)] Series Low Noise Francis fan is between saving a new fan axial and centrifugal fans between its high pressure centrifugal fans, axial fans high-volume, high-efficiency saving a good selection and installation of centrifugal fan, low noise, easy installation and so on. When this series centrifugal blower fan design Ying distinguish left and right hand, compact structure, small size, light weight, easy to install, and old-fashioned compared to centrifugal fans can save 20%, speed is less than 2000r / min, noise below 75dB (A), the fan connection pipes and install air conditioning inside the fan noise of less than 70dB (A). Can replace 2000pa below, the low-pressure centrifugal fans, axial fans are widely used in industrial water-resistant cap, dust and other civil ventilation. The centrifugal fan is to rely on mechanical energy input, increase gas pressure gas side mechanical transmission, it is a slave fluid machine. Centrifugal fans are widely used in factories, ventilating mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the wind; air-conditioning equipment and household appliances and cooling equipment ventilation; grain drying and sending; wind tunnel source and inflatable hovercraft and propulsion.
