The wind direction and the axis is parallel to the axial fan called dz low noise axial fan, (such as firefighting exhaust fan) and vice versa is a centrifugal fan, fan blades and motor combination can be sized according to the most amount of wind pressure. General axial fans centrifugal fan than an advantage in portfolio selection and a large amount of wind pressure on the (mainly refers to the fan efficiency and noise performance)! Centrifugal fans and axial fans difference is: 1, changed the flow sf3-4 centrifugal fan axial fan duct inside the medium, while axial fan does not change the flow of the medium within the duct; two, the former air volume and pressure are great jobs shaft flow fans, the former air volume and pressure are very low; 3, the former is more complex installation, which is relatively simple to install; 4, the former motor and fan are generally connected by a shaft, which is generally within the fan motor; 5, the former often install In the air conditioning unit inlet and outlet of the boiler drums, Fan, etc., which were often installed in duct or duct outlet front-end low-noise axial fan all made of high quality steel, exterior structure is divided into pipeline, fixed, rotary three widely used in industrial and mining enterprises, workshops, warehouses, laboratories, office buildings, stadiums, hotels, restaurants and other civil ventilation can also be connected in series or in parallel to increase the pressure between the pipe, ventilation and air flow. The fan should convey a non-flammable non-corrosive, non-significant dust of gas, the gas temperature must not exceed 60 ℃.
