Currently, there are two main types of fans on the market: Centrifugal fans and axial flow fans, said air purifier, a professor of electrical engineering at the University of California, Berkeley, who was not involved in the study. Axial flow fans are fans such as electric fans with the same axial direction as air and blades, but the air volume and pressure are relatively small. Centrifugal Fan air flow from the fan shaft into, the air is blown away, the fan shell into a vacuum, the inhalation of external air. The air volume and pressure are relatively large. The air purifier is largely based on the technical nature of the filter, which consists only of a cooling fan filter screen. Work on the body of the micro-cooling fan to stir indoor air, according to the efficiency of the cooling fan so that the gas in the object-like material in the filter device, reduce the gas in the object-like material, achieve the goal of cleaning indoor air. The key to the air purifier is the placement of filters and fans. The quality of many products also depends on the filter layer number, material and cooling fan quality fan air purifier is the spear, choose the right fan is very important. Most of the air purifiers with strong performance have thick active carbon and multilayer high-rise filter without cloth. The friction resistance of this filter is a big challenge to the performance of Fan Motor. High-quality air purifier fan motor, to ensure that more than PA shell resistance can also output a lot of cleaning gas, in addition, must cause as low as possible noise. Centrifugal fans are by far the best fans for air purifier. Because not only can get rid of high-efficiency object filter device + activated carbon generated by the great friction resistance, can output clean gas. Perhaps, even if the front or side of the application of the cooling fan, filter must be designed to give full play to the wind path structure to play a greater role, in addition to low noise. http://www.dxymotors.com
