How to choose air purification centrifugal fan

- May 27, 2019-

Air purification centrifugal fan products are basically using filtration technology, which is simply a combination of air purification centrifugal fan + filter. The micro-fan in the machine stirs the indoor air, and under the action of the fan, the particulate matter in the air is adsorbed on the filter net, so that the particles in the air are decremented to achieve the purpose of cleaning the indoor air. It can be seen that the key to the air purifier is the filter and the fan. For most products, the difference in quality depends on the number of layers, materials and fan quality.


The air purification centrifugal fan is the core of the air purifier, and it is important to choose the right fan. A powerful air purifier often has heavy activated carbon and a multi-layer non-woven filter. The resistance generated by these filters is a challenge for the performance of the fan. The air purifying centrifugal fan used in an excellent air purifier must ensure that a large amount of clean air can be output under the resistance of several hundred Pa of working conditions, while generating as low a noise as possible.


Air-purified centrifugal fans are the preferred fan for air purifiers. Because it can not only overcome the huge resistance caused by high-efficiency particulate filter + activated carbon, but also can still output considerable clean air. Of course, whether you use a forward or backward centrifugal fan, you need to specially design the air duct structure to maximize its effect and produce lower noise.
