Here, I will tell you about the unknown story of the use of cooling fans in air purifiers, fans, blowpipes and leather bags. Fans and blowpipes were used for forced air blowing in the early days. Ancient Egyptian goldsmiths used blowpipes with pottery nozzles, and the Incas sometimes used 8 to 12 copper pipes to blow at the same time. Later, a blowing skin bag made of animal skin was invented, and the two ends of the bag were respectively equipped with air ducts and air inlets controlled by the grass writer. This crude blower is still used in some areas in modern times. The image of pot-shaped pedal blowers has been painted in the murals of the tomb of Rekhmir (about 1450 BC) in the eighteenth dynasty of Egypt. When the wind comes in, the grass writer uses a rope to pull up the leather bag, and then steps on it to blow the wind into the furnace. Each furnace is equipped with four blowers, and two people face each other to work. This is the origin of the ancient air purifier cooling fan.
For now which fan is used in household air purifier? Centrifugal Fans/Blower Fans.
They are mostly responsible for the suction of dusty air and its swift movement into the filter, and then out, already cleaned. The blades are mounted around a hub and on a shaft, which is where the blades are turned from.
Xingdong DC Blower 12/24V 120*120*32mm is suitable for household air puriffer, high air volume, strong ventilation capacity.
