How to Choose an Air Purifier Cooling Fan
2024-10-08
At present, there are mainly two types of fans used in air purifiers on the market: centrifugal fans and axial flow fans. For centrifugal fans, the air flow enters from the fan shaft. The air is blown away, creating a vacuum in the fan casing and sucking in external air. The air volume and pressure are relatively large. Axial flow fans are fans with the same axial direction as the air and blades. The air volume and pressure are relatively small.
Most air purifiers are based on the technology of filtration devices. It is just a combined cooling fan filter. During operation, the cooling fan of the fuselage stirs the indoor air. Through the function of the fan, the particulate matter in the air is adsorbed on the filter device, reducing the particulate matter in the air and achieving the purpose of purifying the indoor air. Thus, it can be seen that the key of an air purifier lies in the arrangement of the filter and the fan. The quality differences of many products also depend on the number of layers of the filter, the material, and the quality of the cooling fan.
The fan is the spear of an air purifier. Choosing a suitable fan is crucial. High-performance air purifiers mostly have thick activated carbon and multi-layer non-woven fabric filters. The resistance of such filters is a major challenge to the performance of the fan motor.
So, how do we choose an air purifier cooling fan? As of now, centrifugal fans are the best fans for manufacturing air purifiers. The service life is divided into oil-containing fans and ball bearing fans, with service lives of 20,000 hours and 50,000 hours respectively. Generally, we recommend that customers use double ball bearings. Because the weather is extremely hot in summer, if the temperature is too high, the internal lubricating oil of the oil-containing bearing fan will dry up quickly, and the fan noise will be very loud.
