Air suspension blower is an environmentally friendly blower produced by turbine engine technology. It mainly rotates the rotor at high speed to produce dynamic pressure effect between the rotor and the surface of the foil bearing, forming a high pressure air film to float the rotor. Air suspension centrifugal fan not only has the advantages of energy saving and high efficiency, low noise, small size, easy installation, high system integration, simple use, easy maintenance, low cost, long life, etc., but also has the advantages of energy saving and environmental protection, no vibration, low noise, no lubricating oil, no maintenance, convenient operation control, simple maintenance, etc., so that it has broad prospects for use and can be widely used in different industries. For example, it provides air for different processes such as water treatment, paper and printing, chemical industry, food and beverage, pneumatic conveying, electroplating and power generation desulfurization, and also provides convenient conditions for production efficiency and cost reduction and product quality improvement in these industries.
