Technological       innovation 

The technique that 2PB series of high-pressure fan used in Fenglishi are derived from the German sub-fluid machinery technology, all of which are formed by ADC12 aluminum diecasting. After processing by high-precision CNC machine tool, the motor insulation level can be reached at H, and the temperature resistance can be up to 180 degrees. There are more than 100 kinds of 2PB series of high-pressure fans produced by Fenglishi. They have huge flow and are particularly power-saving and durable. They are extremely tight, efficient and environment-friendly, they also have UL certification, which makes them much better than other high-pressure fan products on the market. 2PB series of high-pressure fan products are used in combination with blowing and suction, which can realize the functions of air supply, dust suction, exhaust, cooling, transportation, air cushion, etc., and can be applied to environmental protection equipment, water treatment equipment, industrial printing equipment, food packaging equipment and breeding production equipment. Fenglishi uses bearings from C&U Group, which is specialized in making bearings, and uses a one-time processing method to ensure that the entire machine components are running on the basis of concentric circles, with low resonance and low deflection. Under the same power, the performance will be improved by 30%~50% compared with other similar products, and it can be changed to the original Japanese NSK bearing if customers need. The fan in Fenglishi has excellent performance and long life. It can greatly increase the added value of your equipment, it’s perfect for you to solve all production troubles!
