Air suspension centrifugal blower has the characteristics of energy saving, low noise, no oil, reliable operation, easy operation and maintenance and semi-permanent life. Used in sewage treatment industry, food and drug industry, petrochemical industry, cement building materials industry, metallurgical textile and other industries.

Four core technologies: self-acting dynamic pressure air bearing with flexible surface support, with long operating life, high reliability, good stability, strong bearing capacity, high temperature resistance and so on. Air mold support, no lubrication required. Avoid air secondary pollution, almost no power loss, energy saving effect is obvious.

The existence of coulomb friction in the dynamic pressure air bearing inhibits rotor vibration, and the rotor amplitude is less than 0.02mm. The rotor has passed 20,000 start-stop tests and is a semi-permanent bearing in the true sense.

New impeller: the material selection of the impeller is 7075, and the coating technology can achieve stable operation at ultra-high speed. The five-axis machining center is made of precision machining, using the three-way flow design concept, the variable efficiency of the impeller reaches 92%, and the impeller passes the 115% overspeed test.

High speed permanent magnet motor: Using advanced motor air cooling technology, the motor efficiency can reach 97%. Frequency conversion speed regulation, high efficiency and energy saving, simple overall structure, high power density, large banner range, strong overload capacity, high reliability.

Automation system: The use of motor and inverter speed control system, PID automatically adjust the air volume and pressure, so that the fan within the working range to achieve economic operation state. The control system self-checks the speed, wind pressure, air volume, temperature, etc., and has the function of anti-surge and alarm automatic shutdown. Panel control is easy to operate, all data at a glance, with manual and automatic operation

As a function. The control system can complete no-load start-up through the empting device, and realize safe shutdown in the case of power failure and alarm.
