1. The fan impeller and shaft adopt an integrated structure with good rigidity, ensuring high pressure, large flow rate and stable operation of the fan at high speed;

2. The fan oil tank is made of aluminum alloy and has an air-cooling structure. The single-stage pressure is 98kPa without cooling water;

3. Intensive unit design, compact structure, self-tensioning belt tensioning structure, easy to use and maintain;

4. The fan host can be used both vertically and horizontally, and can be easily replaced with foreign models;

5. It adopts precision hardened helical tooth synchronous gears, keyless connection, reliable positioning, smooth operation, low noise, high strength and long life.
