  Centrifugal Fan

  Centrifugal fans are a type of fan widely used in industrial ventilation systems. They have the remarkable characteristics of compact structure, stable performance and strong adaptability. Its working principle is to inhale air from the center of the fan through the high-speed rotation of the fan impeller, and then throw the air to the periphery through the centrifugal force of the impeller, thereby generating a higher wind pressure. Compared with axial flow fans, centrifugal fans can provide greater pressure and stronger air flow delivery capacity, and are particularly suitable for occasions that need to overcome large pipeline resistance and system pressure. Centrifugal fans have various impeller designs, including forward-inclined impellers, backward-inclined impellers and radial impellers, which can meet the air volume and air pressure requirements under different working conditions. Its advantages are not only reflected in efficient wind pressure output, but also in smooth operation, low noise and convenient maintenance. Centrifugal fans are suitable for a variety of industries and environments, such as industrial exhaust, air conditioning systems, dust removal equipment, boiler air supply and ventilation and cooling. As a professional fan manufacturer, HAOBA focuses on the research and development and production of centrifugal fans, and continuously improves product performance and energy efficiency. Through advanced technology and strict quality control, HAOBA centrifugal fans achieve energy conservation and emission reduction while ensuring high air pressure and air volume, helping customers optimize the operating efficiency of ventilation systems.
