The SYDF-II centrifugal fan is independently developed based on user needs, making it more practical and providing users with more choices. This series of products not only has a higher flow rate and pressure than similar products, but also overcomes the disadvantages of multi wing fans in dust and oil fume removal that are difficult to clean. The fan structure is divided into two types: A and B. The A model is in the shape of a snail shell, while the B model is square. The snail shell is lightweight and suitable for ventilation and air exchange in general situations; Square has good stability, easy installation, and is suitable for kitchen oil fume exhaust.
