The core part of SSF jet fan is the technology of impeller. By referring to high technical level in the world and after continuous research and experiment, the series specifications and types meeting different demands are formed. They have the following characteristics:

(1) Blades of impeller have the characteristics of adjustable, light weight, corrosion resistance, high temperature resistance and non-breaking, which could ensure the service life of fans;

(2)  Cross section of blades is in wing shape, which has good aerodynamic shape and could ensure the performance of large pushing force of fans;

(3) Number and angle of blades could be changed according to the requirement to make the performance scope of fans be wide and meet demands of different users.

(4) New micropunch plate noise reduction structure is used, reaching the purpose of large sound absorption coefficient, wide sound absorption frequency band and effective reduction of noise.

(5) Direct air reversal can be conducted and air reversal efficiency is more than 65% of direct air, or could also reach more than 95% according to the requirements of users.

(6) Impeller, blades and motor can be removed separately, thus maintenance is convenient
