Shanghai Blower Works Co., Ltd. is the first enterprise that has introduced the foreign technology in the fan field of the fan industry in China. Its fan technology comes from the German TLT-Turbo GmbH, the leader in the international fan market. Centrifugal Fans Shanghai Blower Works Co., Ltd. has a complete range of centrifugal fans, that is 84 models in total, with the maximum efficiency up to 90%, and it can provide the optimal fans for various cases, to achieve the goals such as low investment cost and low operation cost, high reliability, long service life, low noise, etc. The technical parameters of TLT-Turbo centrifugal fans are in a wide range, with maximum flow 6 million m3/h, maximum pressure 95,000 Pa, maximum temperature 700℃, and dust content up to 150g/Nm3. The parameters can cover the full range of industrial centrifugal fans; meanwhile, the method“to act according to actual conditions” is used, in other words, to obtain the type of fan whose parameters are totally matched as per modularization based on the parameters provided by the user, so that the fan operates in the range of peak efficiency, which avoids the limits that the domestic type series with mismatching parameters are forced together and that the pressure is higher but the structural strength fails to meet the requirement of linear speed. Axial-flow Fans The axial-flow fans of Shanghai Blower Works Co., Ltd. are the mature products supplied on the basis of a lot of actual operation experiences and after a great deal of aerodynamic model tests. The fans are designed in series, with standardized components and maximum efficiency up to 90%. The technical parameters of TLT-Turbo axial-flow fans FAF SAF PAF GAF RAF are in a wide range, with maximum flow 15 million m3/h, maximum pressure 20,000 Pa, and maximum temperature 300℃. In order to meet the demands of users as best as Shanghai Blower Works Co., Ltd. can, it has realized the fans with optimal technical & economical index.
