Shandong Jianyu Heavy Industry's series of silent rotary blowers have been put on the market. By optimizing the gear meshing clearance and installing mufflers, the operating noise is reduced to as low as 65dB. Specifically designed for aquatic seedling farms, this model has an air volume adjustment range of 0.5-20m³/min. After being applied in seedling farms in Qingdao, Yantai and other places, the survival rate of fry has increased by 8%.
