How many blades are good for HVLS industrial fans?
The HVIST fan was invented by a joint venture between a US and a Chinese company in 1999. After almost 20 years of development, various industrial fans with different numbers of blades have emerged. Currently, domestically and internationally, industrial fans mainly come in three-blade, four-blade, five-blade, six-blade, and eight-blade configurations. In theory, the more blades a fan has, the greater the airflow. However, since industrial fans are generally larger in size, more blades also mean more weight and increased safety risks. Therefore, it is necessary to strike a good balance between airflow and quality. Currently, industrial fans with five or six blades are most popular on the market. These two types are also the main products promoted abroad and have been market-certified for over a decade. As long as manufacturers strictly require high quality and safety for the blades, they can meet market demand.
Large fans in the indoor basketball hall improve ventilation and cooling
With the promotion of nationwide fitness, various communities have built indoor basketball courts of different sizes. However, the large span, high height, and relatively sealed building structure of basketball courts pose great challenges to ventilation and cooling. In recent years, many venue constructors have found that large fans (big ceiling fans) can perfectly solve the ventilation and cooling problems, which are tricky for indoor basketball courts.
Principles to be followed in designing industrial large fan blades
Industrial large fans have been imported into China from abroad, and batches of industrial fan manufacturers have been continuously researching, developing, and producing a full range of large industrial fan series products suitable for various environmental improvements in China. High-quality large fans are often built on good materials and unique advanced designs. The fan blades of industrial large fans are made of 5052 aviation aluminum, and unique blade designs can maximize the advantages of large fans and meet the needs of different users. When designing fan blades, industrial fan manufacturers need to follow certain principles.
