How many blades are good for HVLS industrial fans?

Large industrial fan inverter as the main control system, the need for regular inspection and maintenance, especially in the summer continuous use of the fan is good, need to be checked once every two weeks, in order to prevent the inverter failure to cause the fan can not be used normally.

As a large air volume and low speed fan, the industrial large fan effectively solves the problems of high temperature and stuffiness in the tall building space, exhaust gas dust, humidity and high energy consumption.It has made a difference for car manufacturers.

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.
