Description

Industrial Fan {INDUSTRIAL FAN}

The present invention relates to an industrial fan, and more particularly to a large industrial fan that can be installed for blowing in a factory or production site.

In general, fans that can perform comfort and drying functions by maintaining proper temperature by ventilation and blowing of indoor air are used for their purpose and purpose, from small products used in homes to large products used in barns, factories, or plastic houses. Various types are released depending on the principle of operation.

The fan is a device that generates wind by rotating the blades by the power of a motor. The fan is largely divided into household, office, industrial, agricultural, and the like, and its size, shape, and wind power vary depending on the place of use. It is being produced in a state.

In the case of a fan used for farming or industrial use such as a barn, a factory, or a plastic house, a large fan is usually used. The large fan circulates the air in the space through strong winds or lowers the temperature.

However, in the conventional large fan, only the large fan is installed in order to prevent the blind spots of blowing in a large space because the wings are driven only in place without rotating the left and right sides. Due to this, there was a problem that excessive fees and management costs are required to drive it.

In order to solve the above problems, the cost reduction effect is induced in the space where ventilation and ventilation are to be continuously performed, and the rotation radius of the large fan is wide and there is no heterogeneity close to the natural wind so that the blind area without the ventilation is not generated. A device for blowing air was required.
