Characteristics and introduction of livestock fan

The animal husbandry fan, also known as the negative pressure fan, is a new type of ventilation fan and belongs to the axial flow fan. It is mainly used in the negative pressure type ventilation cooling project and is called a negative pressure fan. The negative pressure ventilation cooling project includes the meaning of ventilation and cooling, and the ventilation and cooling problems are simultaneously solved. The negative pressure fan is also used in the fields of positive pressure type curtain electric air conditioning, positive pressure air supply, positive pressure air blowing and the like. The negative pressure fan has the characteristics of large volume, large air duct, large wind blade diameter, large exhaust air volume, ultra low energy consumption, low speed and low noise. The negative pressure fan is mainly divided into a galvanized square negative pressure fan and a FRP horn negative pressure fan from the structural material. The structure and technical parameters of all the galvanized square square negative pressure fans on the market are basically the same, and the classification of the negative pressure fan models will be described in detail. FRP horn-shaped negative pressure fans are divided into belt type and straight type according to different transmission modes, and the classification of negative pressure fan models will be described in detail.
