Ventilation principle of animal husbandry fan

The air discharged from the fan makes the indoor air pressure drop and the indoor air becomes thinner. The characteristics of the animal husbandry fan form a negative pressure area, and the air flows into the room due to the compensation of air pressure difference. In the practical application of industrial workshop, the animal husbandry fan is concentrated on one side of the plant, and the air inlet is on the other side of the workshop room. The air is convective from the air inlet to the animal husbandry fan. During this process, the doors and windows near the livestock fan remain closed. The main structure of animal husbandry fan is mainly composed of wind blade, motor, outer frame, protective net, support frame, louver and other parts. The motor drives the wind blade to produce air flow, which can achieve the air collection effect. The aluminum alloy wheel hub of aviation is light in weight, high in strength, good in toughness and not broken. The main structure of animal husbandry fan is composed of wind blade, motor, outer frame, protective net, support frame, shutter and other components. The motor drives the wind blade to produce air flow and move 100% The type of leaf window can be equipped according to the user's needs. The shutter can be opened automatically after starting up and closed automatically when it is stopped, so as to reduce the entry of outdoor dust and foreign matters, and also reduce the impact of rain, snow and wind.
