Russia has rich land reserves and vast pastures, including more than 2.5 million hectares of sown area and 4 million hectares of pasture and hay area, which can breed poultry, dairy cows and beef cattle. The developed arable land area is about 0.126 billion hectares and the pasture area is 72.6 million hectares. Russia has a very good foundation for animal husbandry. Russia is also a big grain exporter in the world, with diverse and sufficient feed materials, It has good conditions for the development of animal husbandry.

     1, the farm environment is relatively dirty, good ventilation and cooling is related to the growth and development of livestock, production of milk.
2. Traditional high-speed fans are usually only installed on the top of the feed channel and exhaust outlet, with limited coverage, high noise and strong airflow.
 

1. The small fan originally used in the dairy farm cannot effectively improve the farm environment. The large fan of the king ventilation industry has a stable torque of 260N · m and a full load air volume of up to 17676 m3/min, which is more significant than the traditional small fan.
     2. A 17676 m3/min king ventilation super-large fan covers an area of more than 2400m2, and the large air volume blows to all parts of the dairy farm without dead corners, thus inhibiting the growth of germs, forming a comfortable and refreshing breeding environment, and improving the milk yield of dairy cows.

3. The average power consumption of the king ventilation super-large fan is less than 1 degree per hour, which reduces the expenditure for relevant personnel.
