What is the role of Negative Pressure Fan in greenhouse industrial farming?

1. Improve air quality
Negative pressure fans create a negative pressure environment to vent indoor dirty air and harmful gases to the outside while introducing fresh air. This ventilation method can effectively reduce the concentration of harmful gases such as ammonia, carbon dioxide and carbon monoxide, thereby improving the breeding environment and promoting the healthy growth of animals. In addition, negative pressure fans can also reduce the spread of pathogens in the air and reduce the incidence of diseases.

2. Improve ventilation efficiency
Negative pressure fans use mechanical kinetic energy to exhaust air from greenhouses or farms, quickly replacing stagnant air, thereby improving ventilation efficiency. This efficient air circulation helps maintain suitable temperature and humidity conditions and ensure the stability of the breeding environment.

3. Energy saving and consumption reduction
Negative pressure fans are more energy-efficient than traditional positive pressure ventilation systems when in operation because they do not require additional power to push air in, but instead achieve air exchange through natural convection. This energy-saving feature not only reduces operating costs, but also conforms to the global trend of energy conservation and emission reduction.

4. Promote animal health
Negative pressure fans improve the respiratory health of animals by improving air quality and reducing heat stress and air pollution. Studies have shown that animals in farms using negative pressure fans grow faster, have higher reproduction rates, and have lower morbidity rates.

5. Reduced energy consumption
Negative pressure fans consume less electricity during operation and can also reduce the energy consumption of the cooling system. For example, in pig houses, negative pressure fans can significantly reduce cooling costs when used in combination with wet curtains.

6. Automation and intelligent management
Modern negative pressure fan systems are usually equipped with intelligent sensors and control systems that can automatically adjust wind speed and ventilation volume according to environmental parameters to achieve precise environmental control. This intelligent management not only improves production efficiency, but also reduces labor costs.

7. Economic benefits
Negative pressure fan systems have a long service life, low maintenance costs, and can significantly improve farming benefits. For example, in animal husbandry, the use of negative pressure fans can reduce the use of antibiotics and reduce medical costs
