BIDA Industrial Negative Pressure Fans
In the context of the vigorous development of modern ecological breeding, the scientific regulation of the environment in breeding farms has become the focus of the industry. Industrial negative pressure fans, as efficient ventilation equipment, are quietly emerging in ecological breeding farms, playing an irreplaceable key role and bringing significant economic benefits to the farms.
The working principle of industrial negative pressure fans
The working principle of industrial negative pressure fans is based on air convection and negative pressure ventilation. When the fan starts, the internal impeller rotates at a high speed, forming a strong low-pressure zone inside the breeding farm, similar to the negative pressure generated in the mouth when drinking with a straw. At this time, fresh air from the outside will be “dragged” into the room, forming an efficient air circulation. In a breeding farm, a negative pressure fan with a diameter of 1 meter can achieve an air exchange volume of 9,000 cubic meters per hour, which is equivalent to 2.5 cubic meters per second. This air exchange efficiency far exceeds that of natural ventilation, greatly increasing the speed of air renewal.
The application of industrial negative pressure fans in ecological farms
In ecological breeding farms, the application effect of industrial negative pressure fans is extremely significant. In summer, the breeding farm is hot and stuffy, and livestock and poultry are prone to stress reactions, which affect their growth and health. Negative pressure fans can quickly exhaust the hot air in the house and introduce cool air from the outside, effectively reducing the temperature inside the house. According to actual tests, when used with water curtains, the indoor temperature can be reduced by 4 – 15 degrees, creating a comfortable temperature environment for livestock and poultry. At the same time, the excrements of livestock and poultry in the breeding farm will produce a large amount of harmful gases such as ammonia and hydrogen sulfide, as well as dust. These pollutants not only have a pungent odor but also seriously endanger the health of livestock and poultry and increase the risk of disease transmission. Relying on its strong air extraction capacity, negative pressure fans can strongly exhaust these harmful gases and dust, significantly improving air quality. Professional tests have shown that after installing negative pressure fans, the ammonia concentration in breeding farms can be reduced by more than 50%, which greatly reduces the chance of bacterial growth and disease transmission, ensuring the healthy growth of livestock and poultry. In addition, in terms of humidity control, negative pressure fans keep the house dry by exhausting high – humidity air, further optimizing the breeding environment.
While creating a good environment for ecological breeding farms, industrial negative pressure fans also bring considerable economic benefits. From the perspective of equipment investment, compared with some complex air – conditioning cooling systems, negative pressure fans have a low investment cost, which is only about one – sixth of that of air conditioners with the same refrigeration capacity. In daily operation, their energy consumption advantage is even more prominent. Take the negative pressure fan of Guangzhou BIDA Industrial Equipment Co., Ltd. as an example, which adopts the patented “permanent magnet brushless motor system”. On average, a 1kW negative pressure fan can achieve the ventilation effect of a traditional 3kW fan. In a 1000㎡ factory building simulating the breeding farm environment test, BIDA negative pressure fan consumes only 0.8 yuan per hour, which is more than 60% more energy – efficient than ordinary fans. For large – scale breeding farms, the electricity cost saved over long – term operation is quite considerable. Moreover, because negative pressure fans improve the breeding environment, the incidence rate of livestock and poultry is reduced, the growth speed is accelerated, and the feed conversion rate is improved. Take pig farms as an example, after using negative pressure fans, the average daily gain of pigs can be increased by about 10%, and the slaughter time is shortened, thus increasing breeding income.
The future development of Industrial negative pressure fans
Industrial negative pressure fans have become a powerful assistant for ecological breeding farms to achieve efficient and green development. They protect the healthy growth of livestock and poultry by optimizing the breeding environment, while reducing breeding costs and improving economic benefits. With the continuous progress and innovation of technology, it is believed that industrial negative pressure fans will play a greater role in the field of ecological breeding, helping the industry move towards a more green and sustainable future.
