In recent years, due to the limitation of land use in China, it has been difficult to obtain government's approval to apply new land or expand land for husbandry breeding. Therefore, animal breeding farmers began to focus on multi-floor farming. Use less land to achieve intensive and large-scale animal breeding so as to increase land using efficiency.
In order to adapt to this breeding mode, we developed the HPF series high negative pressure fan, which can carry -200Pa high negative pressure with long term and stable operation.
This year, the HPF series of high negative pressure fans have been installed and used in multi-floor pig houses.
