1. Select the type according to the composition of the exhaust gas: the composition of the exhaust gas in the environment
determines the type of livestock fan. There are currently two main types of materials used on the market for fans. One is a
negative pressure fan made of FRP anti-corrosive material, and the other is a negative pressure fan made of galvanized sheet material, if the exhaust gas is exhausted. The body composition contains acid and alkali corrosiveness, so the livestock breeding fan made of FRP anticorrosive material should be selected. If the exhaust temperature is not high and non-corrosive, a negative pressure fan made of galvanized metal sheet can be used.
2. Select the size according to the installation position: The installation position of the fan determines its size, the exhaust
capacity and power of a single fan, and the size of the negative pressure fan should be selected as much as possible. If the installation location is large and the negative pressure fan selected is small, the exhaust effect will definitely not be good. It is difficult to seal the rainwater leakage. If the size of the livestock fan is larger than the size of the installation location,it cannot be installed.
3. Choose the type of fan according to economic capacity: The cost of FRP anticorrosive negative pressure fan is higher than galvanized steel negative pressure fan. If there is sufficient investment budget, use FRP anticorrosive negative pressure fan.
After all, FRP negative pressure fans are more durable than galvanized sheet negative pressure fans. If the current funding is insufficient, choose a galvanized sheet negative pressure fan.
