Product Description
With the development of society, the application of fans is becoming more and more extensive, and the aquaculture industry has also used fans. The transmission of livestock fans has undergone dynamic and static balance verification. When not in operation, strong springs can tightly close the shutters. Each fan has passed a separate quality inspection. The casing and shroud are made of strong, coated copper plywood. The shutters are made of coated steel. The plywood is made to ensure the strength. The intermediate wheel and sash belt are made of aluminum die-casting and are equipped with reinforcing ribs to increase the service life. So, how to choose a livestock breeding fan suitable for your own pasture? Below, We will analyze it in detail for you.
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 anticorrosive 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.

For decades, the "slant wall" fan was the preferred poultry house exhaust fan. Testing found that by simply moving a traditional exterior panel shutter to the intake side of the fan, the air-moving capacity of the fan was increased five to ten percent.
Furthermore, the interior fan shutter location resulted in a reduction in dust collection as well as making it easier to clean than a shutter mounted on the exhaust side of a fan. The slightly slanted fan housing protected the fan motor and components from the rain as well as facilitating the draining of any moisture that collected in the bottom of the fan housing. For decades, tens of thousands of slant wall fans were installed in tunnel-ventilated houses and little if any problems were reported.
The only aspect of the slant wall fan that producers occasionally took issue with was the shutter. Though it was easier to clean than one mounted on the exterior of the fan, it still required frequent cleaning when the fan was being used for tunnel ventilation during hot weather. Furthermore, when being cleaned the shutter blades were often damaged or bent which resulted in the fan shutter not fully closing when the fan was not in use. In partial response to these concerns the "butterfly" shutter, also referred to as a "damper door," fan was developed. A butterfly shutter typically consists of two large semi-circular pieces of galvanized sheet metal installed on the exhaust side of a fan.
The two shutter blades are connected to the fan housing with a vertical hinge and pulled closed through the use of a spring. When fully opened, the two large shutter blades offer minimal resistance to air flow which results in a small increase in the air-moving capacity of a fan when compared to the same fan equipped with a interior shutter.
Most importantly, the vertical installation of the shutter blades means that when dust collects on the shutter blades, the additional weight does not affect the opening of the shutter as it does with fans with horizontal shutters blades. Since the accumulation of dust on the butterfly shutter blades does not adversely affect the air-moving capacity of a tunnel fan, producers are ensured that the maximum air-moving capacity of their fans, and therefore bird cooling, will be maintained over the course of a summer with little or no fan maintenance required.
Since the exterior butterfly shutters protect the fan motor and components from the rain and the shutters are mounted vertically, the slanted/tilted housing is not required. Due to the improved performance of fans with butterfly shutters and the fact that they are very easy to maintain they have replaced the traditional slant wall fan as the preferred style of exhaust fan for poultry houses. But, butterfly shutter fans are not without issues.
One of the most significant underappreciated advantages of a traditional slant wall fan over a butterfly shutter fan is that most of the fan and its components are essentially installed outside the house. The only component that is constantly exposed to the environment within poultry house is the aluminum or plastic fan shutter; the remainder of the components are only exposed to poultry house air when the fan is operating.
