Dongguan Jiafeng livestock fan.

Because livestock fans are used in the pig industry, such as pig, chicken, cattle and other animal husbandry industries, they are called breeding fans and livestock fans. In fact, they are also called negative pressure fans.

The better brands in the industry generally include: Nanmu, Jiafeng, Detong, Damuren, etc.

Negative pressure fans are mainly used in two major industries: industry and animal husbandry. The principles are the same. There are two types: galvanized sheet square and fiberglass trumpet shaped.

Galvanized sheets are lighter, smaller and easier to install, and are often used in industry. FRP trumpet-shaped sheets are corrosion-resistant and more suitable for the breeding industry, because ammonia in the house is corrosive, and Fiberglass material is corrosion-resistant.
