Product Description
Our butterfly cone exhaust fan is a high‑static negative pressure ventilation solution designed for commercial poultry tunnel houses. It is engineered to deliver reliable air exchange, stable negative pressure and efficient climate control for large‑scale broiler farms, layer houses and livestock barns.
 |
The fan adopts a cone‑shaped airflow design with butterfly double‑door structure. When the fan stops, the double doors close tightly with full rubber sealing, effectively preventing backdraft, cold air infiltration and light leakage into the poultry house. This sealing performance helps reduce temperature fluctuation, improves barn environment stability and supports consistent poultry growth conditions.
With heavy‑duty construction, the fan housing can be made of fiberglass or galvanized steel, offering good corrosion resistance against humid, dusty and aggressive farm environments. The integrated fan unit includes fan blade, motor, cone frame, protective mesh and butterfly door assembly, making it suitable for tunnel ventilation systems that require long‑term continuous operation.
This poultry cone exhaust fan is widely used in automated chicken houses, commercial layer farms, broiler houses and pig barn ventilation projects. It helps farmers improve air quality, control indoor temperature, reduce ammonia accumulation and create a healthier growing environment for livestock and poultry.
