Product description
Shipping & Return
1. Premium Anti-Rust Material Construction
This butterfly door exhaust fan adopts 275g hot-dip galvanized steel housing and 1.2mm thick stainless steel blades. The thickened metal structure provides outstanding anti-corrosion and anti-rust performance, adapting perfectly to high-humidity, ammonia-filled poultry house environments for long service life.
 |  |
2. Automatic Butterfly Shutter Design
Equipped with linkage butterfly doors, the shutters fully open synchronously when the fan starts to reduce wind resistance and boost airflow. Once the fan shuts down, the doors close tightly automatically, effectively blocking dust, debris and foreign objects from entering the fan to protect internal components.
 |  |
3. Stable Negative Pressure Ventilation
Optimized for tunnel ventilation systems, the fan creates strong even airflow to exhaust heat, moisture and ammonia inside chicken houses. With low-vibration operation, it supports 24-hour continuous running, a reliable ventilation solution for commercial layer and broiler farms.
