400mm Industrial Exhaust Fan: The Dual-Purpose Solution for Fire Safety and Livestock Cooling

The Terrui 400mm series represents a breakthrough in versatile airflow engineering. While primarily rated for high-efficiency fire smoke exhaust, its robust design makes it an essential component for modern livestock ventilation systems. Measuring 400x400mm, this compact powerhouse is designed to rapidly clear harmful gases, heat, and smoke, ensuring a safe and breathable environment for both industrial facilities and high-density animal housing.

• Acoustic Comfort: Engineered with advanced noise-reduction technology to operate at ≤70dB, protecting animal welfare and worker hearing
• Dual-Function Utility: Seamlessly transitions from a daily-use livestock ventilation unit to a high-capacity emergency smoke extractor
• Corrosion Resistance: Features a specialized protective coating that prevents rust even when exposed to the high ammonia levels of poultry and dairy barns
• Space-Saving Design: The 400mm square frame allows for easy installation in wall headers or integrated ductwork where space is at a premium

• Precision-Balanced Blades: High-grade steel blades are single-riveted to ensure vibration-free rotation and a steady, concentrated airflow
• Industrial-Grade Motor: Equipped with a high-torque motor designed for continuous operation (24/7) without the risk of overheating
• Enhanced Safety Grills: Heavy-duty wire mesh on both sides prevents debris entry and protects personnel/livestock from moving parts
• High-Speed Air Exchange: Capable of high-velocity air displacement, a critical feature for effective livestock ventilation in humid or dusty environments

1. Multi-Industry Compliance: Meets rigorous fire safety standards while fulfilling the ventilation requirements of modern agriculture
2. Animal Productivity: By maintaining a quiet 70dB environment, these fans reduce the noise-induced stress that typically lowers egg and milk production
3. Low Operational Costs: The energy-efficient motor design ensures that your monthly utility bills remain manageable even during peak summer usage
4. Long-Term Reliability: Built to last in harsh conditions, reducing the frequency of equipment replacement and maintenance downtime
