The Terrui 1830mm series is a powerhouse in large-scale climate control, engineered to outperform any standard Industrial Exhaust Fan in high-ceiling environments. Featuring a massive 72-inch blade diameter and a revolutionary double-layer polyethylene (PE) housing, this fan delivers a concentrated wind speed of 6.2m/s. It is the ultimate solution for thermal regulation in mega-dairy barns, sprawling poultry houses, and massive industrial warehouses where air stagnation is a risk.

Core Advantages

• Extreme Air Displacement: Moves volumes of air that far exceed standard Industrial Exhaust Fan units, covering a wider cooling radius with a high-velocity stream.
• Indestructible Housing: The double-layer PE frame is 100% corrosion-proof and UV-stabilized, making it immune to the rust and degradation that plague metal fans in humid farm environments.
• Direct-Drive Efficiency: Utilizing advanced motor technology, this fan eliminates the energy loss and frequent maintenance associated with belts and pulleys found in a traditional Industrial Exhaust Fan.
• Superior Wind Chill Effect: Reaches a core velocity of 6.2m/s, ensuring that the airflow effectively breaks the heat boundary layer around livestock or personnel for instant relief.

• 72-Inch (1830mm) Blade Sweep: Massive blade surface area designed to maximize cubic feet per minute (CFM) output.
• Heavy-Duty Double-Layer PE Frame: High-strength, hollow-molded construction provides both structural rigidity and superior sound dampening.
• Long-Distance Reach: Delivers a powerful, cooling breeze across distances exceeding 20 meters (65+ feet).
• Aerodynamic Bell-Mouth Shroud: A precision-contoured intake that reduces air turbulence, a design feature often missing in a low-cost Industrial Exhaust Fan.
• Maintenance-Free Design: Sealed bearings and a simplified drive system mean zero downtime and significantly lower operational costs over the product's lifespan.

When standard cooling isn't enough, the Terrui 1830mm fan offers a strategic upgrade over a typical Industrial Exhaust Fan setup.

1. Massive Coverage: A single 72" unit can replace up to four smaller fans, drastically reducing your electrical installation costs and total power load.
2. Unmatched Longevity: Designed for the harshest agricultural settings; our PE housing is built to last 20+ years without cracking or corroding.
3. High-Velocity Performance: While many Industrial Exhaust Fan models focus only on air exchange, this unit focuses on active cooling through high wind speed.
4. Quiet Power: Despite its size, the aerodynamic optimization ensures that noise levels remain low, protecting animal welfare and productivity.

A: A standard exhaust fan is designed to pull air out of a building. This 1830mm fan is designed to circulate air at high speeds internally, which is significantly more effective at cooling animals and workers in large, open-door structures.

A: Yes. The double-layer hollow construction acts as a shock absorber, making it much more resilient to physical impacts than traditional thin-gauge metal or fiberglass shrouds.

A: Extremely. By using a direct-drive motor and large-diameter blades, it achieves a higher CFM-to-Watt ratio than most smaller Industrial Exhaust Fan configurations, saving you up to 30% on energy costs.
