Eliminate Heat Stress.
Protect Milk Yield.
Heat stress begins at just 25°C. Our commercial-grade 4-blade and 6-blade fans deliver the critical 2.5m/s wind speed required to cool cow core temperatures, actively preventing the typical 15% summer drop in milk production.
Why Commercial Dairies Choose NexAgri Fans
Poor air quality and heat are hidden profit killers. We engineer the exact environmental parameters required to maximize herd potential.
Targeted Velocity
Concentrates high-speed airflow directly at cow level to break the thermal boundary layer around the hide, actively cooling core body temperatures.
Ammonia Evacuation
Constant, high-volume air exchange flushes out harmful gases and evaporates alley moisture, drastically reducing the risk of respiratory issues and digital dermatitis.
Yield Protection
By keeping cows comfortable in high heat and humidity, Dry Matter Intake (DMI) remains stable, preventing devastating summer milk production slumps.
Strategic Ventilation Configurations
Choosing the right blade count is the difference between simple air movement and scientific cooling.
4-Blade High-Velocity Fan
Focused Punch
Engineered to concentrate airflow and achieve necessary 2.5m/s wind speeds at longer throws. The lighter blade assembly is highly cost-effective and perfect for forcing air through narrow alleys and deep bedded areas.
6-Blade Industrial Fan
Maximum Volume (CFM)
Moves massive volumes of air to ensure rapid total air exchange in wide-span barns. Optimized for low-RPM stability and creating broad, uniform air columns across head-to-head stalls.
Engineering Deep Dive
Built for 24/7 commercial dairy performance in corrosive, high-dust environments.
Total Cost of Ownership (TCO) & Planning Guide
Ventilation is an active asset. Proper placement and automation controls dictate both your electrical costs and your yield recovery.
1. Strategic Placement & Spacing
Airflow is not infinite. To maintain the minimum required 2.0 to 2.5 m/s velocity across the barn, fans must be staged strategically. Over-spacing leaves "dead zones" where heat and ammonia accumulate.
Our engineering team utilizes fluid dynamics principles to calculate exact pitch angles and longitudinal spacing based on your barn's truss height and layout, ensuring end-to-end coverage.
2. THI Automation & Energy Savings (OpEx)
Running fans at 100% capacity year-round wastes massive amounts of electricity. Our systems are designed to integrate seamlessly with Variable Frequency Drives (VFDs) and smart THI (Temperature-Humidity Index) sensors.
As barn temperatures drop at night, the fans automatically throttle down. Combined with our IE3 premium efficiency motors, this smart regulation drastically cuts electrical OpEx.
3. Milk Yield & DMI Protection
When core temperatures rise above comfortable limits, cows exhibit depressed Dry Matter Intake (DMI) and spend energy panting instead of producing milk. Proper velocity cooling restores normal feeding behavior, helping minimize significant summer milk production losses caused by heat stress.
