Ventilation and Cooling Fans

Eliminating Productivity Loss!

Why Do We Need Fans?

During hot weather, cattle experience heat stress, leading to significant losses in:

Milk production
Reproductive performance
Meat yield

Weakened immune systems also compromise animal health. Research shows cows suffering summer heat stress continue underperforming through the following winter.
Proper ventilation and misting systems aim to prevent cattle body temperatures from exceeding critical levels.

Why Choose TETA Ventilation and Cooling Fans?

Cattle require substantially more airflow than humans - a single lactating cow needs ventilation equivalent to 40 people. Barn air should refresh 6-8 times hourly, making fans essential.
Effective cooling requires:
1. Complete wetting of animals
2. Drying with 2.8-3.0 m/s air velocity

Random fan selections fail to achieve desired results. Key specifications to evaluate:

Air velocity at distance
Airflow volume (m³/hr)
