Heat Stress

Dairy cow production and health are greatly affected by heat stress from lack of airflow.

Poor Ventilation

Mold and disease risk increase due to stagnant air, humidity, and poor ventilation. 

Pest Issues

Pests annoy dairy cows when there is a lack of air circulation. 

Temperatures & Gases

Inconsistent airflow leads to uneven temperatures, jeopardizing dairy cow health.

Invented by MacroAir for Dairy Cows.

MacroAir's founder, Walter Boyd, invented HVLS fans to help cool dairy cows and increase production.

We are rooted in making cattle comfortable and continue our commitment to creating happy cows.
