AutoVent’s livestock ventilation controls automate curtain and vent operation in dairy and livestock barns, keeping bedding drier and airflow more consistent than manual adjustment allows. Our Captain controllers use weather station data to open and close curtains automatically as conditions change.

This category covers the full barn lineup: Captain 10 and Captain 6 controllers, the CDS-0124 curtain door controller, CMC manual power-supply controls, and our CMA and CMD vent drive motors in light, medium, and heavy-duty configurations to match different curtain sizes and barn setups.

Frequently Asked Questions
How does automated curtain control help with barn bedding?
Automated systems open curtains more consistently than manual adjustment, which improves airflow and helps keep bedding, like sand bedding, drier over time.
What’s the difference between light, medium, and heavy-duty vent drive motors?
The CMA-115, CMA-180, and CMA-402 motors are rated for progressively larger loads. The right size depends on your curtain’s weight and length. Contact us if you’re unsure which fits your barn.
Can one controller run multiple curtains?
Some AutoVent controllers, like the CMC line, are built to manage multiple motors from a single control box. Check the specific model’s motor count or contact us to confirm it covers your number of curtains.
