Ventilation Controls for Dairy
From simple manual switches to thermostat controlled and fully automatic touchscreen interface, you can trust AutoVent to keep your livestock as comfortable as you are.
Curtain Motors (CMD & CMA Series)
DC vs. AC Choice
Choose 24V DC for safety around cattle and easier torque monitoring, or 240V AC for long runs up to 1,000 feet.
Mounting Options
We offer Wall-mount (W), Creeper (C), and Creeper & Cord-guide (G) configurations to fit any barn layout.
Key Feature
Electronic torque limits stop motors automatically if they jam, preventing ripped curtains.
Controller Comparison
From simple manual overrides to fully automatic touchscreen interfaces, these controllers manage the environment so operators can focus on their business.

| Livestock Focus | General livestock/dairy. | Designed specifically for calves and cows with "Cold Barn" defaults. |
Livestock Tips
Environmental controllers are essential for dairy and livestock. Ventilation dramatically impacts the health and production of the animals. Proper temperature, humidity, and ventilation are critical to the comfort and health of the animals.
Feedline Soakers
Don’t just cool the air—cool the cow. Our timed sprays use evaporation to drop body temperatures effectively without wetting udders.
Cold Barn vs. Warm Barn
Choose your philosophy. We provide settings for “Warm Barns” to prevent freezing or “Cold Barns” to prioritize fresh air and respiratory health.
Stop Curtain "Hunting"
Frequent, small movements kill motors. Our systems are designed to stabilize ventilation and extend equipment life.
The Smart Series
KVT-400
Take the guesswork out of ventilation with a high-definition touchscreen interface that manages your curtains based on real-time wind speed, direction, and temperature. It’s like having a dedicated manager for your barn’s climate, 24/7.
Captain
The Captain balances curtain and fan performance using integrated wind and temperature sensors. By automating these movements, you reduce energy waste and ensure a consistent environment that keeps your herd productive even as the weather shifts.
The Essentials
FanChief
Stop manually toggling switches. The FanChief monitors barn conditions to run your fans only when necessary, extending the life of your equipment and significantly lowering your monthly utility costs.
Serf C90
Designed specifically for compatibility with 90-volt curtain motors, the SERF C90 offers an easy-to-use interface for farmers who need dependable automation without unnecessary complexity.
Agriculture Duty VFD
Bring variable speed capabilities to any 3-phase project. This heavy-duty VFD allows you to ramp motor speeds up or down smoothly, preventing harsh starts and allowing for precise air-flow adjustments.
Manual & Hardware
Manual Controls
Our 24-volt manual curtain motor controls provide a rugged, reliable backup. Featuring heavy-duty toggle switches, these units are perfect for barns requiring direct operator control or emergency overrides.
Curtain Motors
Powerful, durable, and built for the barn environment. Our automated curtain motors provide the consistent torque needed to move large curtain systems smoothly, year after year.
Good to know
Proper environmental control is also essential for production. Heat stress in cows reduces milk production and lowers milk component levels. Similarly, poor ventilation can lead to respiratory problems in calves, which can make preventable lifetime performance losses.
