Ventilation

Optimize Airflow, Reduce Heat Stress, and Improve Animal Health

Proper barn ventilation is essential for maintaining a healthy environment for your livestock and maximizing productivity. At KBS, we specialize in the design, installation, and servicing of complete ventilation systems for dairy barns, beef operations, and agricultural buildings.

Whether you need to retrofit an existing barn or are planning a new build, our expert team offers efficient, reliable solutions using high quality equipment from industry leading vendors.

Custom Barn Ventilation System Design

We offer custom ventilation design services tailored to your barn’s structure, regional climate, and herd size. Our goal is to improve:

  • Airflow and air exchange
  • Ammonia and moisture removal
  • Temperature regulation
  • Cow comfort and production performance

Our systems combine natural and mechanical ventilation options to keep your barn cool in the summer and dry in the winter.

Our Barn Ventilation Equipment

We carry a full lineup of high-performance barn ventilation products that are built to last in demanding farm environments.

Sidewall Curtains for Natural Ventilation

Sidewall curtains allow you to take advantage of fresh air while protecting livestock from wind, rain, and cold. At KBS, we fabricate custom-made curtains in-house, allowing quick turn-around times.

Features:

  • Manual or automated curtain systems
  • Weather-resistant materials
  • Custom sizes for any barn layout

Curtain Doors & Air Curtain Doors

Curtain doors provide wide, convenient openings for tractors and equipment, while air curtain doors create a barrier of airflow to maintain climate control and reduce insect and dust intrusion.

Benefits:

  • Energy efficiency
  • Easy access
  • Improved cleanliness and climate stability

Air Curtains for Climate and Pest Control

Install air curtains in high-traffic barn entryways to keep conditioned air inside and block insects and airborne contaminants from entering.

Advantages:

  • Reduce heat loss
  • Enhance hygiene
  • Maintain consistent temperatures year-round

Power-Vented Barn Ventilation Systems | Cross-Ventilation & Tunnel Airflow Solutions

Upgrade from basic barn fans to fully engineered power-vented ventilation systems designed to improve air quality, control temperature, and enhance livestock comfort. These systems are ideal for dairy barns, beef barns, freestall barns, and other agricultural buildings where consistent airflow is critical.

Our systems combine cross-ventilation, tunnel ventilation, and automated fan controls to move large volumes of air efficiently through the barn—improving animal health and reducing energy costs.

Power-Vented Barn Ventilation Features:

  • High-performance exhaust and circulation fans
  • Cross-ventilation systems for uniform airflow across the barn
  • Tunnel ventilation systems for maximum air exchange
  • Variable-speed, sensor-controlled fans for energy savings
  • Automated climate control for precise temperature and humidity regulation

Benefits of Power-Vented Ventilation:

  • Improves airflow and air exchange
  • Reduces ammonia, moisture, and airborne contaminants
  • Lowers heat stress for higher milk production and healthier livestock
  • Cuts energy use with smart fan operation and system zoning
  • Suitable for retrofit or new barn construction

We design every ventilation system for barns to match your facility’s layout, regional climate, and herd size—ensuring year-round performance and durability.
