Heat stress is a growing challenge for dairy farmers worldwide. Rising temperatures in combination with high humidity can significantly impact cow health and productivity, leading to lower milk yields, reduced fertility rates, and increased health risks. Effective cow cooling is no longer a luxury—it’s a necessity.

That’s why Vostermans Ventilation has developed the Multifan AirBreeze—a solution designed to improve cow comfort even during the hottest days.

Optimal airflow

The Multifan AirBreeze helps farmers maintain a stable and healthy barn climate, ensuring cows stay cool and productive. By generating consistent airflow at a minimum speed of 2 m/s at cow level, it reduces heat stress, encourages feed intake, and supports milk production, even in extreme heat.

Available in two versions, farmers can choose the best fit for their barn setup:

• Maximized cooling reach: Ideal for larger barns, moving air across 18 x 5 meters for effective heat stress relief with fewer fans.
• Energy efficiency: A highly efficient solution that optimizes airflow while keeping power consumption low.

A long-term investment in dairy farm success

A comfortable barn climate is essential for healthy, productive cows. The Multifan AirBreeze is specifically designed with the cow’s needs as the starting point. Built with durability and reliability in mind, designed to withstand dust, moisture, and fluctuating temperatures—delivering long-term performance with minimal maintenance.

For farmers looking to protect their herd’s well-being and ensure consistent milk production, effective air circulation is key.

The real impact of heat stress

When cows struggle to regulate their body temperature, their feed intake drops, their respiration rates increase, and milk production suffers. The stress of overheating also raises the risk of infections, hoof problems, and fertility issues, affecting long-term herd health and farm profitability.

Without an effective cooling strategy, the consequences can be felt throughout the entire operation—from reduced output to additional veterinary costs.

Beyond summer: year-round climate control

Ventilation matters all year round. In winter, poor air circulation can lead to death spots, condensation issues, damp bedding, and respiratory problems. The ECplus and Vplus technology allow fans to run at lower speeds in cold conditions, preventing moisture buildup while saving energy.
