Providing fresh air in areas within the Dairy/Calf/Beef barns can be crucial to the well being of the animals. Specifically in calf barns, where the top two concerns are ventilation and respiratory disease. A fan pulls fresh air from the outside of the building and pushes the air through the ventilation tube and throughout the barn. The system will provide fresh air to the animals. The Positive Pressure Ventilation Tube is a self-contained system; therefore, it does not allow pathogens to enter into the system and be dispersed to other animals in the barn. The ventilation tubes can provide low distribution of air in the cold weather without causing a draft and a higher distribution of air in warmer weather.
