Natural ventilation

Natural ventilation optimizes productivity

Good ventilation is very important to keep fresh air circulating in buildings housing your animals – whether calf shelters or barns for dairy cows. Cows need fresh clean air to achieve their production potential. Unventilated or poorly ventilated structures with high levels of moisture, manure gases, pathogens and dust, and poor temperature control, provide an adverse environment for animals. Well planned natural ventilation in barns helps keep your animals comfortable – and productive.

Control natural air movement

DeLaval curtains, ventilation panels and chimneys offer you flexible control of natural air movement to provide the well-ventilated conditions your cows need for year round good health and productivity. Choosing the right ventilation solutions will help you to create a good working environment, no matter what kind of barn you have. The curtains and ventilation panels all offer the option of manual or automatic control.
