Ventilation for poultry houses
Animal welfare and productivity in poultry farming
Ventilation is an essential element for keeping poultry houses healthy and productive. Evel’s HVLS and axial fans are designed to create an ideal microclimate in poultry farming facilities, reducing animal stress and improving growing conditions.

Fresh air at all times, less ammonia and better performance: the role of ventilation in poultry houses
In chicken and hen farms, poor air quality quickly leads to the buildup of ammonia, high humidity, unpleasant odours and the spread of pathogens. An uncontrolled microclimate increases stress in animals, slows growth and negatively affects the quality of eggs and meat.
The Evel solution: HVLS and axial fans for poultry houses
Evel’s HVLS and axial fans ensure continuous and uniform air circulation inside poultry houses. By moving large volumes of air at low speed, they promote constant air exchange and the removal of excess ammonia and humidity.
The result is a healthier environment with uniform temperatures and an ideal climate for chicken growth and the well-being of laying hens, all with minimal energy consumption and without creating uncomfortable drafts for the animals.
