Looking for the welfare of the animals that live in industrial farms and its workers, it is necessary to maintain a high air quality and installing a good ventilation is enough.
Avoiding bad odors and achieving a healthier air in the animal exploitation farms will lead to a better productivity both of the labor and of the animals that are in the farm for their growth (pigs fattening) or production (laying hens).
The carbon dioxide, hydrogen sulfide, ammonia and water vapor that get concentrated in the farms are a danger to the health of the animals. Also the own facilities and machinery can be harmed. So it is vitally important to extract these gases and constantly renew the air of the farm.
One of the most recommended options is the so-called under pressure ventilation, consisting of a natural air intake from the outside in one of the walls (opening with grid) and a mechanical extraction (one or several fans) in the opposite wall or roof, can be controlled by a variator to adapt ventilation to the needs of the farm and animals according to the time of year.
Another application in farms that requires the use of fans, mainly in poultry farms, is the cleaning of eggs by air. An MA of Casals, made of aluminum, perfectly resists the corrosive environment of this application since the droppings of the birds are highly corrosive. The function of the fan will be to separate these droppings from the egg thanks to the supply of clean air at high speed.
