Chimney FAN is assembled just below the roof and it provides stable supply of fresh air to the interior of livestock building.

Especially in high cold weather, the air in livestock building  runs at a low speed. In order to avoid unnecessary airflow above the livestock and poultry, fans are installed on the roof to exhaust polluted air above the livestock and poultry gathering area in the house, which can effectively prevent harmful airflow from approaching the livestock and poultry in the building.
