Chimney Air Exhaust

HAILAN Exhaust Air Chimney Feature and advantages：

1.Chimney fan series products are specially designed and developed for the strict ventilation requirements of closed livestock and poultry houses. In alpine or temperate climate areas, the air in livestock and poultry houses runs at low speed, so special attention should be paid to the change of wind speed to avoid unnecessary airflow over livestock and poultry.  The fan installed on the roof can discharge the dirty air above the livestock and poultry gathering area in the house, effectively avoid harmful airflow near the livestock and poultry.  

2.Applying the principle of hot air rising, The dirty hot air can be discharged from the house through the exhaust air chimney on the top of the building  , the fresh cold air outside the house is inhaled, form a vertical ventilation mode, the crosswise airflow does not cross each other to reduce the incidence of livestock and poultry disease.  

3. It can also be used as a backup ventilation system during power outages.  In case of power failure, the air valve and air inlet of the fan can be opened under the action of spring self-reset or standby power supply, and the chimney effect can be used to form natural ventilation and prevent asphyxiation of livestock and poultry.
