Polyurethane chimney fan

The chimney fan series products are specifically designed and developed to meet the stringent ventilation requirements of enclosed livestock and poultry houses. In high-altitude areas or regions with temperate climates, where the air flow rate inside livestock and poultry houses is relatively low, special attention should be paid to changes in wind speed to avoid unnecessary air currents above the livestock and poultry. They can meet the demand for air volume in different seasons and be applied to various types of livestock and poultry houses, with advantages in the following scenarios: being used in extremely cold regions; when there is no ceiling-mounted air inlet in the livestock and poultry house; and in constant-pressure or low-pressure ventilation modes.
Chimney exhaust fan: Utilizing the principle that hot air rises, polluted hot air can be discharged from the upper part of the livestock and poultry house through the exhaust outlet, while fresh cold air from outside is drawn in, forming a vertical ventilation mode. The air flows do not cross each other, thereby reducing the risk of diseases in livestock and poultry.
Chimney inlet fan: Installed on the roof, it uses a high-pressure, high-flow fan to provide stable fresh air for the building. It mixes with the hot air above the roof at the inlet, and the mixed air flow is dispersed around the animals in the building through guide plates, which is both energy-efficient and avoids the risk of direct cold air blowing out.
