The greenhouse maintains a delicate balance between light, heat and humidity. Without proper ventilation, plants are exposed to stress, mold growth, and stunting. Therefore, choose the right exhaust fan to consider not only the power, but also whether its performance is in line with your environment.

For greenhouses of all sizes, theCircular exhaust fanAll provide unique and effective solutions for stable and energy-efficient airflow. In this guide, Aosair will explain why round exhaust fans are the first choice for agricultural applications.

GreenhousesExhaust fanThe function

Plants need air circulation just as they need water and sunlight. Without air circulation, heat builds up inside the plant, humidity rises, and photosynthesis slows. A well-ventilated greenhouse can:

• Preventing heat stress on crops

• Decrease in fungal diseases

• Controlling condensation

• Maintaining CO2 exchange

• Improving pollination and growth cycles

At this point, a strong and efficient exhaust system becomes critical.

WhyCircular exhaust fanMore suitable for greenhouses

1. Uniform airflow distribution

The circular blade design ensures even airflow over a large area. Circular fans reduce corner dead spots compared to square or directional fans.

2. Easier wall hanging

Most greenhouses use polycarbonate or polyvinyl chloride wall panels. The circular fan can form a neat fit, making sealing and insulation around the bracket easier.

3. Compact housing, high CFM

Aosair's circular fans have high output while maintaining a low profile design, making them ideal for tight or modular greenhouse structures.

4. Natural beauty

Circular fans can be seamlessly incorporated into greenhouse layouts, particularly in circular vents or roof dome designs.

5. Energy efficiency

Optimized for all-weather operation in warmer climates, our fans help you reduce your power consumption without compromising airflow.
