Great Effect on Ventilation, Dehumidification, and Cooling
The humid and hot air usually is in the roof of the greenhouse. It is hard to take them out of the greenhouse with current vent way, so it may cause the growth of bacteria and germs, and bring the disease to the plant. The Easy wind fan may solve this problem well.


Rainproof Patent Design, Good Sealing Performance

The material of the fan is similar to the film, so there is no chemical reaction at the touch area between the fan and film. Due to the same thermal expansion, the fan will not leak the rain. (when the fan is installed on PC greenhouse and glasshouse, it can be sealed with the glass glue). When opening the fan, the cap will be opened by the wind to keep the ventilation, when the fan is closed, the cap will drop automatically due to gravity (can be used within 45 degree of the horizontal angle). The cap is covered tightly with the barrel after the fan is closed. It can prevent heat loss, prevent the air, rain, and snow outdoor to enter the greenhouse and guarantee the sealing and safety.

Anti-aging, Durable
The material is pure PE material, adding anti-aging agent, improve the anti-aging effect.
