FRP negative pressure fan is a common ventilation tool in animal husbandry, but also used in other industries, here to share its own characteristics. 

1. The equipment will last for at least ten years and benefit from a one-time payment.

2.  easy installation, for you to save a large amount of labor and material costs: maintenance-free maintenance-free.

3.  No power, use temperature difference and natural wind to make the equipment rotate, save a large amount of operating costs, the effect is no less than other similar exhaust products.

4.  FRP negative pressure fan using the whole set of the Netherlands UBC New Zealand NSK sealed bearings, without lubrication. No motor, no power consumption, no noise, small size, light weight, high exhaust efficiency, easy installation.

   Application: commercial buildings and factories and mines (suitable for light steel structure roof) ventilation ventilation. Fiberglass negative pressure fan is to use the natural air convection principle, combined with its own structural design, the parallel direction of the air flow, accelerate and transform into vertical air flow from the bottom up, the utility model relates to a device for improving indoor ventilation and ventilation effect. It does not need electricity, no noise, can be long-term operation, exhaust indoor heat, smoke, odor, water vapor, etc. . The FRP negative pressure fan needs only a small amount of wind power to operate continuously for 951 days all year round. No electricity required. With high sensitivity, the turbine blade can be driven easily by a breeze or the difference between indoor and outdoor temperature. Improve the working environment and improve the working efficiency. Can bring you fresh air convection, remove hot air, exhaust or foul air.
