Characteristics of FRP negative pressure exhaust fan
The protection level of the special motor for the aluminum shell fan produced using advanced foreign technology. Long service life, smooth operation and low noise.
The fan shell is made of fiberglass that does not decompose for many years. It has the characteristics of acid and alkali resistance, corrosion resistance and long service life. At the same time, it reduces the phenomenon of resonance due to the large amount of metal materials in the whole machine.
Based on the principle of flow mechanics and wind flow, we use/optimize the design to manufacture blades with reasonable air volume and noise at angles. The blades are made of glass fiber reinforced plastic, which will not age or deform.
Using the principle of air flow, the pneumatic blinds are designed and made to automatically open and close rain-proof without electricity.
Belt-free, you don’t have to worry about maintenance.
