Compared with the former axial roof fan, this series fan is a new product and it has the characteristics of high efficiency, low noise, corrosion resistance and high precise stabilization.
It has large amount of wind and lower pressure than centrifugal fan. So it is applied to such occasions with medium lower pressure, large amount of air flow. It can be designed as two ways rotary reversible with equivalent effect.
Apart from the transmission components, all the other parts adopt FRP material with import coating, beautiful surface, gracious and durable characteristics. 
According to the customer's requirements, we also design special fans which are able to exhaust the explosive, corrosive and high temperature gas.

Advantages:
# Compact design for installation on metal and cemet roof 
# Equipped with durable waterproof cover
# Minimal noise level
# Highest airflow performance.

# Anti-insects shutter closes to prevent insects and airflow backward.
