Application Area

a. The altitude does not exceed 2000m;

b. Ambient atmospheric pressure 80~110kPa;

c. Ambient temperature -20~40 °C;

d. The relative humidity of the surrounding air is not more than 95% (at 25 ° C);

e. There are flammable gases in Groups IIA to IIC and T1 to T4, and explosive gas mixture formed by steam and air in Zone 1 and Zone 2 hazardous sites;

f. where there is no significant vibration;

g. In an environment where there is no damage to metal-insulated gases and vapors.

Main structure and parameters

a. Air tube: The machine base is made of FRP/carbon steel, which has the characteristics of light weight and corrosion resistance, and is perfectly integrated with the structural design of the building.

b, hood: made of glass steel, high strength, suitable for outdoor use.

c. Blade: Made of fiberglass, high strength and long service life.

d, louver: The flap of the flap is gravity type, which can be automatically opened. When the fan stops running, the damper is closed to reduce the loss of heat in the winter room.

e, anti-bird net, safety net: stainless steel mesh, good safety performance.

f, motor: low noise motor, stable performance.
