BDWT Explosion proof Axial flow roof fan (lower noise)-- Nanyang YITONG

BDWT Explosion proof Axial flow roof fan (lower noise)

BDWT Explosion proof Axial flow roof fan (lower noise) are widely used in petroleum, chemical, electric power, military, medicine and other industries. It is to send and exhaust dangerous places and factories, mines, buildings and other ventilation.

According to the different requirements of pressure, air volume and noise in the application, the following three types of fans can be selected: BDWT-I axial flow type explosion-proof roof fan: it has the characteristics of large air volume and low pressure compared with centrifugal fan. In the occasion of medium and low pressure and large flow, it can be designed as a two-way rotary reversible according to the needs of users, and has the characteristics of equivalent forward and reverse working conditions. BDWT-II, BDWT-III centrifugal explosion-proof roof fan is suitable for occasions with small air volume and high pressure. BDWT-III type fan is especially suitable for use in places where the roof is clean and clean.
In addition to the transmission components, the fan is made of FRP (glass reinforced plastic) material, and the surface is made of imported gel coat resin film. The surface transition is soft, beautiful, practical, and has a long service life.
The fan has small rotation inertia, high dynamic balance accuracy and stable operation.
For the occasion of sending and discharging flammable, explosive, corrosive and high-temperature gas, the fan can also be specially designed to be explosion-proof and anti-corrosion type, which can be used by customers.

PRODUCT DETAILS

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.
