A-BX centrifugal fan is suitable for ventilation in industrial and mining plants, scientific research institutions and large public buildings. It can be used to take in air or distribute air. The air distributed gone through spontaneous combustion, harmless to human body, without any corrosive gas to steel materials, nor viscous substances in the gas, dust and hard particles contained in it are not more than 150mg/m3. A-BX centrifugal fan, also known as explosion-proof centrifugal fan, is used for ventilation of flammable and volatile gas, but it is not suitable for use in technological process, and the temperature of conveying gas should not exceed 80 degrees Celsius. The fan can be engineered into two types: right-rotating and left-rotating. Looking at the rotation direction of the impeller from the motor end, clockwise rotation is right-rotating, and counterclockwise rotation is left-rotating There are four transmission modes of the fan: A, B, C, and D. For the ease of convenience to install and debug, it can also be used for the overall support and shock-absorbing support of the steel structure.
