Product Introduction
　　AⅠseries centrifugal blower is widely used in metallurgy, chemical industry and other fields, the conveying medium is air, gas, SO2 mixed gas and so on. The fan is a single-stage cantilever support structure and axial inlet。Its main features: high efficiency, easy to install and overhaul, good sealing performance.Flow range: 60～1300m3/ min, Pressure range: 15～45kPa.

　　Structural Features
　　①The shell adopts advanced fluid analysis method to design, the material is cast iron or steel plate （welded structure）, the upper and lower part, easy to install and overhaul;
　　②The impeller adopts binary or ternary flow technology design, high efficiency; The rotor group is adjusted by static and dynamic balance, and the operation is stable.
　　③The sealing structure is mature and reliable, which can effectively prevent gas leakage and meet the requirements of different working conditions.
　　④The blower adopts rolling bearing or sliding bearing, the rolling bearing adopts grease lubrication or oil lubrication water cooling but the sliding bearing uses pressure forced oil lubrication.

　　The Parameter Range

　　Ordering Instructions:

　　The user needs to provide the following parameters when ordering the fan: the atmospheric pressure （or altitude） used by the fan, the transmission medium, the medium composition and percentage of medium composition （mixed gas）, inlet temperature, relative humidity, inlet flow （volume flow or mass flow）, pressurization, dust content, corrosion resistance explosion resistance and other requirements （special gases）, and other water, electricity and gas conditions.
　　The rotation direction and angle of the fan can be designed according to the requirements of the user to meet the demands of various working conditions of the user.
