Product Introduction
　　AII series centrifugal blower is widely used in the industry of environmental protection, metallurgy, chemical industry and so on. The conveying medium is gas, air, SO2 mixed gas and so on.?The series of centrifugal blowers are single stage impeller, double support structure, single inhalation or double intake air intake.?The speed is less than 3000r/min, the flow range is 300～20000m3/min, and the boost range is 10～45kPa.

　　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.
