Product Introduction

On the basis of absorbing new technology inside and outside China, Changsha Blower Co.,Ltd. and Xian Jiaotong University teamed up to develop the centrifugal blowers, that include multistage low speed centrifugal blowers, single-stage low speed centrifugal blowers and single-stage high speed centrifugal blowers, three series, more than 100 models, with the capacity 50～2000m3/min and pressure rise 10～150kPa.

With its capacity ranging from 200 to 2000m³/min, and pressure rise less than 34.3kPa, the A series centrifugal blowers have two kinds of construction , AI single-stage cantilever and double supporting, they are used to convey air, coal gas, sulfur dioxide.

Derived Models

The following models are derived from the above three models:

●Sewage treatment blower capacity: 50～600m³/min pressure rise:49.0～98kPa

●Desulfurization&oxidation blower capacity: 60～800m³/minpressure rise: 49.0～150kPa

●Sulfur dioxide blower capacity:200～2000m³/minpressure rise: 26.4～53.9kPa

●Gas-making furnace blower capacity: 300～1500m³/minpressure rise: 23.5～34.3kPa

●Cupola blower capacity:50～350m³/minpressure rise: 9.8～29.4kPa

●Smelting furnace blower capacity:100～1000m³/minpressure rise: 49.0～150kPa

●Coal gas blowercapacity:100～1250m³/minpressure rise: 19.6～53.9kPa

●Coal flotation&washing blowercapacity:50～500m³/minpressure rise:19.6～68.6kPa

Model Selection

Model Introduction

For example：

C300–1.7/1.0

It means a multistage centrifugal blower, when temperature is 20℃, intake pressure is 1.0kgf/cm²（98kPa）, relative humidity is 50%, the capacity is 300 m³/min, and discharge pressure is 1.7kgf/cm²(pressure rise 68.6kPa).

Model Selection Drawing

● Features:

◎ Due to the advanced design of aerodynamic, the impeller is of high efficiency..

◎ The casing is of horizontal division welding structure, simple and light in weight.

◎ The advanced wearing-resistant and anti-adhesion technology is applied to deal with the medium with many dust, so the service life of blower is long.

◎ Flat performance curve means the stable working range is wide.

◎ AI single-stage and cantilever construction is applied to the blower with small and medium capacity.

◎ AII single-stage and double supporting construction is applied to the blower with large capacity.
