A blower is a mechanical device that is used to transport air from one place to another by means of a mechanical device. There are many different types of blowers, including Roots blowers, centrifugal blowers, rotary blowers, and axial flow blowers, each of which has its own unique working principles and uses.

The Roots blower is a fixed volume blower whose air volume is proportional to the number of revolutions, and is widely used in various industries, such as petrochemical, electric power, metallurgy, food and pharmaceutical, and cement and building materials, because of its high mechanical strength, low noise, and low vibration. It provides sufficient gas power for enterprises through its unique working principle and structural characteristics.

The centrifugal blower is a constant pressure blower with little change in wind pressure, and its low rotational speed, low noise, low vibration and high efficiency make it widely used in fields such as the water treatment industry and the paper-making industry.

The rotary blower belongs to the constant flow fan, its low rotational speed, low noise, low vibration and high efficiency make it has a wide range of uses in environmental protection engineering, can effectively clean sewage.

The axial flow blower is suitable for large flow and low pressure, and it is needed in living facilities, industrial production, office areas, large construction sites, large production sites, agricultural production and other fields.

In general, the function and use of the blower is very wide, it can be used to transport air, gas, liquid and other kinds of media, but also can be used to purify the air, adjust the temperature, control the pressure and so on. In various industries and fields, blowers play an important role, providing convenience and protection for people's production and life.
