In industries when there is a requirement for larger volumes of air flow at higher pressures blowers are used. A fan with higher pressure ratio (output pressure / input pressure) can be called as a blower provided it produces pressures as high as 1.20 kg/cm2. Like fan systems, blowers are widely used in industrial processes where a constant flow of air/gas is needed at higher pressures such as conveying material in dust collector systems, combustion air for burners, drying & cooling, general ventilation & circulation of air and more. In industrial vacuum systems where suction or negative pressures are required, blowers with higher efficiency are also used.

Industrial blowers are usually classified into two types, centrifugal blowers and positive-displacement blowers. With their wide operating ranges and high speed capabilities centrifugal blowers have several advantages over other blower types.

With blades rotating at about 15,000 rpm, centrifugal blowers are constant volume devices and are designed with high speed impellers. The speed of the air stream entering into the blower is increased by the impeller or blades, where it gains kinetic energy and accelerates with higher pressure through outlet in radial direction. These blowers like centrifugal fan systems also have different drive mechanisms such as belt, variable and direct driven. Centrifugal blowers are fitted with dampers & louvers, ducts and other similar airflow resistant components to adjust the air flow rates.

It can be single or multi-stage unit and can have different blade orientations such as radial, forward curved and backward curved. When a uniform airflow is required single stage centrifugal blower are commonly used and when there is a requirement for varying flow of air at a fixed pressure multi-stage blower are useful.

These blowers are classified into three types based on their ability to generate pressure during operation. They are low pressure, medium pressure and high pressure centrifugal blowers.

Centrifugal blowers operate at high impeller speeds and are useful in industrial applications to move bulk volumes of air at low-to-medium static pressures in radial direction. With various blade configurations centrifugal blowers operate in a wide range of environments and in diverse airflow/pressure conditions. These blowers can develop more pressure at a given rotational speed compared to other type of blowers at the same rotational speed. Since centrifugal blowers have high horsepower capability than the other blowers, there will be less overloading and possible damages to motor. With multiple sizes & blade arrangements, they can be better choice for places where space is a premium.

These blowers are widely used in industrial applications where there is a requirement for constant flow of larger volumes of air such as in ventilation, dust control, air conveyor systems, industrial vacuum applications, combustion, transporting materials, cooling and heating systems, and in other industrial processes.

Based on their air flow capacity, blower type, blower dimension, and maximum operating pressure centrifugal blowers vary. Based on the requirement, blowers of various types can be customized and installed to serve the needs of diverse industrial applications.

 On the basis of their air flow capacity in blower type, blower dimension, and maximum operating pressure centrifugal blowers vary. Blowers of various types can be customized and installed to serve the needs of diverse industrial applications based on the requirement. In our next blog we shall talk on positive displacement blowers and other blowers.
