An industrial fan is different from the regular general-purpose fans in several ways. A regular fan is generally used for residential or slightly commercial purposes. But an industrial fan is especially used for providing a large flow of gas or air to various processes across different industries.
Industrial fans are very heavy-duty fans. They are made up of stronger materials & components in order to smoothly operate for a longer period of time. These industrial fans are designed to provide a greater pressure and flow of air which is required for several industrial operations.
The industrial fans are majorly categorized into one of the following types.
- Centrifugal Fans: Centrifugal fans are popularly known as blowers and they find the best application in high-pressure industries. There are several advantages of centrifugal industrial fans when compared to axial fans in various prime parameters like durability, energy efficiency, versatility and low maintenance. Centrifugal industrial fans are designed in such a manner that they can handle various types of air & different pressure. Centrifugal industrial fans also come in various sizes. There are six major types of centrifugal fans which are defined on the basis of the blade configuration. Every type of centrifugal fan is designed for different and specific application range and has different abilities to perform various industrial processes. These six types of centrifugal fans are backward inclined fans, squirrel cage, airfoil blade fans, radial blade fans, inline and radial tip centrifugal fans. Centrifugal industrial fans are majorly used in various applications like heating and cooling processes, air handling units, boiler combustion and electronic cooling.
- Axial Fans: Axial fans are popularly known as propeller fans. They have the capacity of providing large volumes of air and at a much lower pressure. This process is used to make the air enter and leave the fan along the axis. This strategically designed axial fan works using the axial forces in order to achieve the effective movement of gas or air. This is achieved by the spinning of the fan in a central hub where the blades are extended radially towards their outer diameter. These types of industrial fans are used for extraction applications and simple cooling. Axial fans are again classified into sub-categories, each of which is made in different ways and have different applications.
- Mixed Flow Fans: This particular fan type is a combination of the features of both the centrifugal and axial types and is majorly being employed for air movement techniques of both. The overall pressure development of this mixed flow fan is certainly greater than that of axial fans. These fans are generally used for moderate commercial ventilation applications and residential purposes.
- Tangential fan: These are barrel-shaped industrial fans which are equipped with curved forward blades and are several times longer than the given diameter. These particular fans majorly tend to scoop up the air and deliver relatively lower pressure at a longer length. These fans are ideally used for cabinet cooling or air coverage. They are known to provide absolutely smooth laminar airflow and are widely used in air curtains, air conditioners, industrial racks, computer systems, ovens, convector fans, ventilators and dehumidifiers.
Industrial fans have several uses and are being widely used as per the requirement of various industries. The above discussion may help you choose the best industrial fan as per your usage.
