Forward curve fans are most commonly used in high-temperature furnace applications, and ventilation applications where there is a low chance of dust loading. These fans have squirrel cage impellers, which generate the highest airflow volume. Thus, they are more appropriate for clean air applications. Dust buildup is one of the drawbacks of this fan. These fans assure high efficiency as well as quiet operations. Airfoil fans are used in applications where ambient or elevated temperatures are involved such as chemical, power generation, metals, resource recovery industries, and so on. Airfoil Fans:Ĭentrifugal fans are named so owing to their airfoil-profiled blades. Let’s see the other three fans, in brief, to understand how they differ from radial fans. Of these, the forward curve, backward curve, airfoil fans, and radial fans are the most popular ones. There are several types of centrifugal fans, which are distinguished based on their designs. These fans may be belt-driven or motor-driven. The airflow is induced by the centrifugal force, which is produced in a rotating column. The accelerated air is discharged radially, thus, the name. In radial fan, the air hits the fan wheel, turns at the right angle, and is accelerated by radial flat blades on the impeller.
What are the components of Radial Fan?Ī radial fan mainly comprises the following: This air that it lends works upon is usually sucked from the sides of the fan and it is blown through the outlet of the fan. The impeller rotates on its own and provides direction to the air. Are you intrigued to know what makes these fans popular? If so, this post answers everything you want to know about these fans.Ī radial fan is a mechanical device that features an impeller, which is powered by an electrical motor. Owing to their distinct advantages, today, it is easy to find these fans in different designs. These fans are also known as paddle wheel fans or radial plate fans, air blower fans, squirrel cage fans, and squirrel fans depending on their construction and operation.
These fans are used in factories, mines, and commercial buildings. Widely known as centrifugal fans, the radial fans are also used to move gases, moisture, and dust in the direction of incoming fluid. Radial fans are one of the important types of industrial fans to have received wide acceptance. Over the years, various types of industrial fans have gained immense torque across industries.
