Centrifugal Fans Piping & Ducting Solutions

Description

A centrifugal fan is a mechanical device that is used for moving air and other gases. It is also known by the terms “blower” and “squirrel cage fan”. These fans increase the speed and volume of an airstream with the rotating impellers. The kinetic energy of the impellers is used by centrifugal fans to increase the volume of the air stream, which in turn moves them against the resistance caused by ducts, dampers, and other components. Air is radially displaced by centrifugal fans, changing the direction of the airflow. They are sturdy, quiet, reliable, and capable of operating over a wide range of conditions.

These fans are constant displacement devices or constant volume devices which means that at a constant fan speed, a centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed even though the mass flow rate through the fan is not. These fans are one of the most widely used fans and are predominantly used in the HVAC industry.

Centrifugal fans rely on blades for dragging air into circular motion with centrifugal forces speeding up airflow radially and outwards. These fans move air outward through ducts or tubes and provide a stronger and more stable airflow than axial fans.

In the HVAC industry, centrifugal fans are prevalent, and you can find them incorporated into building ventilation systems. Meanwhile, they’re often used for industrial processes to transport gas or materials. Air pollution control systems also utilize centrifugal fans, as they work well for dust control.

Centrifugal blowers can be seen with air conveyor systems, cooling and drying systems and in use for fluid bed aerators. Filter flushing, gas boosting, and sewage aeration are some other uses for them. Other places where the centrifugal fans can be seen in use include inside air conditioning units and furnaces, hairdryers, and in-car engines. The pressure volume curve is the key: centrifugal fans work better than axial types when working against a high-pressure drop.

Dutco Tennant LLC has been supplying centrifugal fans to countless businesses throughout the Middle East for more than four decades. As a one-stop-shop for commercial fan needs, we not only just sell fan, but also install and provide complete turnkey service.
