“A centrifugal fan is a type of mechanical device used to create a flow of air or gas. It’s also commonly referred to as a radial fan or a blower. Centrifugal fans are designed to generate a high-pressure airflow by using the kinetic energy imparted to the air as it enters the fan housing and is then accelerated radially outward from the center of the fan wheel.
The basic design of a centrifugal fan consists of a rotating impeller (wheel) that contains blades or vanes, housed within a casing or housing. When the impeller rotates, it draws air or gas into the center of the fan and then throws it outward at a right angle to the intake direction. This radial acceleration of air creates a pressure difference between the inlet and the outlet, resulting in the generation of a higher-pressure airflow.
Centrifugal fans are often used in various applications where there’s a need for moving air or gas against resistance, such as in HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial ventilation, dust collection, drying processes, cooling systems, and more. They are particularly effective when there’s a requirement for high pressure or airflow rates.
Compared to axial fans (where the airflow direction is parallel to the fan’s axis of rotation), centrifugal fans can handle more challenging applications due to their ability to generate higher pressures. They’re available in various sizes and configurations to suit different needs and can be single-inlet or double-inlet depending on the specific application.”
