A centrifugal fan, also known as a rotor ventilator, is a mechanical device that helps to circulate air within an enclosed space. It works by using the kinetic energy of a spinning impeller to create a flow of air, which can then be directed where needed through ducts or vents. This type of fan is commonly used in HVAC systems for heating and cooling purposes, as well as in industrial settings for ventilation and dust control.
