Exhaust fan, also known as ventilation fan, is a type of air conditioning device that is driven by an electric motor to rotate the fan blades and drive the airflow, allowing for the exchange of indoor and outdoor air. The purpose of exhaust is to remove indoor polluted air, regulate temperature and humidity, and is widely used in households and public places.

Classification of exhaust fans

Classification of exhaust fans

Divided by intake and exhaust ports The exhaust fan is divided into partition type (both sides of the partition hole are free spaces, and air is exchanged from one side of the partition to the other), duct exhaust type (one side is intake from the free space, and the other side is exhaust through the duct), duct intake type (one side is intake through the duct, and the other side is exhaust to the free space), and full duct type (both sides of the exhaust fan are equipped with ducts, and air is intake and exhaust through the duct). According to the form of airflow, it is divided into centrifugal (air enters parallel to the axis of rotation and exits perpendicular to the axis), axial (air enters parallel to the axis of rotation and exits parallel to the axis), and cross flow (air enters and exits perpendicular to the axis).
