Generally speaking, exhaust fans are classified according to the air outlet, which can be divided into partition wall type (both sides of the partition wall hole are free spaces, and air is exchanged from one side of the partition wall to the other), duct exhaust type (one side takes air from the free space, while the other side takes air through the duct) and duct intake type (one side takes air through the duct, and the other side takes air through the duct). At the same time, according to the form of air flow, it can be divided into centrifugal type (air enters from the direction parallel to the rotating shaft and is discharged in the direction perpendicular to the shaft), axial type (air enters from the direction parallel to the rotating shaft and is still discharged in the direction parallel to the shaft) and cross-flow type (air enters and is discharged in the direction perpendicular to the shaft).

2. Divided by ventilation mode

If divided by ventilation mode of exhaust fan, it can be divided into three types: exhaust type, suction type and combined type. The exhaust type means that air enters from the natural air inlet, and then dirty air can be exhausted through the exhaust fan; Suction type passes through the ventilator, then fresh air is inhaled, and dirty air is discharged from the natural exhaust port; The combined type is that both suction and exhaust are completed by the ventilator.
