Exhaust fans are widely used in homes and public places; exhaust fans are divided into partition wall type (both sides of the partition wall hole are free spaces, and the air is exchanged from one side of the partition wall to the other side), duct exhaust type (one side enters the air from the free space, while the other side exhausts the air through the duct), ducted air intake type (one side enters the air through the duct, while the other side exhausts the air to the free space), full duct type (exhaust fan on both sides Install the duct, through the duct air intake and exhaust). According to the wind flow form, it can be divided into centrifugal type (the air enters in the direction parallel to the rotation axis and is discharged in the direction perpendicular to the axis), and axial flow type (the air enters in the direction parallel to the rotation axis and is still discharged in the direction parallel to the axis) And cross-flow type (the entry and exit of air are perpendicular to the direction of the axis.
