The scroll housing is a key component of this type of fan. It consists of a curved or spiral-shaped casing that surrounds the fan wheel or impeller. The impeller is typically a set of blades or vanes mounted on a rotating shaft. As the impeller rotates, it draws air into the center of the scroll housing and then forces it to move in a radial direction towards the outlet.
The scroll housing plays an important role in increasing the efficiency of the fan by converting the kinetic energy of the rotating impeller into pressure energy. The curved shape of the housing gradually accelerates the airflow and creates a pressure difference, allowing the fan to generate higher static pressures compared to other types of fans, such as axial fans.
Centrifugal fans with scroll housings are commonly used in applications where there is a need for increased static pressure or where space is limited. They are often found in HVAC systems to move air through ductwork, as well as in industrial processes that require ventilation, exhaust, or air circulation.
