What type of fan handles the entire flow in an airway to increase air circulation?

The correct answer is a booster fan. In mining ventilation systems, a booster fan is specifically designed to enhance airflow in certain areas of the mine by increasing the air volume or pressure. They do this by being strategically placed to support the main airflow, especially in areas where resistance and turbulence may reduce circulation. This ensures an adequate supply of fresh air reaches all parts of the mine, maintaining safety and efficiency in operations.

Booster fans are generally used to overcome the pressure losses that occur in ventilation ducts or airways, which can happen due to bends, changes in cross-sectional area, or obstructions. Their ability to handle the entire flow in an airway makes them essential for effective ventilation, ensuring that all required areas receive sufficient airflow.

Other types of fans, such as exhaust fans, are primarily used to remove air from a specific area, while inline fans are typically used for venting or circulating air within ducts but may not be capable of managing the full airflow required in larger airways. Centrifugal fans, while effective at generating airflow, often serve as primary fans in the system rather than being placed to boost airflow within existing pathways. Each of these fans plays a different role, but it is the booster fan that is specialized for enhancing total airflow in designated
