What are the three types of fans?
Mechanical engineering, ventilation systems, and aerodynamic applications categorize standard air-moving fans into three primary operational designs based on airflow direction. The first is axial fans, which feature blades that rotate around an axis, moving air parallel to the shaft, making them ideal for high-flow, low-pressure applications like computer cooling and room ventilation. The second is centrifugal fans, also known as blowers, which draw air into a scroll-shaped housing and expel it at a right angle through centrifugal force, generating high pressure suitable for ductwork and HVAC systems. The third is mixed-flow fans, which combine design elements of both axial and centrifugal fans to deliver efficient airflow performance under moderate pressure constraints.
