Squirrel cage fans, also known as centrifugal blower fans, are essential components in modern ventilation, cooling, and air circulation systems. Their unique design, characterized by a cylindrical wheel with curved blades, enables these fans to move large volumes of air efficiently while maintaining a compact footprint. Among the various configurations available, 12V high efficiency squirrel cage fans are especially popular in automotive, electronics, and portable ventilation applications due to their energy-saving capabilities and adaptability to low-voltage power sources.
