DC centrifugal fans are mechanical devices that use rotating impellers to draw kinetic energy and push out air or gas in a particular direction. The housing or enclosure of the fan helps maintain the direction of the outgoing stream of air or gas. The kinetic energy of the rotating impellers increases the speed and volume of the outgoing stream of air or gas. These fans are also known as centrifugal blowers. The feature that distinguishes them from axial fans is the pressure ratio. When we say DC or direct current, the flow of electric current is unidirectional, unlike AC fans.
Miniature centrifugal fans are essential for efficient cooling in various applications, including electronics, industrial control systems, and greenhouse ventilation. These compact yet powerful fans are designed to ensure optimal airflow, preventing overheating and ensuring smooth operation.
As electronic devices become increasingly compact and powerful, effective cooling has become more critical than ever.
In the world of cooling and air movement, selecting the right type of fan is a decision that carries considerable weight—especially when working with compact systems, electronic enclosures, or industrial equipment.
