Understanding The Components Of A Squirrel Cage Fan


A squirrel cage fan is a common type of fan used in various applications. It consists of several components, including a motor, rotor, bearings, and fan blades. The motor rotates the rotor, which moves the air through the fan blades.

The bearings provide support and reduce friction, allowing the rotor to spin smoothly. Squirrel cage fans are available in different types depending on their application, such as centrifugal fans, axial fans, and mixed flow fans. Centrifugal fans are commonly used in ventilation systems and air conditioning units.

Axial fans are suitable for high air volume and low-pressure applications, while mixed flow fans are ideal for medium to a high-pressure environment. Understanding the components and types of a squirrel cage fan can help you wire and maintain it properly.
