DC Equipment-Cooling Fans

Running on 48V DC power or lower, these compact fans fit inside electronics and other small, heat-sensitive equipment to keep things cool. They're also known as muffin fans. Some meet American and Canadian safety standards.

Square

Ball Bearing—Fans with ball bearings generate less heat as they run, so they have a longer life than fans with plain bearings.

Plain Bearing—Fans with plain bearings are good for less demanding applications, such as cooling prototypes or parts that aren’t used often.
