4020 24V Ball Bearing Axial Fan with 1 m Cable

4020 24V axial fan with a ball bearing system and a 1 metre power cable. Its 40 × 40 × 20 mm format is suitable for cooling heatsinks, electronics and compact equipment that can accommodate a 20 mm thick housing.

The ball bearing system is intended for frequent or extended operation, particularly where reduced wear is preferred over a basic axial fan.

• 3D printers, CNC machines and automation.

Compatibility

It can be used as a replacement or upgrade in equipment designed for 4020 24V axial fans. Dimensions, mounting pattern, connector, polarity and airflow direction must all be checked.

The additional depth compared with a 4010 fan may improve performance against some restrictions, but prevents installation in brackets that only accommodate a 10 mm thickness. Final performance also depends on the heatsink, grille or duct being used.

For a standard alternative with a shorter cable, see the 4020 24V axial fan with 17 cm cable.

Installation and speed control

Confirm that the output supplies 24V and check the polarity before connection. The output must support the fan's operating consumption and starting current.

When using PWM control, configure a minimum setting that guarantees startup. After installation, check that the airflow direction matches the intended cooling arrangement.
