GDSTIME 5020 24V Dual Ball Bearing Blower Fan with 25 cm Cable

GDSTIME 5020 24V centrifugal blower fan with dual ball bearings, a 2-pin XH2.54 connector and a 25 cm cable. Its nominal dimensions are 50 × 50 × 20 mm, making it 5 mm thicker than a 5015 blower.

The additional thickness accommodates a different impeller design and can be useful in ducts where directed airflow must be maintained against some resistance. Dual ball bearings make it suitable for machines subject to extended operation.

Compatibility

It is designed for assemblies compatible with 5020 24V centrifugal fans. Dimensions, mounting-hole positions, outlet orientation, connector and polarity must all be checked before installation.

It is not a direct dimensional replacement for a 5015 fan where the bracket only accommodates a 15 mm thickness. In that case, consider the GDSTIME 5015 24V dual ball bearing blower fan.

The additional thickness does not automatically provide better results in every printer. Final performance also depends on duct design, airflow restrictions and outlet position.

Installation and speed control

Confirm that the controller output supplies 24V and can correctly power the fan. Check the wire order of the XH2.54 connector before connection.

When using PWM control, configure a minimum power level that guarantees reliable startup. For part cooling, adjust the airflow according to the material and part geometry.
