40×40×28 mm DC fan for 24 V systems

This 40 mm square axial fan measures 28 mm thick and runs on 24 V DC at 0.158 A. It uses a ball-bearing design and is built to the P6244028HB2F specification. The compact frame suits tight equipment bays where a 4028 footprint is required.

Replaces worn 24 V 4028 ball-bearing fans

Swap this unit in when an existing 24 V 40×40×28 mm fan develops bearing noise or reduced airflow. The jump is worth it when the original has failed or when a maintenance schedule calls for a fresh ball-bearing assembly in the same voltage and frame size.

Suits integrators needing a direct-fit 24 V 4028

Technicians servicing medical, rail, industrial or telecom gear that specifies this exact model will find a drop-in match. Builders who need a different voltage, a larger frame, PWM control or a different connector should look elsewhere.

Questions about this item

What clearance does the 40x40x28mm frame need to fit inside a case?

The fan measures 40 mm square and 28 mm deep, so allow at least that footprint plus a few millimetres for the lead wires and any mounting screws.

How do I mount the P6244028HB2F and what step is often missed?

Use four 3 mm screws through the corner holes; the step people miss is orienting the airflow arrow toward the component that needs cooling.

When should the ball-bearing fan be replaced?

Listen for new rattling or a drop in airflow; when either appears, swap the 24 V 0.158 A unit for a fresh P6244028HB2F.
