24 V 4028 inverter fan

This 40 × 40 × 28 mm axial fan runs on 24 V or 26 V and draws 3.6 W to 4.1 W. It uses a double ball bearing and a two-wire connection for simple power delivery. The unit is supplied new from the original factory source.

Installers who need a compact 24 V axial fan

The two-wire design suits installations that only require on-off power without speed reporting or PWM control. Builds that depend on speed feedback, variable-speed headers or a different voltage rail cannot use this model.

Double ball bearing at 4.1 W

The double ball bearing handles continuous duty in industrial and networking chassis. Input power reaches 4.1 W at the upper voltage, so the supply must deliver that headroom.

Questions about this item

How can I confirm the PMD2404PQB1-A is spinning correctly after installation?

Connect the 2-wire lead to a 24 V DC supply and verify the fan draws approximately 3.6 W to 4.1 W while the double ball bearing runs smoothly without vibration.

What comes in the box with the 4028 inverter fan and what must I source separately?

The package contains the 40 × 40 × 28 mm fan unit only; you will need to provide a 24 V DC power source and any mounting screws or adapters required for your chassis.

Which voltage rating should I select for the PMD2404PQB1-A — 24 V or 26 V?

The fan is rated for 24 V DC nominal operation with a 26 V maximum input; choose a 24 V supply for standard use and ensure your source does not exceed 26 V.
