  • Strong static pressure of 11.66 mmH₂O overcomes resistance

Compact 24 V cooling fan

The YINGHUA AFB0424SHB is a 40 mm square frame fan designed for 24 V DC systems. It suits equipment such as inverters and printers that require targeted airflow in tight spaces.

Replaces larger or slower 24 V fans

When a chassis cannot accommodate a deeper or wider unit, this 15 mm thick model fits while delivering 11000 RPM and 0.420 m3/min airflow. The jump is worthwhile when the voltage rail is 24 V and the mounting pattern matches 40 mm centres.

Fits 40 mm mounts with two-pin power

The fan connects via a two-pin lead and operates across a 14.0 to 27.6 V range, drawing 0.18 A at 4.32 W. It leaves standard 40 mm screw holes free and adds only 41.5 dBA noise at full speed.

Questions about this item

Will the 40x40x15mm frame fit my inverter's fan slot?

The fan measures 40 mm square by 15 mm thick, matching the standard 40 mm mounting pattern used on many inverter and printer chassis.

How do I connect the 2-pin lead to a 24 V DC supply?

Connect the red wire to 24 V and the black wire to ground; the supply must stay within the 14.0 to 27.6 V range and deliver at least 0.18 A.

When should I plan to replace this 11000 RPM sleeve-bearing fan?

At 41.5 dBA the sleeve bearing will eventually wear; schedule replacement when noise rises noticeably or airflow drops below the rated 0.420 m3/min.
