Industrial 24V Cooling Fan

The ADDA AQ1224HB-F51Size is a 120mm axial fan built for 24V systems in industrial, medical and transport equipment. It delivers 115.5 CFM airflow at 3000 RPM with a noise level of 46.8 DBA and a static pressure of 7.85 mmAq. The unit draws 0.32A for 3.85W power consumption and weighs 297g.

Upgrade from Lower-Voltage or Lower-Flow Fans

This model replaces 12V fans or units that cannot meet the 115.5 CFM target in 24V environments. The jump is worth it when a system requires the higher 24V rail, the 7.85 mmAq pressure for restrictive heat exchangers, or the 50000-hour rated life across a -40 to 75 °C operating range.

Fits 120mm Mounts with 38mm Depth

The frame measures 120 by 120 by 38mm, so it fits standard 120mm mounting holes while the 38mm depth must be cleared inside the chassis. It frees designers from larger centrifugal blowers in tight enclosures such as rail vehicles, medical carts or new-energy vehicle subsystems. The axial layout keeps installation depth minimal for heat-exchanger airflow.

Questions about this item

What mounting hole spacing does the 120 mm fan use?

The fan measures 120 mm square with a 38 mm frame depth, matching the standard 120 mm mounting pattern used in most cases and radiators.

How do I connect the 24 V 0.32 A leads without damaging the fan?

Wire the red lead to 24 V DC and the black lead to ground; reversing polarity will prevent the motor from starting and may cause permanent damage.

When should I plan to replace the fan based on its rated life?

The manufacturer rates the bearing life at 50000 hours of continuous operation at up to 75 °C ambient temperature.
