Delta AFB1224SH 120 mm 24 V fan

The Delta AFB1224SH is a 120 mm axial case fan that runs on 24 V DC and draws 0.42 A for 10.08 W. It spins at 3400 RPM and delivers 113.11 CFM of airflow at a rated noise level of 46.5 dBA. The frame measures 120 x 120 x 25 mm, fitting standard 120 mm mounting points in industrial and embedded enclosures.

Sustained-load behaviour

At continuous 3400 RPM the motor maintains the rated 113.11 CFM without the drop-off seen in short-burst specifications. The 24 V supply and 10.08 W power draw stay stable, so thermal performance remains predictable during long duty cycles in medical, rail or industrial equipment. Acoustic output holds at the quoted 46.5 dBA once the bearing settles.

Upgrade context

This fan replaces lower-airflow 120 mm units that cannot meet the 113.11 CFM requirement in 24 V systems. The step up is justified when equipment specs demand higher static pressure or when an existing 24 V fan has worn bearings and rising noise. It is not a drop-in for 12 V or 5 V rails, nor for builds that need PWM speed control or quieter operation below 40 dBA.
