Fans AD1224HB-A70GL 120 × 25 mm 24 V 0.19 A case fan
A 120 mm DC axial fan with double ball bearings moves 87.87 CFM at 2200 RPM while drawing 0.19 A at 24 V
- Double ball bearing ensures long service life
- 2200 RPM rated speed delivers 87.87 CFM airflow
- 1 dB-A noise level suits quiet builds
- 24 V DC operation within 14.0 V to 27.6 V range
- 120 × 120 × 25 mm frame fits standard mounts
Purpose-fit 24 V axial fan
This 120 × 25 mm DC axial fan is designed for industrial and embedded systems that run on a 24 V rail. It suits builders who need a single-voltage cooling module for medical, rail, drive or hotel equipment. It is not for hobbyists who require PWM speed control or a 12 V connector.
Bearing and airflow impact
The double ball bearing supports continuous duty in harsh environments while the 2200 R.P.M. rotor delivers 87.87 CFM at 3.40 mmH2O static pressure. Acoustic output is rated at 39.1 dB-A. Buyers who need variable speed or lower noise at idle will not find those features here.
Mounting and wiring reality
The 120 mm square frame with 25 mm depth fits standard 120 mm mounting holes. Two-wire power input accepts a 14.0 V to 27.6 V range and draws 0.19 A nominal. No signal wire or fan-header adapter is included, so installers must provide their own 24 V source and connector.

Questions about this item
How long do the double ball bearings last before needing replacement?
Double ball bearings generally outlast sleeve alternatives and are rated for extended continuous operation at 2200 RPM.
What limits continuous 24 V operation first — thermal throttle or bearing wear?
At 3.12 W input power and 39.1 dB-A the motor runs cool enough that bearing life, not heat, sets the practical limit.
How loud and hot does the fan get after running all day at 2200 RPM?
Expect a steady 39.1 dB-A and only 3.12 W of heat dissipation, so case temperatures stay low even during 24/7 use.
