Industrial axial fan for 220 V environments

The Fans AA1252MB-ATSize is a 120 × 120 × 25 mm axial fan designed for direct connection to 220 V mains at 50 or 60 Hz. It suits industrial equipment, medical devices, rail systems and other installations that require hot or cold air exchange without a separate low-voltage supply.

Sustained airflow at two fixed speeds

At 50 Hz the fan draws 0.11 A and 20.7 W, spins at 2050 RPM and delivers 61 CFM at 3.508 mmAq static pressure. At 60 Hz it draws 0.10 A and 18.4 W, reaches 2400 RPM and provides 69.4 CFM at 3.912 mmAq, giving consistent cooling across both mains frequencies.

Rated noise and long service life

Acoustic output is 38.7 dBA at 50 Hz and 44.1 dBA at 60 Hz under normal operation. The unit is rated for 50000 hours of continuous use in ambient temperatures from -25 °C to 75 °C, and its axial layout keeps installation depth minimal while maintaining efficiency.

How loud is the AA1252MB-ATSize fan when running continuously at 50 Hz and 60 Hz?

The fan produces 38.7 dBA at 50 Hz and 44.1 dBA at 60 Hz, so expect a low hum that stays consistent during all-day operation.

Does the AA1252MB-ATSize connect to a standard motherboard header or does it need a separate 220 V supply?

It requires a 220 V AC supply at 50/60 Hz drawing 0.11/0.10 A; it does not plug into a 12 V motherboard fan header.

Will the 120 × 120 × 25 mm frame of the AA1252MB-ATSize line up with the mounting holes on my older 120 mm case openings?

Yes, the 120 mm square frame and 25 mm depth match the standard 120 mm mounting pattern used on older cases.
