120mm DC axial fans from MAX FLOW

MAX FLOW has supplied industrial cooling fans since 1984. This page lists our 120mm DC brushless (BLDC) axial fans: 14 models and 204 part numbers across 25/37/38 mm frame depths, in 12V, 24V, 48V DC. Airflow ranges from 47.3 to 311.7 CFM, speed from 1450 to 11000 RPM and noise from 23 to 77.3 dB(A), so you can match the fan to the static pressure and noise budget of your equipment. Control options include PWM speed control, FG tachometer feedback and RD lock-alarm output, and IP55 or IP68 waterproof variants are available on select models. Custom voltage, speed and wiring are available on request.

How to choose a 120mm DC axial fan

  • Highest airflow: MFD12038E (24V) delivers 311.7 CFM at 11000 RPM and 70.8 dB(A), with 162.9 mmH2O static pressure.
  • Quietest: MFD12537 (12V) runs at 23 dB(A) with 47.3 CFM at 1450 RPM.
  • Thickness matters: the 25mm-deep fans reach up to 174.5 CFM and 54.3 mmH2O, while the 38mm-deep fans reach up to 311.7 CFM and 162.9 mmH2O. Choose the thinner frame when space is tight and the thicker frame when static pressure is the constraint.
  • Voltage: 12V / 24V / 48V DC rails are available across the 120mm range (check each datasheet, since not every model comes in every voltage).

120mm DC axial fan FAQ

What voltages are available for 120mm DC axial fans?

MAX FLOW 120mm DC axial fans are offered in 12V, 24V, 48V DC. Not every model is available in every voltage, so confirm the rated voltage on the datasheet of the model you choose.

How much airflow does a 120mm DC axial fan deliver?

Across MAX FLOW 120mm DC axial fans, maximum airflow ranges from 47.3 to 311.7 CFM depending on model, thickness and speed. The highest is MFD12038E at 311.7 CFM.

Which 120mm DC axial fan is the quietest?

The quietest rated variant is MFD12537D1-M at 23 dB(A) (47.3 CFM, 1450 RPM). Noise rises with speed, so pick the lowest speed that still meets your airflow and static pressure requirement.

Where can I find the P-Q curve and dimensions of a 120mm DC axial fan?

Every model listed on this page links to a datasheet with the dimension drawing, P-Q curve and the full part number table.
