80mm DC axial fans from MAX FLOW

MAX FLOW has supplied industrial cooling fans since 1984. This page lists our 80mm DC brushless (BLDC) axial fans: 11 models and 199 part numbers across 10/15/20/25/32/38 mm frame depths, in 5V, 12V, 24V, 48V DC. Airflow ranges from 13.9 to 133.9 CFM, speed from 2000 to 16000 RPM and noise from 22 to 73.8 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 80mm DC axial fan

  • Highest airflow: MFD8038B (12V) delivers 133.9 CFM at 10000 RPM and 66.6 dB(A), with 50 mmH2O static pressure.
  • Highest static pressure: MFD8038C (12V) has a maximum static pressure of 112.6 mmH2O (max. airflow 132.5 CFM), the better choice when the airflow path has dense fins or filters.
  • Quietest: MFD8025D (12V) runs at 22 dB(A) with 24.7 CFM at 2150 RPM.
  • Thickness matters: the 10mm-deep fans reach up to 25.6 CFM and 2.4 mmH2O, while the 38mm-deep fans reach up to 133.9 CFM and 112.6 mmH2O. Choose the thinner frame when space is tight and the thicker frame when static pressure is the constraint.
  • Voltage: 5V / 12V / 24V / 48V DC rails are available across the 80mm range (check each datasheet, since not every model comes in every voltage).

Bearing, operating temperature and life

Bearing options: Ball Bearing / Sleeve Bearing. Operating temperature: Ball Bearing: -10 ~ 70°C / Sleeve Bearing: 0 ~ 60°C. Life expectancy: Ball Bearing: 50,000 hours at 25°C / Sleeve Bearing: 30,000 hours at 25°C. For continuous 24/7 operation in warm equipment, ball bearings are the usual choice; sleeve bearings suit cooler, cost-sensitive or low-vibration applications. See How to Choose an Industrial DC Cooling Fan for the full 9-step selection framework.

80mm DC axial fan FAQ

What voltages are available for 80mm DC axial fans?

MAX FLOW 80mm DC axial fans are offered in 5V, 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 80mm DC axial fan deliver?

Across MAX FLOW 80mm DC axial fans, maximum airflow ranges from 13.9 to 133.9 CFM depending on model, thickness and speed. The highest is MFD8038B at 133.9 CFM.

Which 80mm DC axial fan is the quietest?

The quietest rated variant is MFD8025DD1-LLB at 22 dB(A) (24.7 CFM, 2150 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 80mm 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.
