  • Air Flow15-20 CFM
  • High airflow with 84/120 CFM ratings
  • Low noise at 45 dB-A operation
  • Ball bearing rated for 60000 hours
  • Wide temperature range from -20°C to 85°C
  • Corrosion-resistant aluminium alloy frame

Industrial AC axial fan for continuous airflow

The Fans SJ1238HA2 is a 120 × 120 × 38 mm AC axial fan designed for 220 V mains supply. It uses a ball-bearing assembly rated for 60 000 hours at 40 °C ambient temperature. The die-cast aluminium frame resists corrosion and moisture in harsh environments.

Suited for rack enclosures and industrial cabinets

Buyers who need a mains-powered fan for server racks, telecom cabinets or equipment enclosures will match the 84 to 120 CFM airflow range. Builders looking for a low-voltage PWM fan for a desktop PC or a silent home-theatre build should look at something else.

Steady output during non-stop operation

At the high-speed setting of 3 000 RPM the fan delivers 120 CFM while producing 45 dB-A of noise. Power draw sits at 15 to 21 W, and the ball-bearing design maintains consistent speed and airflow over 24-hour duty cycles without the wear seen in sleeve-bearing units.

Highlights

  • High airflow with 84/120 CFM ratings
  • Low noise at 45 dB-A operation
  • Ball bearing rated for 60000 hours
  • Wide temperature range from -20°C to 85°C
  • Corrosion-resistant aluminium alloy frame

Questions about this item

What power supply voltage must my system provide for the 220 V model to run?

The fan is rated for 220 V AC; your equipment must supply mains-level 220 V power to operate it.

Will the 120×120×38 mm frame and ball bearing fit the same mounting holes as my existing 120 mm fans?

Yes, the 120 mm square frame matches standard 120 mm mounting patterns, and the ball bearing does not change the hole spacing.

How can I confirm the fan is delivering its rated airflow after installation?

Measure the air volume at the outlet; the spec lists 84 CFM at the lower speed and 120 CFM at the higher speed.
