Fans AFB0948MSize 9 cm 48V 2.4 W 37 CFM 2100 RPM 25 dB-A ball bearing case fan

SKU CH-KR22-DP77E MPN AFB0948MSize

A 9 cm 48 V ball-bearing case fan moves 37 CFM at 2100 RPM with 25 dB-A noise

  • Quiet operation at 25 dB-A noise level
  • Efficient cooling with 37 CFM airflow
  • Reliable 48 V ball-bearing motor
  • Compact 90 mm square frame fits tight spaces
  • Low 2.4 W power draw saves energy

9 cm 48V ball-bearing case fan

The AFB0948MSize is a 90 mm axial fan built for 48 V DC systems. It draws 0.08 A and consumes 2.4 W while spinning at 2100 RPM. The ball bearing supports continuous operation in industrial and embedded environments.

Suited for tight 48 V cooling slots.

This fan fits equipment that supplies 48 V directly, such as telecom, medical, rail or industrial enclosures. It delivers 37 CFM at 25 dB-A in a 90x90x25 mm frame. Builders using standard PC 12 V headers or needing higher static pressure for dense radiators should look elsewhere.

48 V 0.08 A power input decides compatibility

The single specification that determines fit is the 48 V 0.08 A electrical rating. Only systems providing that exact voltage and current can run the fan correctly. No adapter or converter is included, so verify the power source before purchase.

Questions about this item

How do I mount the 90*90*25mm AFB0948M fan in a standard case and what step is often missed?

Align the four 90 mm corner holes with your chassis fan mounts, use the supplied screws, and connect the two-wire 48 V lead to a compatible header; the step most people miss is verifying the header supplies 48 V rather than 12 V.

What maintenance will the ball-bearing AFB0948M need after long-term operation?

The sealed ball bearing is rated for continuous duty and requires no lubrication; if noise rises above the specified 25 dB-A or speed drops below 2100 RPM, replace the entire fan unit.

At what point does the 2.4 W AFB0948M hit its thermal limit during sustained load?

The fan is designed for continuous operation at 48 V and 0.08 A; the first limit encountered under sustained use is the maximum airflow of 37 CFM, beyond which additional cooling must come from extra fans or a larger heatsink.
