SXDOOL

SXDOOL FFB1424VHG 24V 140mm 50mm 3200RPM case fan

SKU CH-E28G-1YDGH MPN FFB1424VHG

A 140 mm by 50 mm case fan running at 3200 RPM delivers 252.11 CFM airflow and 0.644 in H₂O pressure with double ball bearings for long service life

  • High airflow of 252.11 CFM cools demanding chassis and servers
  • 3200 RPM at 24 V delivers strong static pressure of 0.644 in H₂O
  • Double ball bearings give maintenance-free operation and long service life
  • Actual current draw of 0.91 A reduces power load versus 1.37 A rating
  • 5 dBA noise level suits industrial and high-end computing environments

Industrial cooling fan

The Delta FFB1424VHG is a 140 mm by 50 mm case fan designed for 24 V systems in servers, inverters and industrial chassis. It delivers 252.11 CFM at 3200 RPM through a four-pin PWM interface for precise speed control.

Thermals and acoustics

At the rated 0.91 A draw the fan produces 0.644 in H₂O static pressure while emitting 58.5 dBA. Double ball bearings eliminate sleeve wear and keep noise stable over long service intervals.

Sustained load behaviour

The 1.37 A start-up surge settles to the lower operating current once the rotor reaches full speed, allowing continuous duty in high-restriction enclosures. Maintenance-free bearings support uninterrupted airflow in demanding 24 V environments.

Soalan tentang produk ini

How do I install the 140*140*50mm fan in a standard chassis and which step is often missed?

Mount the fan using the four corner holes with screws, orient the airflow arrow toward the exhaust side, and connect the 4-wire 4-pin plug to a 24V PWM header; the step most people miss is verifying the header supplies 24V rather than a lower voltage.

What maintenance or replacement will the double ball bearing assembly need over its service life?

The maintenance-free double ball bearings are sealed for long service life; no lubrication or bearing service is required, and replacement is only necessary if the fan fails or noise exceeds the rated 58.5DBA.

At what point does the 0.644IN H2O static pressure become the limiting factor during sustained high-load operation?

The 0.644IN H2O pressure limit is reached first when airflow must push through dense radiator fins or restrictive filters, capping the delivered 252.11CFM before the 3200RPM motor hits its thermal ceiling.
