24 V Delta axial fan

The FFB1224SHE-BROOSize is a 120 mm square Delta axial fan built for 24 V DC systems. It draws a nominal 1.5 A and spins at 3600 RPM to deliver 170.62 CFM of airflow. The unit suits industrial enclosures, server chassis or custom cooling loops that require high static pressure in a 38 mm thick frame.

Practical limits of 24 V operation

Running at 24 V means the fan must be powered from a dedicated 24 V rail or an external supply; standard PC 12 V headers cannot drive it. The 19.2 W power rating and 0.8 A actual current draw set the minimum capacity any source must provide. Without a compatible 24 V circuit the fan will not start, so builders using typical ATX power supplies need a separate voltage solution.

Steel frame and mounting implications

The housing uses a sturdy steel plate external-rotor motor that resists vibration in continuous-duty environments. Four corner holes match standard 120 mm mounting patterns, allowing direct replacement of lower-spec fans in existing cut-outs. At 56.5 dBA the acoustic output is noticeable, so the fan is best placed in rack cabinets or noise-tolerant workspaces rather than quiet desktop builds.

Questions about this item

Should I choose the 24 V 1.5 A version or a lower-voltage model for my 24 V system?

The fan is rated for 24 V with a nominal current of 1.5 A, so it matches a 24 V supply directly.

What does 170.62 CFM mean for actual case airflow?

At 3600 RPM the fan delivers 170.62 CFM, moving a high volume of air through a 120×120×38 mm frame.

Does the 24 V DC input limit speed control options?

The unit runs on 24 V DC and supports 100 % speed control via analog or serial interface.
