Industrial 24 V 120 mm fan

The Delta PFB1224UHE is a 120 mm by 38 mm axial fan built for 24 V DC systems. It draws 2.40 A at start-up and settles at 2.0 A during continuous operation. The unit targets integrators who need high static pressure in rack-mount, telecom or industrial enclosures.

Original Delta construction

The fan uses Delta’s original factory tooling and bears the supplier’s quality-assurance stamp. Its 48 W motor spins at 5500 RPM to push 252.85 CFM through dense heatsink arrays or restrictive filter panels. A 66.5 dBA noise rating reflects the airflow density required in server-grade environments.

24 V 2.40 A power envelope

The 24 V rail and 2.40 A peak current define the only compatible power budget; a 12 V supply or a header limited to 1 A will not start the motor. Verify that your chassis controller or external PSU can deliver the full 48 W before installation.
