Delta Electronics PFB1224UHE is a high-performance 24 VDC brushless tubeaxial fan for forced-air cooling in cabinets, power electronics and other equipment with high airflow and static-pressure requirements.
The 120 x 120 x 38 mm fan is rated at 5500 rpm and delivers 252.9 CFM airflow with 351.7 Pa static pressure. Its two-wire connection uses red for positive and black for negative, while a locked-rotor current-shutdown function protects the fan under a stalled condition.
For replacement, verify the complete PFB1224UHE model, 24 VDC supply range, 48 W power budget, connector or lead termination, airflow direction, mounting-hole pattern, guard clearance and system noise requirement.
