PFB1224UHE 120mm DC Axial Fan 24V 252.85 CFM 5500 RPM | Delta

The Original New Delta PFB1224UHE is a 120mm × 120mm × 38mm DC axial fan from the PFB series, engineered for high-performance thermal management in demanding industrial and IT applications. Delivering an airflow of 252.85 CFM (7.16 m³/min) at 5500 RPM with a static pressure of 1.412 in H₂O (351.7 Pa), it provides powerful cooling for servers, power supplies, telecom equipment, and industrial control panels. The fan features a durable ball bearing system rated for 70,000 hours at 40°C, a plastic impeller and frame (UL 94V-0 flame-retardant), and locked rotor protection. Operating on 24 V DC with 2-wire lead termination, it is a reliable, maintenance-free solution for continuous-duty thermal management.
