Description
The Delta FFB1224EH-AR04 is a high-performance industrial axial fan engineered for extreme thermal management. Operating at a rated 24VDC with a robust 1.50A current draw, this 120x38mm unit delivers a massive airflow of 150.33 CFM and a static pressure of 0.489 inH2O. Equipped with a precision dual ball bearing system and a 3-wire configuration featuring a Lock Rotor Sensor (R04), it ensures long-term reliability (70,000 hours) and safety in high-density electronic environments. The glass-fiber reinforced plastic construction (UL 94V-0) provides structural integrity under high-speed 4000 RPM operation while maintaining a noise profile of 56.4 dB(A).
