4715KL-05W-B30-P00 NMB 24V 0.40A 120mm DC Axial Fan

Description

The NMB 4715KL-05W-B30-P00 is a high-performance 24 V industrial axial fan with dimensions of 120 x 120 x 38 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty brushless DC motor capable of sustaining a 9.6 W power input to drive its specialized 7-blade impeller at a consistent 3300 RPM. Engineered specifically for high-torque air displacement in mission-critical hardware, it utilizes a robust fiberglass-reinforced PBT structure to ensure consistent heat dissipation under heavy thermal loads. The mechanical design relies on a precision-shielded dual ball bearing system to ensure 50,000 hours of continuous operation at a 25 °C ambient temperature. Featuring a simplified 2-wire electrical interface for direct power connection, this fan is a critical component for industrial workstations, networking hubs, and power converters where long-term reliability and high-velocity cooling are mandatory.
