3615RL-05W-B30-EQ3 NMB 24V 0.53A 92mm DC Axial Fan

Description

The NMB 3615RL-05W-B30-EQ3 is a high-performance 24 V industrial axial fan with dimensions of 92 x 92 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 12.72 W power input to drive its specialized 7-blade impeller at a consistent 3150 RPM. Engineered specifically for high-torque air displacement in mission-critical hardware, it utilizes a 38 mm deep housing to overcome massive backpressure in densely packed enclosures. The mechanical design relies on a precision-shielded dual ball bearing system and a fiberglass-reinforced PBT housing 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 power supplies, telecommunications racks, and medical diagnostic equipment where long-term reliability and high-velocity cooling are mandatory.
