PMD2409PMB1-A.(2).F.GN Sunon 24V 12.2W 92mm DC Axial Fan

Description

The Sunon PMD2409PMB1-A.(2).F.GN 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 massive 12.2 W power output to drive its specialized 7-blade impeller at a consistent 4900 RPM. Engineered specifically to combat extreme backpressure, it generates a formidable 0.71 inH₂O static pressure, making it an ideal solution for pushing air through densely obstructed heatsinks and narrow chassis. The mechanical design relies on a precision-shielded dual ball bearing system and a fiberglass-reinforced PBT housing to ensure 70,000 hours of continuous operation at a 40 °C ambient temperature. Equipped with a standard 3-wire FG tachometer for real-time speed monitoring, this fan is a critical component for high-density blade servers, telecom rectifiers, and high-wattage industrial power supplies where maximum air density and reliability are non-negotiable.
