2218F/2TDH4OU ebmpapst 48V 2.65A 127W 220mm DC Axial Fan

Description

The ebmpapst 2218F/2TDH4OU is a high-performance 48 V industrial axial fan with dimensions of 220 x 200 x 51 mm, meticulously engineered for critical thermal management in high-impedance environments. This unit integrates a high-torque brushless DC motor optimized for a 127.0 W power envelope, driving a specialized 5-blade impeller to a peak velocity of 7000 RPM. Designed to overcome extreme system backpressure, it generates exceptional airflow and static pressure, ensuring consistent laminar cooling through densely packed electronics. The mechanical foundation consists of a precision-balanced dual ball bearing system and a die-cast aluminum housing, providing 70,000 hours of reliable service even at a 40 °C ambient temperature. Featuring a robust 4-wire interface for advanced speed control and a certified IP68 rating for extreme environmental resistance, this fan is an essential component for IT/Telecom infrastructure, industrial inverters, and high-performance alternative energy systems where maximum air density and aerodynamic efficiency are mandatory.
