8300100443 VWCE040KHDGS ebmpapst 12V 40mm 4028 DC Axial Fan

Description

The ebmpapst 8300100443 VWCE040KHDGS is a professional-grade, high-velocity DC Axial Fan designed for mission-critical cooling in high-density environments like 1U servers and network switches. Operating on a nominal 12 VDC supply (8.0 – 13.8 VDC range), this unit is powered by a high-torque Brushless DC Motor that drives a 5-blade impeller to an extraordinary speed of 27000 RPM. Within its high-performance 40 x 40 x 28 mm footprint, it delivers a massive air flow of 56 m³/h (33 CFM) and generates significant static pressure to overcome internal system resistance. Featuring a 4-wire interface for precise PWM speed control and Tacho signal feedback, the VWCE040KHDGS provides an intelligent and robust thermal management solution with IP20 protection and dual ball bearings for 24/7 industrial reliability.
