MGA0424HB-O20 Protechnic 24V 0.11A 40mm 4020 DC Axial Fan

Description

The Protechnic MGA0424HB-O20 is a high-speed compact 24V DC Axial Fan with dimensions of 40 x 40 x 20 mm, designed for precision thermal management in space-constrained electronic applications. Operating at a nominal 24 VDC, this unit reaches a rated speed of 8200 RPM, delivering an airflow of 18.4 m3/h (10.8 CFM) with a power consumption of 2.64 W. Built with a high-precision dual ball bearing system for enhanced reliability, the fan utilizes a 5-blade glass-fiber reinforced PBT impeller to maintain structural stability at high rotational speeds. The MGA0424HB-O20 is an essential cooling solution for 1U server components, network switches, and medical instrumentation where high static pressure and compact airflow are required to overcome high system impedance.
