MGT7012HR-O25C Protechnic 12V 0.22A 70x70x25mm DC Axial Fan

Description

Protechnic MGT7012HR-O25C is a 70 x 70 x 25 mm DC axial fan featuring a 12 VDC operating voltage, 0.22 A current consumption, and 4200 RPM rotational speed. The unit is constructed with a glass-fiber reinforced PBT plastic frame and impeller, both rated to UL 94V-0 flame retardancy standards. It utilizes the proprietary Magic Bearing system, a specialized hydraulic mechanism designed for reduced friction and extended operational life. The internal motor is a brushless DC design with auto-restart and polarity protection, delivering a maximum airflow of 32.5 CFM and a static pressure of 4.8 mmH2O. The electrical interface is provided via a 3-wire lead configuration, including a dedicated tachometer (FG) signal for real-time monitoring of the fan’s rotational frequency.
