MGA12012UB-O38 Protechnic 12V 2.20A 120mm DC Axial Fan

Description

The Protechnic MGA12012UB-O38 is a high-performance DC Axial Fan with dimensions of 120 x 120 x 38 mm. Operating at a nominal voltage of 12 V (5.0 V to 13.8 V range), this ultra-high-speed cooling fan is engineered by Protechnic Electric to deliver exceptional airflow of 192.90 CFM (approx. 327.7 m³/h). Featuring a dual ball bearing system and a reinforced PBT frame, it is designed for heavy-duty industrial cooling. This model is specifically optimized for high-resistance environments such as server racks, industrial telecommunications, and high-power workstations where maximum static pressure and reliability are mandatory for critical heat dissipation.
