GFM0412SS-01 Delta 12VDC 40x40x56mm Counter-Rotating Fan

Description

The Delta GFM0412SS-01 is a high-performance counter-rotating axial fan engineered for environments demanding exceptional static pressure and airflow density. Designed with a dual-rotor architecture within a compact 40x56mm frame, this unit utilizes contra-rotating impellers to straighten airflow trajectories, significantly reducing vortex losses and maximizing aerodynamic efficiency. The robust brushless DC motor assembly ensures structural rigidity and consistent operation under high-speed conditions, while the precision ball bearing system manages thermal impedance effectively. This configuration is specifically optimized to overcome high system resistance in dense electronic enclosures.
