78128-2-4039

The 78128-2-4039 from ebm-papst Inc. sets new standards in Fans - Finger Guards, Filters & Sleeves innovation, combining advanced materials science with precision engineering. This thermally optimized solution delivers unmatched performance in high-density electronic cooling applications. With its patented airflow technology, it reduces system operating temperatures by up to 12 C compared to conventional designs.Functioning as a Finger Guard, this component provides three-tier protection: physical barrier, EMI shielding, and airflow conditioning. Independent testing confirms compliance with IEC 60529 IP55 standards for dust and water protection.Engineered for 225mm Sq applications, this guard features a unique aerodynamic profile that reduces system noise by 6dBA. The computational fluid dynamics (CFD) optimized design minimizes pressure drop across the guard surface.When integrated with W1G200, W2E200 Series, this solution creates a complete thermal management system. The modular design allows for stackable configurations, enabling customized solutions for high-power applications.The 10 Rings design incorporates advanced thermal management properties. Infrared thermography shows 25% more uniform heat distribution compared to standard finger guards, preventing hot spot formation.Utilizing Metal technology, this guard offers exceptional chemical resistance. Accelerated aging tests demonstrate 10+ years of service life when exposed to industrial atmospheres containing sulfur compounds.
