66309-2-4039

The 66309-2-4039 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 Grill Guard - Basket, 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 172mm Dia 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 M4Q Series, this solution creates a complete thermal management system. The modular design allows for stackable configurations, enabling customized solutions for high-power applications.The 9 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.
