8489-MO

The 8489-MO by Keystone Electronics pioneers next-generation Fans - Finger Guards, Filters & Sleeves technology for renewable energy applications. This innovative solution withstands extreme environmental conditions while maintaining optimal thermal performance. With its corrosion-resistant design, it delivers 10+ years of reliable service in solar and wind power installations.Functioning as a Replacement Filter Element, this component provides all-weather protection with IP69K certification. Testing validates continuous operation through 1000+ thermal cycles from -40 C to 85 C with zero performance degradation.Engineered for 120mm Sq requirements in outdoor applications, this guard features a unique self-cleaning surface that reduces maintenance frequency. The hydrophobic coating maintains 95% of original airflow after 5 years of exposure.Constructed from UV-stabilized Polyester (PES), this guard maintains mechanical properties after 15,000 hours of accelerated weathering. Material testing shows less than 5% tensile strength loss under extreme environmental stress.
