GRM120-45

The GRM120-45 by Orion Fans 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 Filter Guard Assembly, 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.When paired with OA109, OA125, OA4715, OD1225, OD1238 Series, this system creates a complete environmentally-hardened thermal solution. The galvanically-isolated mounting system prevents corrosion in coastal installations.With its Self Extinguishing design, this solution incorporates lightning protection up to 10kA. The integrated surge protection circuitry prevents damage from electrical transients common in renewable energy systems.Constructed from UV-stabilized Acrylonitrile Butadiene Styrene (ABS), Polyurethane Foam, 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.
