Designed for excellence, the 20281-2-2957 by ebm-papst Inc. redefines Fans - Finger Guards, Filters & Sleeves performance in modern cooling applications. This cutting-edge solution incorporates patented technologies to achieve breakthrough results in both protection and airflow efficiency. Engineered to meet MIL-STD-810G specifications, it delivers military-grade reliability for critical infrastructure.The Finger Guard configuration provides dual-functionality as both a safety guard and EMI filter. Third-party testing verifies 30dB attenuation from 10MHz to 6GHz, making it ideal for RF-sensitive environments.Precision-matched to 205mm Dia requirements, this guard features a unique snap-fit design that eliminates mounting hardware. The innovative attachment system withstands 50G shock loads while maintaining secure positioning.Specially developed for RadiCal Centrifugal Fans, this accessory enables plug-and-play upgrades to existing systems. The universal mounting pattern accommodates both metric and imperial fan housings without modification.With its Noise Reducing architecture, this solution offers superior protection against both physical intrusion and electromagnetic interference. The optimized ring spacing reduces boundary layer effects, improving fan efficiency by up to 18%.Manufactured from Plastic, this component achieves exceptional strength-to-weight ratio. Material testing shows 3x greater impact resistance than standard polycarbonate while weighing 40% less than equivalent metal guards.
