Primary Advantage: Noise Reduction

ebm-papst has achieved significant noise reduction with the new 420J design. This reduction is 5dB lower than the 414JHH, which represents an easily audible noise reduction. They have accomplished this through new aerodynamics, a sturdy attachment to the housing and a noise-optimized streamer device, among other factors.
