SILEO specifically conceives solutions to reduce air intake and repression noises of centrifugal compressors. This type of machines generates a noise whose spectrum is especially important in averages and high frequencies. SILEO absorbing silencers are designed to bring a maximum attenuation at these frequencies with minimal pressure loss for various applications: *axial and centrifugal Compressors, *screw compressors, *multi-stages blowers, *vacuum pumps, *ventilators.
