Micro-perforated plate muffler: ● for ventilation systems, and ventilation pipe through the flange connecting directly to facilitate the installation; ● through rigorous calculation of the acoustic and aerodynamic, with minimum ventilation resistance and regeneration of noise to achieve precise control of noise; ● do not fill in any sound-absorbing padding, you can request any of the cleanliness of the ventilation system in use; ● production of materials can be installed for different conditions, and so requires a flexible choice; ● According to the sound source characteristics, installation conditions, noise reduction requirements, the resistance of the different requirements and other factors can provide other models for choice;
