The unique structure reduces noise that enters from outside through the ducts!

This is a duct silencer that can significantly reduce noise transmitted indoors through ducts from range hoods in multi-family housing located in areas with high external noise (such as railways and roads). It is effective across a wide frequency range from low to high frequencies. Despite having high sound reduction performance, it features a compact size structure, allowing for effective use of the available space within the ceiling. Additionally, it can minimize pressure loss to the utmost extent, ensuring the maintenance of range airflow.
