Overview of microporous plate muffler

The micro perforated plate muffler is a double cavity structure with wide absorption frequency band. It has flat and large silencing amount for each frequency band. Especially for the low-frequency part, it has obvious silencing effect, which is better than the impedance composite muffler with fibrous sound-absorbing material structure.

The diameter of connecting pipe flange of this series of muffler constitutes a corresponding supporting series according to the national general ventilation pipe specifications (square, rectangular and circular). The effective length is generally 2000mm. It can also be produced according to the requirements of users. According to the requirements of silencing volume, several sections can be connected in series in the middle. The flow rate of muffler is generally ≤ 15m / s.
