Microperforated plate muffler is a muffler with a lined microperforated plate structure. It can eliminate airflow noise over a wide frequency range and has high temperature resistance, oil resistance, and corrosion resistance. Even if there is a large amount of moisture in the airflow, it does not affect the work. Due to the small perforation diameter and smooth surface, the resistance loss of the muffler is smaller than that of a general resistive muffler.

Microplate silencers are commonly used in blower exhaust, air conditioning systems, gas turbine exhaust, aircraft engine test room exhaust, intake ducts for jet engines, internal combustion engine intake and exhaust, etc.
