Silencer is a device that prevents sound from passing and allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. The silencer is a noise-reducing device mounted on an air flow channel (such as a blower, air compressor) or in an inlet and exhaust system. silencer can block the propagation of sound waves, allowing air flow through, is an effective tool to control noise.
Effect : reduce noise 5~10db.
