Overview
___ __br The muffler is an effective device for controlling the outward propagation of aerodynamic noise. After internal acoustic treatment, it can greatly reduce the generation and propagation of noise without affecting the airflow.
Types and Characteristics
The impedance composite silencer has the characteristics of a sound-absorbing frequency band for safety. Mainly used for silencing high-sound level but low-mid-frequency broadband noise.
The folded plate impedance muffler achieves higher sound attenuation effect with a smaller cross-section and has less resistance loss.
Circular cross resistive mufflers are mostly used in the inlet and outlet of high-pressure axial flow fans, and the thickness can be selected according to needs.
Tube-type mufflers are suitable for medium and low-pressure centrifugal fans in ventilation and air conditioning.
The micro-perforated plate muffler is a new type of metal structure broadband muffler device, assembled from galvanized micro-perforated plates. Due to the use of double-layer orifice plates with different perforation rates and different back cavities, it has good effects in a wide audio frequency range. The muffler has a simple structure, is dust-free during operation, and is not afraid of the impact of oil mist, water vapor, and high-temperature gases. It is widely used in air-conditioning ventilation ducts.
