1. It is in fact a kind of resonance muffler, with all-metal dual-chamber type structure, using micro orifice plate as sound-absorbing components. Effective for silence frequency bandwidth (especial for low frequency) because of small aperture, low aperture ratio, large cavity and acoustic resistance.
2. It uses double layer micro orifice plate with different punching rate, composes two cavity with different thickness, stagger the resonance frequency of two-layer to get better effective in silence frequency bandwidth.
3. It has feature of bearable the impact of high temperature airflow, damp-proof, fireproof, anti-corrosive and no dust during work. Applicable for the ventilating duct with cleanliness requirements.
4. Unit section length is 2m, airflow velocity <16m/s, resistance loss is small and resistance valueζ≤0.4, silencer volume: low frequency 12~25dB, intermediate frequency 25~30dB.
5. Except XWK-I, there is sound-absorbing baffles in the channel of model II, III, IV which can improve the effective of silencing. Its length is 2m.
1. Chip-type Dissipative Muffler is that the Tube-type Resistive Muffler adds some sound-absorbing slice. It is applicable to large cross section of duct and large air flow. It divides the straight tube into several small channels, and sound-absorbing slice is straight type, ...
1. It is deformation from slice-type resistive muffler. In order to improve the noise elimination performance of high frequency, it is changed into folded plate type from straight slice type to get high sound attenuation with smaller section. It is suitable airflow velocity of ...
