This type of muffler has a dual cavity structure, and its absorption bandwidth can reach more than 10 1/3 octave bands. It has a relatively flat and large noise reduction for each frequency band. The noise reduction is 12-25dB at low frequencies and 20-25dB at medium to high frequencies (with a length of 2000mm and wind speed of 10-15m/s). According to the requirements of noise reduction, several sections can be connected in series in the middle, and the wind speed is generally controlled within 15m/s. It is suitable for use in ventilation ducts with moisture-proof, high temperature resistant, and clean requirements. If the user has special requirements, our company can design and manufacture it on behalf of them, and also undertake the design and processing according to the drawings.
This type of muffler interface flange is made according to the national standard air duct, and is divided into four types according to its size: QD-SW-I, QD-SW-II, QD-SW-II, and QD-SW-IV. The specific form is shown in the following figure.
