Silencing louvers have the function of blocking noise from entering the surrounding environment and fully circulating air at the same time. According to the formation of sound absorption sheet, it can be divided into: a. Folded plate sound absorber - zbb1 b. Elliptical wing sound absorber - tyb2

·AXB1 folded plate sound-absorbing sheet louver

Hot dip galvanized steel plate or stainless steel shall be used. Its sound absorption is a folded plate resistive sound absorption sheet, which has great sound absorption area and strong noise attenuation ability. It can be installed in masonry or other building structures in a flat embedded manner, or it can be used as an independent barrier wall.

·Brief Introduction

The silencing elbow is similar to the pipe muffler, which is also one of the impedance mufflers. It is a muffler that changes the straight pipe muffler into an elbow muffler.

·Structure

The inner wall of the silencing chamber is filled with 50mm thick centrifugal glass wool, covered with glass cloth and 3mm aperture perforated plate, and the keel is galvanized plate. Main technical parameters: silencing volume: 7dB (a) Resistance loss: 2.5mmh, O (when the wind speed is 6m / s)

·Brief Introduction

Impedance muffler combines the advantages of resistive muffler and resistance muffler. It improves the performance of low, medium and high frequency muffler to a certain extent.

·Structure

The inner wall of the muffler is filled with centrifugal glass wool, covered with glass cloth and 3mm perforated plate. The keel is galvanized plate, or medium 0.8mm micro perforated plate can be used. Main technical parameters: Silencing volume: rated air volume: The low frequency silencing amount is 10-15db (a), the medium frequency silencing amount is 15-25DB (a), and the high frequency silencing amount is 10-15db (a) Applicable air volume: 2000m3 / h-60000m3 / h (wind speed should be 6-8m / s) resistance loss: the average resistance coefficient is 0.4 at rated air volume

·Brief Introduction

The resistive muffler uses the porous sound-absorbing material laid in the air flow channel to absorb sound energy and reduce the noise transmitted along the channel. It has good medium and high frequency silencing performance.

·Brief Introduction

Pipe muffler is a kind of impedance muffler. It has the characteristics of small volume and simple form, so it has a wide range of applications.

·Structure

The inner wall of the anechoic chamber is filled with centrifugal glass wool, covered with glass cloth and medium 3mm porous plate. The thickness of air deflector is 100mm.

·Main technical parameters

Silencing amount: 18.5db (a) Resistance loss: 2mmh, O (when the wind speed is 6m / s)

·Brief Introduction

The silencing static pressure box is generally installed at the outlet (return) of the fan or air-conditioning air cabinet. The static pressure box is pasted with sound-absorbing materials, which can not only stabilize the air flow, but also effectively attenuate the noise of the fan or air-conditioning air cabinet by using the sudden change of the box section and the sound absorption effect of the surface inside the box.

·Structure

The inner wall of the silencing chamber is filled with 50mm thick centrifugal glass wool, covered with glass cloth and 3mm medium aperture perforated plate, and the keel is galvanized plate.
