Structure
This series silencer is a kind of impedance complex exhaust-type muffler for which the dissipation section is arranged with tube still channel and the reaction section with multiple chamber channel and cross-shape acoustic board, thus guaranteeing the silencer with wide frequency bandwidth response.
Application scope
This silencer is suitable to various high-pressure centrifugal fans (8-18 type, 9-27 type) to reduce the aerodynamic noises resulted from the inlet and outlet.
Two ends of SL-QX type is connected to pipe with flanges.
One end of SL-QH type is covered with a rain-proof cap. SL-QH type is only used in outdoor pipeline or closed room air inlet.

300 | SL-ZDL low-pressure centrifugal fan silencer
Structure
This series silencer is a kind of piece-type dissipative muffler with features of convenient replacement and maintenance. There are three types (A, B, C) optional with 1m, 1.5m, 2m, 2.5m and 3m lengths which are suitable to different baffling frequency property.
Application scope
This silencer is mainly used to match with low and medium pressure centrifugal fans such as 4-72, 4-73, 5-48,6-48 fans widely used in industrial and civil buildings. For applications of ventilation and air exchange of boiler fan, this silencer can be used to reduce inlet and outlet noises. In the scope of 1000~700000m3/h, the silencer features with pressure resistance <8000Pa, baffling noise >25dB(A).
Notes to application
1. The air rate between baffling plates should be equal to the air rate in the pipe. For the silencer used in the civil buildings, the air rate between baffling plates should be a constant V=3-10m/s but for silencer used in industrial buildings, the air rate between baffling plates should be a constant V=12~25m/s, no bigger than 30m/s.
2. Before and after the silencer, reducers should be applied. During ordering, pipe’s section size and flange size should be noted.
3. If a rain-proof cover is needed, notations shall be offered.

2. Suitable pressure: The up-flow pressure before the relief valve 0.2Mpa< P <3.0MPA;
3. Suitable temperature: <400oC;
Noise reduction:>30 dB(A).
Notices:
1. The silencer is provided with a pair of connecting flange in No.20 steel PN2.5 Hg G20592-97 and a pair of sewage pipe flange;
2. The customer shall prepare a sewage valve;
4. If the up-flow pressure before the relief valve p<2.5 , Mpa, a ф=0.50 (Diameter of the connecting pipe) throttle plate shall be erected before the silencer.
3. It is forbidden to make oil and water into the acoustic material;
4. During installation, the silencer body should be erected vertically without bearing any pulling force from its weight and other external force.
