Main features:

1. Using special muffler material, make it through the pipe sound absorption, noise reduction 15-- 20dB .

2. Simple installation, generally equipped at the air outlet, but if necessary, can be installed at the air inlet, the effect is better.

3. All the above are standard all-air fans, which can be installed with one mouth! But because of different brand fan tuyere size is different, our company can be customized according to the actual non-standard.

High pressure fan muffler fan noise suppressor impedance type muffler noise reduction principle:

This kind of muffler is by means of the sudden expansion (or contraction) of the pipeline section or adjacent to the resonance cavity, or in the pipeline wall attached to the special muffler material quality, so that along the pipeline transmission of some frequency of the sound wave in the mutation to the direction of the sound source reflected back, so as to achieve the purpose of muffler.
