Blast furnace blower fan inlet and outlet gas silencer

High pressure centrifugal blower and axial flow fan are widely applied mechanical equipments with huge noise. Actually sound level could be 100~120dBA which cause severe noise pollution. After checking, when high pressure blower is running, its air dynamic characteristics noise is 10~20dBA higher than that of mechanical noise. Therefore, it is necessary to install filter to diminish its air dynamic characteristic noise.
Our company is the qualified complementary company for Xian Shangu Dynamic Share Com., Ltd. The producing process is strictly according to Shangu Standards, which ensure that each qualified silencer can be used without worry.
This type of silencer has two kinds: inlet silencer and discharge silencer. Suitable air flow from 500 to 21000 m 3 /min and noise reduced from 30~50dBA.
All silencers are matched with flange and fixing. When assemble on site, first welding counter flange and pipeline then fasten bolts; when assembly vent silencer, only need connect through bolt silencer bearing and bracket on site.
