Lightweight Plastic Pneumatic Silencer for Noise Reduction - China Suppliers & Factory Direct Supply
Main Advantage
The main forms of vent exhaust mufflers are anti-spray compound muffler and small hole muffler. And has the following advantages:
-
1
It adopts all-steel reinforced structure, which can withstand long-term discharge under high pressure without changing its shape.
-
2
The multi-layer structure can adapt to the concentrated noise reduction of high, medium and low frequencies and can meet the requirements of high flow rate noise reduction.
-
3
The separate drainage structure of the muffler can meet the requirement that the pipe does not collect water, and at the same time, it can also absorb the vertical and horizontal thermal displacement of the exhaust pipe to ensure the hot state of the exhaust pipe.
When the user installs it according to the requirements, the total noise reduction can reach 30~42 decibels. The noise reduction effect meets the requirements of the "Industrial Enterprise Noise Hygienic Standard".
