PE sintered porous filter element oxygen generator silencing filter element Raw Material UHMW-PE ,HDPE, PP Application Air source silencing ,vocuum filtration Product feature 1. Polymer properties of ventilation and water resistance could filter water and air pollution in the compressed air, ensure the purity of the pneumatic compression of air. It replaces the traditional sintered metal, improves the quality of filtration and reduces the cost. 2.In pneumatic system by change valve ,the compressed air supply to cylinder actuators, after action is finished ,then the compressed air discharge to atmosphere by change valve . Rapid expansion of compressed air and presure changes will produce high-frequency dissonant noise .With muffler to reduce exhaust noise can drop noise about 20-40dB. Polymer microporous filter chip is within the muffler , large ventilation and low noise . It replaces the traditional sintered metal and reduces the cost.
