The nuclear industry filter called "nuclear grade filter".
In order to prevent radioactive dust scattered into the air, the plant's exhaust system needs a large number of highly efficient filter.This kind of high efficient filter efficiency for: 0.3 mm DOP particle filtration efficiency of 99.97%.
Most efficient filter used in nuclear power plants is a traditional form of separator filter, among them, the filter material is glass fiber filter paper, partition using 0.038 mm aluminum foil, frame is carbon steel or stainless steel material, between the casing outside the filter paper and adhesive for silicone, PVC or other heat-resistant material, filter the windward and leeward side of a metal fence.Many performance in nuclear grade filter belong to "performance" excess at ordinary times, the performance is for the reliability of the accident when considering.
