The application concept of using a fail safety filter on the filtering system is to prevent the particle leakage when the main filter element is broken at high temperature. In this study, the metal filters were fabricated by pressureless sintering method. The mixture of stainless steel powders and filler metal binder solved in the water solutions of 5% PVA was compacted to form the cylindrical filter without pressure. The compacted filter were sintered in the vacuum sintering furnace at 120 for 1 hour. The metal filter(produced with powder of 640-840 size) having more than above 50% porosity, 500 pore size, and permeability of 7.310m plugged within 2.5 minute to prevent the leakage of maximum slip particle size of less than 3.
