The main material of stainless steel folding filter is made of 304, 304L, 316, 316L stainless steel fiber sintered felt and stainless steel woven mesh. The stainless steel fiber sintered felt is a porous depth filter made of stainless steel fiber sintered at high temperature.
Material; stainless steel woven mesh is made of stainless steel wire. The sealing faces of the filter core are joined by argon arc welding process. The filter layer adopts multi-fold folding process to form a complete filter element, no leakage, no medium falling off, and large filtering area. High filtration efficiency.

Performance judgment method:
Judging the performance of a stainless steel fiber felt folding filter containes the first bubble point, differential pressure flow characteristics, accuracy and dirt volume, strength, fluid pressure strength, axial load strength are considered.
The pressure value of the first bubble point of the filter element should not be lower than 90% of the pressure value of the first bubble point of the filter medium.
Pressure difference flow characteristics, when the oil temperature is around 30 °C, the rated pressure difference is 0.15Mpa, when the fluid is the standard state air, the rated pressure difference should be 200Pa
Accuracy is the most important standard for a stainless steel folding filter. It determines whether it can achieve its purpose. When ensuring that the filter structure is sufficiently complete, the accuracy depends on the accuracy of the filter.
The amount of pollutants refers to the amount of pollutants contained. The filter can intercept the pollutants, but it cannot be removed directly from the system. The pollutants can only remain inside the filter. The pollutant capacity of the filter is equal to the amount of pollutants per unit area and the filtration area. The product of the product, which is related to the differential pressure of the actual use of the filter element.
The strength is judged by fluid pressure strength, axial load strength and fatigue strength. Fluid pressure strength refers to the maximum pressure drop of a fluid that can withstand operation at work, usually no greater than the internal leak test pressure. Axial load strength refers to the force that can be accepted by normal assembly and disassembly without deforming the filter element. The fatigue strength refers to the fatigue fatigue of the filter element subjected to impact, vibration, flow pulse, etc. during operation. The strength is mainly ensured by the skeleton of the stainless steel folding filter. The simple folding filter itself has almost no strength, and generally requires the stainless steel skeleton to support the strength. When the filter element with sufficient strength is used, it can ensure no deformation, no damage, and no filter material falling off.
It is also because of the characteristics of the stainless steel folding filter as described above, it is widely used in environmental protection, petroleum, chemical, medical, high temperature gas filtration, scientific research, metallurgy, food, machinery and other industries.
