The copper filter element is sintered with copper powder. It has good permeation filtration performance and high filtration precision, can better withstand thermal pressure and impact, high strength, good plasticity, oxidation resistance and corrosion resistance. Good assembly, can be welded, bonded and machined; strong regeneration ability, long service life; various porosity (28%-50%), pore size (4u-160U) and filtration accuracy (0.2um-100um) ), the channels are criss-crossed, can be used at a high temperature of 300, resistant to rapid cooling and rapid heating. Compared with filters made of paper, copper wire mesh and other fiber cloths, the performance is superior, and the assembly and disassembly cleaning is convenient. It is mainly used to filter gas, liquid, and fuel oil. It is widely used in the above, and is also widely used in the filter elements of pneumatic and hydraulic circuits. The copper powder sintered filter cartridge can filter oil, water and impurities in the air, and can also reduce noise. In the compressed air self-rescue device, its air supply generally adopts the mine compressed air pipeline, which can decompress, muffle, adjust the flow, filter oil and water and other functions of the compressed air, so as to provide fresh air for the staff. The copper sintered filter element has the functions of air filtration and noise reduction, and is widely used in the air source processor of pneumatic components.

Technical FeaturesEdit

1. The filtration precision is high, the pores are stable, and the phenomenon that the pore size changes with the pressure change does not occur. It can effectively remove suspended solids and particles, etc., with excellent filtration accuracy and good purification effect.

2. Good air permeability and low pressure loss. The filter element is completely composed of spherical powder, with high porosity, uniform and smooth pore size, small initial resistance, easy backflushing, strong regeneration ability and long service life.

3. High mechanical strength, good rigidity, good plasticity, oxidation resistance, corrosion resistance, no need for external skeleton support protection, simple installation and use, convenient maintenance, good assembly, and can be welded, bonded and machined.

4. Pores are uniform, especially suitable for occasions with high requirements for uniformity such as fluid distribution and homogenization.

5. Copper powder sintered products can be formed at one time without cutting, the effective utilization rate of raw materials is high, and materials are saved to the greatest extent, especially suitable for components with large batches and complex structures.
