1. Accurate uniform pore sizes, evenly distributed filtration pores, range from 0.1um to 120 microns.
2. Large porosity, excellent breath ability, fast flow rate for gas and liquid, and it is far superior to other peer products with the optimization of special process in HENGKO.
3. Good filtration dustproof effect, high filtration efficiency; the pore size, flow rate, and many other features can be can accurately custom.
4. High supporting load capacity, no need to use other auxiliary supports, can be directly used as structural elements.  5. Structural stable, solid molecular tightly bound no migration, virtually inseparable, even under the harshest conditions.
6. High fatigue strength, high load shock stress resistance, high pressure resistance, well suited for high differential pressures and flow rates, the leading position in high pressure flow medium (40 MPa) sintered porous metal elements.    
7. High temperature resistance and heat shock tolerance, HENGKO stainless steel filters can even work normally at 600 degree; endure high temperatures, even in the midst of oxidizing atmospheres.   
8. With special multi-dimensional honeycomb nest capillary structure, the filters possess an excellent function of separation and noise reduction.     
9. Corrosion resistance, antirust.                               
10. More than 100 thousands of standard types and models available.
11. Size and structure can be customized as required.
12. The super slender structure microporous filter tubes, minimum outer diameter 5 mm× length 800 mm.
