1. High porosity and uniform airflow distribution.

2. High strength: After the multi-layer screen is sintered, it has high mechanical strength and compressive strength.

3. Simple cleaning: Due to the excellent surface cleaning structure of the whitewater cleaning effect, the countercurrent cleaning effect is good, can be used repeatedly, and has a long service life (cleaning by means of reverse water, filtrate, ultrasonic, dissolution, baking, etc.).

4. It can eliminate faults such as breakdown short circuit and blockage, and has a long service life.

5. Mass transfer heat transfer and flow too good effect, high efficiency, low gas consumption.

6. It can flow in a gradient less than the quiet angle, and some powders can flow in an inverse gradient.

7. It is easy to process, form and weld well; it has large operation flexibility and convenient process adjustment.

8. High temperature resistance, corrosion resistance, high precision: It can withstand high temperature and low temperature from -200 ° C ~ 480 ° C and acid and alkali environment filtration, and can achieve stable surface filtration performance for filtration accuracy of 1~500um.
