GR1 Titanium Powder Sintered Filter plate (including tube type and plate type) is a micro filter

element made of sponge titanium powder as raw material, after sieving, molding, and high-

temperature vacuum sintering. It has the characteristics of high filtration precision, good air

permeability, high mechanical strength, and high material utilization rate, suitable for higher working

temperatures and thermal shock. Widely used in pneumatic components, the chemical industry,

environmental protection, and other fields.

It can produce porous elements of various shapes, structures, different particle sizes, and porosity

according to user requirements, such as cover, cap, sheet, tube, and rod-shaped filter elements. The

high-temperature titanium powder sintered filter material has unique and excellent properties due to

its high-tech material composition and special molding process:

Filtration accuracy	Porosity	Permeability	Compressive strength	Temperature resistance	Maximum working pressure
0.22-100um	30-50％	3-1300m³/m³hkPa	3Mpa	280℃	0.6Mpa

Precautions for use

1. The superalloy powder sintered filter element is a consumable item. Although it is more durable than other filter elements, care should be taken not to scratch, touch, smash, or drop during the cleaning and disassembly process to prevent man-made damage. It is strictly forbidden to use tools to apply force to the surface of the filter element.

2. Under normal circumstances, the filtrate is filtered from the outside to the inside of the filter element, and reverse filtration is not recommended.

3. When filtering, slowly pressurize to the required working pressure, and it is strictly forbidden to open the valve to quickly pressurize.

4. When the maximum working pressure is less than or equal to 3MPa, and the filtration efficiency is lower than 50%, it is necessary to use clean air or clean liquid to backflush online in time.

5. When performing backflushing and backflushing of the superalloy powder sintered filter element, generally use pure gas to backflush first. The backflushing pressure is 1.2-1.5 times the working pressure. The backflushing time is 3-5 seconds each time, and the operation is repeated 4- After 6 times, backwash with cleaning solution, and backwash for 3-5 minutes, 2-3 times.

6. If the pressure loss of the filter element is still serious after the online backflushing and backwashing, it should be removed in time for cleaning.

Precautions for the use of titanium-sintered porous materials:

During installation, disassembly, and cleaning avoid scratches, collisions, and falls on hard objects.
1. When used, the filtrate is filtered from the outside to avoid the reverse direction.
Avoid instant pressurization when the filter element works.
1. When the filtration efficiency is less than 50%, the filter element should be cleaned in time.
2. When cleaning the filter element, the first backflow with pure gas, backflow pressure is 1.5 times the working pressure, each time for 3-5 seconds, and 4-6 times, then backwash with clean liquid for 3-5 minutes, repeat 2-3 times.
If the filter element is not good after online back blowing and backwashing, it should be removed and cleaned in time.
