- Pressure/Pressure Difference: Maximum operating pressure 30 MPa; maximum permissible pressure difference 3.0 MPa

- Connection: Standard 226/222 or M36×1.5 thread (V-type end cap)

- End Cap/Seal: 316L metal end cap, Viton (fluororubber) seal, oil/solvent resistant

 III. Key Performance Characteristics

1. High Temperature and High Pressure Resistance: Made of 316L material, capable of long-term stable operation under harsh conditions of 450℃, 30MPa.

2. High Dirt Holding Capacity and Long Lifespan: Folded + five-layer depth structure, large dirt holding capacity, lifespan approximately 4000–8000 hours.

3. Washable and Regenerable: Supports backwashing, ultrasonic cleaning, and chemical cleaning, with a flux recovery rate >90%, allowing for repeated use.

4. Corrosion Resistant and Fiber-Free: Integral sintering, no fiber shedding, resistant to acid, alkali, organic solvents, and water vapor corrosion.

5. Low Pressure Drop and High Flow Rate: High porosity, initial pressure drop ≤ 1.5 kPa (@rated flow rate).

 IV. Typical Applications

- Compressed Air/Industrial Gases: Removal of particles, oil mist, and water vapor (air compressors, nitrogen, carbon dioxide)

- High-Temperature Liquids/Meltes: Filtration of high-temperature viscous media in chemical, synthetic fiber, and polyester production

- Hydraulic/Lubrication Systems: Precision filtration in high-pressure pump stations, gearboxes, and servo systems

- Steam/High-Temperature Flue Gas: Purification of exhaust gas from power plants, steel mills, and boilers.
