Main Applications
Petrochemical: high-temperature and high-pressure media filtration
Pharmaceutical & Food: sterile and clarification filtration
Water treatment & Environmental: pre-filtration and gas dedusting
Aerospace & Hydraulics: precision oil and fluid filtration
Electronics & Semiconductors: high-purity gas and chemical filtration
Service Life
Under normal operating conditions, service life ranges from 1 to 5 years, depending on media properties, temperature, and cleaning frequency. Regular backwashing, ultrasonic cleaning, or chemical regeneration can significantly extend service intervals.
Resistant to extreme environments, it possesses extremely strong resistance to high temperatures, high pressures and chemical corrosion. Its operating temperature range is typically between -60℃ and 500℃. Some special alloy filter elements can even withstand temperatures as high as 700℃, with a maximum pressure difference of up to 2MPa. It has excellent physical properties, including excellent air permeability, large pollutant capacity, high mechanical strength and good sealing performance. It is environmentally friendly, economical, has a long service life, and can support cleaning and regeneration after clogging, allowing for repeated use, thereby reducing long-term operating costs.

FAQ
1. Can metal filter elements withstand high temperature and high pressure?
Yes. Depending on material, operating temperature can exceed 600°C, and pressure can reach dozens of MPa. They are suitable for steam sterilization and high-pressure systems.
2. What filtration accuracy can be achieved?
Typically 0.1–200μm, selectable. Precision is controlled by sintering process and pore size, covering coarse to fine filtration needs.
3. Do they shed particles and cause secondary contamination?
No. They are integrally sintered with no fiber or particle shedding, ensuring high cleanliness for purity-sensitive applications.
4. How are they cleaned and regenerated?
Backwashing, ultrasonic cleaning, or chemical dissolution can be used. Filtration performance can recover over 90% of initial level, with many reuse cycles.
5. How is corrosion resistance?
316L stainless steel resists most acids, alkalis, and solvents. For special media, Hastelloy or titanium is available. Material selection depends on the specific fluid.
