The 304 Stainless Steel Sintered Mesh Filter Cartridge 30×57 is a compact, high-performance filtration element designed for precise liquid, gas, and vapor filtration in space‑constrained industrial systems. This cartridge is engineered from multi‑layer 304 stainless steel woven wire mesh that is laminated and vacuum‑sintered at high temperatures to form a rigid, uniform porous structure.
The five‑layer design—comprising protection, filtration control, dispersion, and reinforcement layers—delivers consistent filtration accuracy from 1 to 200 microns, while offering exceptional mechanical strength, thermal stability (‑200°C to 600°C), and resistance to corrosion from acids, alkalis, and solvents.

The 304 stainless steel sintered mesh filter element is widely used across multiple demanding industries:
Petrochemical & Chemical Processing: High-temperature corrosive liquid filtration, catalyst recovery, chemical intermediate filtration, polymer filtration
Hydraulic & Lubrication Systems: Precision filtration of hydraulic oil and lubricating oil in industrial machinery
Pharmaceutical & Biotechnology: Sterile filtration of process gases, fermentation air, and high-purity liquid streams
Power Generation: High-temperature flue gas filtration and purification, turbine protection
Oil & Gas: Natural gas pipeline systems, refinery process filtration
Water Treatment: Industrial cooling water systems, RO pretreatment
Compressed Air & Pneumatic Systems: Particulate removal from compressed air lines, gas analyzers, sensor protection
Q1: Is this filter element suitable for high-pressure applications?
A1: Yes. The sintered metal construction provides high mechanical strength and pressure resistance. The element can withstand operating pressures up to 35 MPa (depending on configuration), making it suitable for high-pressure hydraulic and process applications.
Q2: What is the best method to clean this filter, and how do I know it’s clean?
A2: For most applications, ultrasonic cleaning followed by a clean water or solvent rinse is highly effective for removing embedded particles. Backflushing with clean compressed air or liquid is also common. A well-cleaned filter will restore its initial, clean pressure drop when tested with a clean fluid. A significant, irreversible pressure drop indicates the end of its usable life.
Q3: Can you provide customized sintered filter?
A3: Yes. We can not only provide the standard size, but also the customized filters. We routinely modify end cap designs (e.g., add NPT threads, O-ring grooves, or flanges) and can adjust the overall length or even the filtration rating to meet your specific system integration requirements and performance goals.
Q4: How does the number of sintered layers affect filtration performance, pressure drop, and cleanability?
A: More layers increase:
Mechanical strength – Additional reinforcing layers improve collapse pressure .
Dirt‑holding capacity – Depth loading increases as more layers are added, extending service life before cleaning.
Pressure drop – Each additional layer adds resistance; typically 5‑10% ΔP increase per layer.
Fewer layers offer lower ΔP but less strength and dirt‑holding. Standard recommendation for 30×100: 5‑layer (protective + control + dispersion + 2 reinforcing) balances all factors. Use 7‑layer only for high‑pressure or high‑abrasion applications; use 3‑layer for low‑pressure, high‑flow, clean service.
Q5: What is the difference between 304 and 316L stainless steel for filter elements?
A: 304 stainless steel offers good corrosion resistance and is cost-effective for most general industrial applications.
316L stainless steel contains 2-3% molybdenum, providing superior corrosion resistance to chlorides, acids, and alkalis, making it the preferred choice for marine, offshore, and highly corrosive chemical environments.
Choose 304 for general applications and 316L for demanding corrosive environments.
