Stainless steel core filters are filtration devices that use stainless steel mesh or sintered porous metal as the core filtering medium. They are designed for solid-liquid separation, particle retention, and fluid purification in industries such as water treatment, food processing, pharmaceuticals, and chemicals. Key advantages include corrosion resistance, high strength, cleanability, and long service life.
Types of Stainless Steel Core Filters
(1) By Structure
| Type |
Characteristics |
| Stainless Steel Mesh |
Woven wire mesh (e.g., 304/316L), uniform pore size (1-500 μm), ideal for coarse or fine filtration. |
| Sintered Stainless Steel |
Made by high-temperature sintering of metal powder, customizable porosity (0.5-100 μm), high pressure resistance. |
| Multi-Layer Disc Filters |
Stacked mesh layers for enhanced filtration efficiency, suitable for high-flow applications. |
(2) By Filtration Mechanism
-
Surface Filtration (e.g., mesh): Particles trapped on the surface; requires periodic cleaning (backwashing).
-
Depth Filtration (e.g., sintered metal): Particles captured within the porous matrix; higher dirt-holding capacity but harder to regenerate.
2. Key Features & Benefits
Corrosion Resistance: 304/316L stainless steel resists acids, alkalis, and high temperatures (≤400°C).
High Mechanical Strength: Withstands high-pressure fluids (e.g., hydraulic systems, chemical processing).
Reusable & Cleanable: Can be cleaned via backwashing, ultrasonic cleaning, or chemical rinsing.
Non-Contaminating: No fiber shedding, compliant with FDA (food) and GMP (pharmaceutical) standards.
Long Lifespan: Lasts 5-10 years, outperforming PP, ceramic, or activated carbon filters.
3. Applications
