Introduction To Stainless Steel Mesh Filter Bag

Stainless Steel Bag Filter Core Data:

Filter precision: 1–200 μm (commonly 5–100 μm).

Operating temperature: -200°C to +550°C (material-dependent).

Pressure resistance: ≤1.0 MPa (depending on frame structure).

Pore size: 15–50% (affects flux and pressure drop).

Thickness: 0.1–1.0 mm

Air permeability: 100–1000 L/m²s (at 200Pa).

Acid–alkali resistance: pH 2–13 (316L exhibits optimal corrosion resistance).

Stainless Steel Mesh Filter Bag Typical Scenarios:

1. Chemical/Petrochemical:

– Filtration of strong acids and alkalis (e.g., sulfuric acid, sodium hydroxide).

-Catalyst recovery and solvent purification

2. Pharmaceutical & Bioengineering:

-High-temperature sterilization, filtration, solid-liquid separation of fermentation broth

-GMP-grade clean fluid processing

3.Food & Beverage:

-Refined edible oil filtration, decarbonization of syrups, beer wort filtration

4.Environmental & Energy:

-Flue gas dust removal (high-temperature conditions), metal particle capture in wastewater

-Lithium battery slurry filtration, photovoltaic silicon purification

5.Mechanical Manufacturing:

-Cutting fluid regeneration, electroplating solution purification

Stainless Steel Filter Bag Selection Notes:

1. Media Compatibility: 316L stainless steel must be used in environments with chloride ion concentration exceeding 50 ppm;

2.Precision Matching: Select nominal filter precision equivalent to 1/3 of target particle size (e.g., 5-7 μm filter bags for 20 μm particle retention);

3.Flow Design: Calculate initial pressure drop based on porosity to prevent overload operation;

4. Regeneration Strategy: For high-frequency cleaning applications, prioritize thick plain weave structures to avoid clogging from dense weave patterns.

Summary: Stainless Steel Mesh Filter Bags are a highly reliable filtration solution for demanding industrial conditions. With their exceptional environmental resistance, long service life, and cleaning advantages, they have become indispensable filtration consumables in chemical, pharmaceutical, and advanced manufacturing sectors. When selecting the right model, it's essential to comprehensively consider medium characteristics, precision requirements, and cost models to maximize their technical
