Available in 304/316L stainless steel, aluminum, and copper, it adapts to diverse industries including food processing, pharmaceuticals, and water treatment. Its customizable dimensions (up to 3000×1500mm) and low maintenance requirements make it a cost-effective alternative to disposable filter media, reducing replacement costs by 70%.
Uniform Aperture Precision: Aperture sizes from 0.05mm to 5mm with ±0.01mm tolerance, achieved via laser cutting technology. The 0.05mm aperture suits pharmaceutical liquid filtration (removing 99.9% of 0.1μm+ particles), while the 5mm option is for industrial wastewater pre-screening. Weaving variants (mesh 20-500) offer higher open area for high-throughput applications.
High Structural Flatness: Flatness error ≤ 0.3mm/m ensures tight sealing with filter housings, avoiding bypass flow (filtration efficiency loss < 1%). The screen’s surface roughness Ra < 0.8μm reduces particle adhesion, making cleaning 50% faster than woven screens with rough surfaces.
Customizable Material & Thickness: Material options include 304 stainless steel (corrosion resistance for neutral media), 316L (acid/alkali resistance, pH 2-12), and aluminum (lightweight for portable equipment). Thickness ranges from 0.2mm to 5mm—0.2mm for low-pressure filtration, 5mm for heavy-duty screening (e.g., ore classification).
Long Service Life & Reusability: Washable and corrosion-resistant design extends service life to 2-5 years (vs. 3-6 months for paper filters). Ultrasonic cleaning (40kHz, 20 minutes) restores 98% of initial flow capacity. A food factory reported $20,000/year savings by replacing disposable filters with flat metal screens.
Food & Beverage: Juice clarification and beer filtration. A German brewery used 0.1mm 316L flat metal screens for beer diatomaceous earth filtration, complying with FDA 21 CFR Part 177 standards and improving clarification efficiency by 20%. Juice processing plants use 0.5mm screens to remove pulp, reducing product loss by 3%.
Pharmaceuticals: Sterile filtration of injectable solutions. An Indian pharmaceutical company adopted 0.22mm laser-cut flat screens, achieving USP <788> compliance (99.99% particle removal) and reducing product rejection rate by 4%. The screens withstand autoclaving (121°C, 30 minutes) for 50+ cycles.
Water Treatment: Municipal wastewater primary screening. A city wastewater plant used 2mm flat metal screens to remove debris (rags, plastics), reducing downstream pump clogging by 85%. The screens’ high open area (40%) ensures throughput of 1000 m³/h per unit.
Q: Which material fits acidic liquid filtration (pH 3)?
A: 316L stainless steel is ideal for pH 3 acidic media, with corrosion rate < 0.02mm/year. For stronger acids (pH < 2), choose Hastelloy C276 (corrosion rate < 0.01mm/year) but at 2x the cost of 316L. Avoid 304 stainless steel, which corrodes rapidly in acidic environments.
Q: What’s the maximum custom size for flat metal screens?
A: Up to 3000mm (length) × 1500mm (width) with laser cutting; woven variants max out at 2000×1000mm. For larger sizes (3000×2000mm), connect multiple screens via stainless steel bolts (8.8-grade) with gasket seals—this maintains flatness error ≤ 0.5mm/m.
Q: Can it be used for high-temperature applications?
A: Yes, 316L variants operate stably up to 300°C; Inconel 625 screens handle up to 800°C. A chemical plant used 316L flat screens for 250°C solvent filtration, with no thermal deformation after 12 months. Avoid aluminum screens above 150°C (softening point).
Q: How to install flat metal screens in filter housings?
A: Use housing retainer clips or bolted flanges. For circular screens, ensure the O-ring (EPDM or Viton) is compressed to 20% of its thickness to prevent bypass. For rectangular screens, use gasketed frames to seal all edges—unsealed edges reduce filtration efficiency by 40%.
