China Stainless Steel Fine Mesh Filter Supplier

Stainless Steel Fine Mesh Filter

Fine mesh filters made from stainless steel are critical for micro‑filtration tasks, capturing sub‑100 µm particles in liquids and gases. Anping CREMOTIVE Wire Mesh Products CO., LTD specializes in fine mesh filters produced by weaving ultra‑fine wires into high‑count Dutch or plain weave patterns.

Fine Mesh Fabrication

• Wire Sourcing & Drawing: 304/316L wires drawn down to 0.03 mm diameter in multi‑stage drawing benches, with annealing between stages to preserve ductility.

• Precision Weaving: Air‑jet looms maintain constant tension, achieving mesh counts up to 400 × 400. Weft:warp wire diameters are paired (e.g., 0.03 mm weft over 0.10 mm warp) to create narrow, uniform slots down to 50 µm.

Element Configurations

• Cartridge Sleeves: Cylindrical fine mesh wrapped around perforated cores, used in high‑pressure housings.

• Disc Filters: Stamped or laser‑cut mesh discs for plate‑and‑frame assemblies.

• Flat Panels: For laboratory sieves and analytical test screens.

Performance Characteristics

• Retention Ratings: Nominal 20 µm to 100 µm, verified via particle challenge tests.

• Open‑Area Ratios: 30 %–40 % to maintain flow rates while achieving fine retention.

• Pressure‑Drop Behavior: Characterized in lab flow benches, enabling accurate system design.

Applications

• Pharmaceutical Purification: Polishing APIs and solvents prior to sterile filtration.

• Ultrafiltration Prefilters: Removing fines before polymeric membrane stages in water treatment.

• Paint & Coatings: Ensuring smooth finishes by filtering pigment suspensions.

• Food & Beverage: Clarification of juices, syrups, and dairy streams—mesh filters withstand CIP and steam‑sterilization cycles.

Inspection & Regeneration
Fine mesh filters undergo:

• Microscopic Aperture Analysis for slot uniformity.

• Bubble‑Point Testing to confirm filtration integrity.
  Filters can be regenerated via reverse backflush, ultrasonic baths, or chemical cleaning; typical service intervals exceed 12 months under normal loading.
