4 Layer 80-150 Mesh Flat Bottom Metal Mesh Filter Cartridge Stainless Steel Mesh Filter Element for Reusable Filtration

This 226 flat-bottom metal mesh filter cartridge is a fully reusable stainless steel filter element built on a four-layer woven wire mesh structure. It combines a 226 bayonet (Code 3) adapter on the top with a flat closed bottom end, delivering stable filtration accuracy of 80–150 mesh (approximately 100–180 µm) under high mechanical load, high temperature and high pressure differential. The welded all-metal body contains no fibrous media, so there is no fibre shedding, no media migration and no risk of the element collapsing under reverse flow — an ideal choice for pre-filtration of slurry-type and high-viscosity liquids.

• Four-layer woven mesh structure — protection layer, control layer, dispersion layer and support layer — giving high dirt-holding capacity together with a precisely defined pore size.
• Filtration accuracy selectable from 80 to 150 mesh (about 100–180 µm) with uniform aperture and low initial pressure drop.
• 226 bayonet adapter with flat bottom: fast twist-lock installation, positive O-ring sealing and simple removal for cleaning, with no loose parts to lose.
• All-welded 304 / 316L stainless steel construction — high mechanical strength, no glue line, no extractables from the housing.
• Withstands a design pressure of 0.8 MPa and a maximum working pressure differential of 0.5 MPa without deformation.
• Working temperature up to 480 °C, with excellent resistance to acids, alkalis, solvents and steam.
• Reusable many times over through backwashing, ultrasonic cleaning and acid / alkali CIP, which lowers the cost per cubic metre of filtered liquid.
• Strict control of Cu / Zn content in the wire ensures low extractables, suitable for food, beverage and pharmaceutical pre-filtration.

• Pre-filtration of slurry-type and high-viscosity feed liquids.
• Polymer, resin and melt filtration, including spin-pack and catalyst recovery duty.
• Water treatment, seawater and process water coarse filtration.
• Lubricating oil, fuel oil, hydraulic oil and cutting fluid filtration.
• Syrup, edible oil, beer and beverage clarification.
• Spray booth, dust removal, indoor ventilation and vacuum cleaner parts.
• Ink, coating and chemical intermediate filtration.

1. Backwash with clean liquid in the reverse direction at 0.3–0.5 MPa until the differential pressure returns close to the initial value.
2. For stubborn residue, immerse the element in neutral detergent and clean ultrasonically at about 40 kHz.
3. Caustic and acid CIP cycles are compatible with the 304 / 316L mesh and PTFE seals; check the seal grade before use with aggressive chemicals.
4. Dry or air-blow the element before refitting, and inspect the mesh surface for mechanical damage after each cleaning.

Please confirm the following details when enquiring: filtration accuracy (80–150 mesh), element length (5–40 inch), material grade (SS304 or SS316L), seal material (EPDM, PTFE or silicone), and whether a 226 bayonet adapter with flat bottom or another end-cap configuration is required. Custom mesh counts, diameters and connection codes are available on request.
