5 Layer Sintered Wire Mesh Filter Cartridge Stainless Steel with 226 Bayonet Adapter and 1-200 Micron Rating

5-Layer Sintered Stainless Steel Wire Mesh Filter Cartridge with 226 Bayonet Adapter and Flat Bottom — nominal filtration rating 1–200 µm.

This cartridge is built from a five-layer sintered wire mesh laminate. Woven mesh layers of graded aperture are stacked, then diffusion-bonded in a vacuum furnace under heat and pressure, so the layers join at the wire contact points without adhesive, resin or binder. The result is a single homogeneous porous plate whose pore channels are defined geometrically by the intersection of the control-layer wires rather than by fibre entanglement, which gives a fixed, reproducible nominal rating and a bubble point that can be verified piece by piece. The laminate is then formed and welded onto a 226 bayonet adapter at the top and a flat closed bottom at the base to produce a rigid, cleanable filter element.

The cartridge uses the standard five-layer stack, written in the sequence protection + control + dispersion + reinforcing + reinforcing:

• Fixed pore geometry: the rating is set by the control-layer weave, so the pore size is uniform and does not shift with flow rate or differential pressure.
• Diffusion-bonded laminate: no binder, no fibre shedding, no media migration; the element behaves as one solid plate rather than stacked screens.
• High mechanical strength and pressure resistance: the crimped reinforcing layers carry the load, so the cylinder does not collapse under reverse pressure pulses.
• Service temperature up to 480 °C and full compatibility with steam sterilisation and hot-gas filtration.
• Corrosion resistance in SS304 / SS316L against acids, alkalis, solvents, seawater and process chemicals.
• High permeability and low clean pressure drop at a given rating, which keeps pump energy demand down.
• Cleanable and reusable: backwash, ultrasonic, caustic / acid CIP and high-temperature burn-off are all suitable, restoring permeability repeatedly.
• Fabricable: the laminate can be cut, pleated, rolled, TIG welded and machined into cylinders and cone configurations to match standard housings.

• Top connection: 226 bayonet adapter (Code 3), machined in SS304 / SS316L and TIG welded to the sintered cylinder for a crevice-free joint.
• Bottom: flat closed end cap, plain or with a locating boss, providing a rigid base that seats on the housing standpipe.
• Sealing: EPDM, PTFE or silicone O-ring on the adapter, selected to the process temperature and chemistry.
• Internal support: perforated or spiral center core keeps the laminate geometrically stable during pressure pulsing.
• Standard element lengths: 5, 10, 20, 30 and 40 inch, with custom diameters, mesh combinations and layer counts available.

• Fine and pre-filtration of liquids and gases in chemical and pharmaceutical processes.
• Polymer and melt filtration, spin-pack screens and catalyst recovery.
• Water treatment, desalination pre-filtration and condensate polishing.
• Oil and gas duty: well drilling fluids, refining and hydraulic circuits.
• Food and beverage processing, including edible oil and syrup clarification.
• High-temperature gas filtration, air filtration in automotive and aerospace processes.
• Environmental protection, dust removal and pollution control equipment.

1. Bubble point test on the finished laminate to confirm the nominal rating of the control layer.
2. Air permeability test against the standard value for the selected rating, with recorded deviation.
3. Thickness and basis weight check to verify layer count and reinforcing structure.
4. Visual and weld inspection of the 226 adapter, flat bottom and center core before packing.

Please state the nominal rating in micron (1–200 µm), material grade (SS304 or SS316L), element length and diameter, end connection (226 bayonet with flat bottom as standard, other codes on request), seal material and the process medium with its working temperature and differential pressure. For multi-specification orders, list each rating separately so that layer structure and price can be quoted item by item.
