A sintered mesh cartridge uses a bonded multilayer metal wall as its filtering medium. The fine control mesh retains solids, while drainage and backing layers support the structure. Forming the laminate into a cylinder and joining it to end fittings creates a replaceable element for process liquid or gas filtration.
The dimensional table lists complete diameter and length combinations with their end-connection options. Plain ends suit assemblies with separate sealing or clamping features. Metric threads connect directly to a mating threaded seat. The 222 and 226 forms use O-ring sealing arrangements; the housing drawing defines insertion depth, seal engagement and locating details.
Choose the nominal media grade alongside fluid viscosity, flow and pressure difference. The active cylindrical surface, end-joint margins and supporting structure determine usable area. An outside diameter alone is insufficient to size the flow path: include active length, the housing bore and the direction of normal filtration and backwashing.
Reusable cartridges are cleaned by backwashing, ultrasonic treatment or deposit-specific chemical cleaning. Protect the sealing surfaces and inspect the seam and end joints after cleaning. For a replacement, measure overall length, sealing diameter, thread pitch and installation clearance. A dimensioned housing interface gives a consistent basis for repeated orders.
The cylindrical laminate is joined along a longitudinal seam, then connected to plain ends, threaded fittings or single-open-end 222/226 adapters. Straight and conical bodies have different developed profiles; the body drawing defines the actual taper and support contact. A flange establishes a mounting face, while an adapter establishes the sealing diameter and insertion depth. The dimensional table groups complete cartridge combinations. Inspection follows each selected row through body geometry, end connection, weld continuity and seal position.
DOE means double open end; SOE means single open end. A 222 or 226 adapter specifies an O-ring sealing and retention interface at the open end of an SOE cartridge. A fin locates the opposite closed end in the housing support. Record both ends on the replacement drawing, together with overall length, seal diameter, insertion depth and any locking lugs.
Dimensions are paired by row. Plain-end fittings, metric threads and O-ring ends provide distinct installation interfaces.

Materials: 304 / 316L stainless steel
Rigid metal cartridges combine a fine control layer with a supported cylindrical wall.
Bonded media and sealed end connections integrate the element into a gas-flow housing.
Defined threads, end seats and cylinder dimensions reproduce the installation interface.
Include these details when discussing your requirements.
The medium defines the porous filtering wall. The complete cartridge adds seams, end fittings, supports and the housing seal.
Measure the thread major diameter and pitch and identify whether the mating connection is internal or external. Include the seating face on the drawing.
Provide the housing interface, O-ring seat dimensions, insertion depth, overall length and locating features.
Compare clean pressure drop or flow before and after cleaning at the same fluid, temperature and flow conditions, then inspect the seals and joints.
