Construction
How the cartridge is built
- Pleats need drainagePleat spacing and drainage paths give fluid access to the filtering surface and provide routes for contaminant removal. Compare the exposed, usable pleat area together with these channels.
- Rigid versus flexible mediaSintered laminates provide a bonded screen structure; metal fiber felt provides a fibrous depth-filtration pathway. Specify the construction and retention test for each medium.
- End-cap jointsThe media-to-cap joint and the housing O-ring each form part of the filtration boundary. Check the continuity of the joint and the fit of the housing seal separately.
- Five-layer packSintering bonds the control and support layers into a stable laminate. The selected mesh layers, wire diameters and weave define its pore geometry.

Describe a replacement in three dimension groups
Installation dimensions define the housing interface: overall length, mating diameters, end connections, insertion depth and seal location. Active dimensions define the exposed filtering length and the surface remaining after end-cap lands and covered regions. Structural dimensions describe the core, protective cage and media-to-cap joints. Recording all three groups reproduces the complete cartridge.
DOE ends seal against the housing arrangement; an SOE cartridge has one closed end and a defined open-end connection. For 222 and 226 interfaces, record the spigot, O-ring engagement and locating features. Threaded and flanged ends use their own seating surfaces. The filter-to-housing joint and the joint between medium and end cap both form the separation boundary.
Connect active area, drainage and cleaning
In a pleated cartridge, drainage spaces between folds and the supporting core make the media surface accessible to flow. In a sintered-mesh tube, the bonded wall and its supports define a rigid filtering body. Fiber felt provides a fibrous porous structure and is supplied with the support arrangement of the selected cartridge. Compare these constructions with the same fluid, temperature and operating flow.
Include normal filtration, contaminant removal and the return to service in the specification. The cleaning method must reach the dirty-side surface and remove deposits from joints and folds. Record forward and reverse flow directions, the corresponding supports and the inspection of media and end-cap joints after cleaning. The cartridge is then defined through its full operating cycle.
What we need to quote a cartridge
Specify media type, retention, end connection, housing bore and differential pressure together to define a complete cartridge.
Retention
Give aperture plus wire diameter for woven media, or a tested rating for porous media.
Effective area
Compare usable pleat area, excluding end-cap bands and blocked regions.
Connections
Provide seal diameters, groove dimensions, thread designation and insertion depth.
Pressure
Separate line pressure from differential pressure across the element; include cleaning reversal.
Media type
Pleated woven mesh · five-layer sintered mesh · metal fibre felt
Rating
Stainless-steel mesh configurations for liquids: 2–840 µm. Specify gas-service grades with their own test conditions.
Cartridge drawing: separate fit from filtering structure
Use these groups when preparing a drawing or comparing a replacement sample.
| Dimension group | What to record | Purpose | Assembly check |
|---|---|---|---|
| Housing fit | Overall length, mating diameters and end connection | Locates and retains the cartridge | Seat, insertion and removal space |
| Active medium | Filtering length, pleats or porous wall and covered lands | Defines exposed filtering surface | Medium identity and accessible area |
| Support and drainage | Core, cage and flow paths between layers | Supports the medium through the flow cycle | Position and continuity of supports |
| Sealing boundary | Seal position, cap joint and media seam | Separates clean and dirty sides | Joint continuity and seal engagement |
Metal filter cartridges
Applications
All-metal cartridges serve where temperature, differential pressure or chemical attack rules out polymer elements.
Process liquid filtration
Removable elements for oil, resin and chemical liquids; material and seals follow actual chemistry.
Hot gas and vent duties
Match the temperature conditions of the metal medium, joints and seals to define the assembled cartridge for hot-gas or vent service.
Equipment replacement
Match the original flow direction and end connection before comparing media grades.
Cartridge checks that affect service
Inspect the complete filtration boundary from media joints to the housing seal.
End connection
Check mating diameters, thread fit and seal location.
Media and core
Check media identity, pleat spacing and core continuity.
Assembly integrity
Inspect longitudinal and cap joints; specify an integrity test when the duty requires one.
Check the assembled flow boundary
Inspect the media seam, cap joints and sealing interface together. Record the active filtering length, support position and fitted dimensions against the cartridge drawing.

Questions before ordering
Does a longer cartridge always provide more flow?
It usually provides more media area, but ports, internal core, viscosity and housing losses may still limit flow. Compare pressure loss at the same fluid, temperature and contamination condition.
Can the cartridge be backwashed?
Backwashing needs media support in the reverse direction and joints that tolerate the cleaning cycle. A collapse rating in normal flow does not establish the reverse-pressure limit.
When is a rigid sintered cartridge preferable to a pleated mesh cartridge?
A rigid porous wall can simplify cleaning and support in some duties; a pleated mesh construction increases surface area within the same envelope. Compare retention, differential pressure and cleaning method at the required flow.
What should accompany a replacement-cartridge sample?
Provide the mating housing or its interface drawing, normal flow direction, cleaning method and the required filtration definition. Record the medium construction as well as the external dimensions so that the replacement retains the same functional layout.
How should active pleated area be described?
Identify the exposed pleat length, fold geometry, end-cap coverage and available drainage paths. The active area belongs to the assembled cartridge with its supports and end connections.
