Retention basis
A nominal micron claim is not interchangeable with a specified aperture or validated filtration result. Define the medium, test method and acceptance criterion for the duty before comparing woven and sintered options.
Media and construction
Sintered mesh laminates provide a rigid cleanable construction; woven media and multilayer packs can be configured for different handling and pressure requirements. Specify end connections, cleanability and material compatibility with process and cleaning chemicals.
Information for quotation
Share solvent composition, temperature, flow, allowable differential pressure, rating basis, material requirements, interface drawings and documentation scope. If a regulated process needs validation records, agree the tests and traceability requirements in the purchase order.
Design review
Compare a rigid sintered laminate, fiber felt and pleated woven element on the required rating basis, pressure load, cleaning route and solvent compatibility. Particle retention cannot be assumed from a nominal micron label. For a regulated process, define whether the part is a process screen, a validated filter element or an equipment spare, because the evidence required differs.
Inspection and acceptance
Agree the drawing revision, wetted material list, surface or cleaning requirements, sampling, inspection and records before an order. Documentation supplied for one batch does not automatically validate another process. The customer remains responsible for approval in the complete system and for any regulated qualification.
Specify the porous body and its solid connections separately
The filtering body, support and housing connection have different functions. A pleated element needs drainage between folds; a sintered-mesh cylinder needs a defined joining zone; a powder element has a porous wall and solid end fitting. Identify which surface sees the incoming fluid and how the clean side is sealed.
List every contacting alloy and seal alongside the process and cleaning media. The assembly drawing locates welds, support contact and removable interfaces. The inspection schedule then pairs media identity and its test basis with finished dimensions and connection checks, preserving the link between the selected medium and the supplied component.
