What Is 400 Micron Polyester Filter Mesh?
400 micron polyester filter mesh is woven PET monofilament fabric specified by a target clear opening of 400 µm (0.4 mm). Incefiltration supplies polyester mesh in rolls and reviews cut pieces, discs and OEM components by specification. This is a raw woven mesh selection, not a finished filter-bag rating.
Nearest size comparison
Compare 300 µm when a smaller opening is required and 500 µm when a half-millimetre target is acceptable.
What your quote must confirm
Actual clear opening and tolerance, PET grade, thread diameter, mesh count, usable dimensions and finished-part requirements. A micron target alone does not identify a complete production specification.
Range reference: Incefiltration polyester mesh specification guide. For application-specific confirmation, send your sample or drawing to Incefiltration.
400 Micron PET Mesh Specifications
Use this specification checklist to request 400 micron polyester mesh fabric. The final woven construction and availability are confirmed during quotation.
| Parameter | Requirement / confirmation |
|---|---|
| Target clear opening | 400 µm / 0.4 mm; state your acceptable tolerance |
| Material | Polyester (PET) monofilament; exact grade to be confirmed |
| Mesh count | Confirm count per inch or centimetre for the offered weave |
| Thread diameter / open area | Confirm against the selected production specification |
| Roll or part dimensions | Specify usable width and length, or drawing dimensions and tolerances |
| Supply format | Rolls, cut pieces, discs, rings, tubes or OEM screens for review |
| Operating conditions | Liquid chemistry, temperature, viscosity, flow, pressure differential and cleaning |
| Inspection / documentation | Agree aperture inspection, sample approval and application-specific documentation |
Opening is not an absolute filtration rating. Woven aperture describes geometry. Retention depends on particle shape, deformation, tolerances and sealing. Define efficiency and test conditions separately where required.
Selecting a 400 µm Opening
Compare 300 µm when a smaller opening is required and 500 µm when a half-millimetre target is acceptable.
300 Micron Polyester Mesh
0.3 mm target. 100 µm smaller than the 400 µm target. Finer opening target than this page.

0.4 mm target. Current selection; confirm production tolerance.
500 Micron Polyester Mesh
0.5 mm target. 100 µm larger than the 400 µm target. Coarser opening target than this page.
Explore 500 µm specifications →Micron and mesh count are different. 400 micron is not 400 mesh. The thread diameter is needed to relate an aperture to a mesh count. Flow also depends on open area, viscosity, screen size and solids loading.
Polyester Mesh Rolls, Discs & Custom Parts
Rolls & cut pieces
Specify roll width, roll length or cut dimensions. Confirm usable width, cutting tolerance and packaging for conversion or assembly.
Discs & rings
Provide outside and inside diameters, dimensional tolerances and edge treatment. Check support and sealing in the installed part.
Explore filter mesh discs →Tubes & OEM screens
Submit drawings showing joints, frame contact, mounting and inspection criteria. Fabrication suitability is reviewed for the selected weave.
Custom mesh fabrication →Where to Evaluate 400 Micron Polyester Mesh
Larger-debris screening
Examine edge leakage and support under load: bypass around a screen can defeat an otherwise suitable mesh aperture.
Compatible process liquids
Review PET compatibility with the full formulation, operating temperature and cleaning agents. Test for acceptable particle removal without unwanted retention of useful ingredients.
OEM filter components
Evaluate the assembled screen, including support, edge sealing and joints. For food-contact duties, request documentation for the exact material and intended conditions.

400 Micron Polyester Filter Mesh FAQ
What does 400 micron polyester filter mesh mean?
It describes a 400 µm (0.4 mm) clear-opening target for woven polyester monofilament mesh. Confirm the offered production aperture and tolerance before ordering.
Is 400 micron the same as 400 mesh?
No. Micron measures opening size; mesh count describes the number of mesh periods per inch or centimetre. Thread diameter is also required to relate the two.
Is an exact 400 µm construction confirmed?
The polyester mesh range lists this size as a purchasing target. The quotation must confirm the actual aperture, mesh count, thread diameter, open area and available width.
Does this mesh provide absolute filtration?
The opening is a geometric specification, not a guaranteed retention efficiency. Particle shape, deformation, sealing and process conditions affect performance. Specify a test method and efficiency requirement if needed.
Can I order custom discs or cut pieces?
Incefiltration can review rolls, cut pieces, discs, rings, tubes and OEM screens. Send dimensions, tolerances, edge finish and quantity with the selected opening target.
What should I check for chemical or food-contact use?
Confirm the exact PET grade, liquid composition, temperature and cleaning conditions. Request documentation for the intended food-contact use and destination market when applicable.
Why should I check the seals on a 400 micron mesh screen?
Examine edge leakage and support under load: bypass around a screen can defeat an otherwise suitable mesh aperture. Compare 300 µm when a smaller opening is required and 500 µm when a half-millimetre target is acceptable.
