Buyers often search for “50 micron nylon filter mesh,” but the current INCE filtration reference table does not list an exact 50 µm woven opening. The nearest standard constructions are 48 µm JPP48-279 and 57 µm JPP57-254, both using 43 µm monofilament thread.
The decision should be based on the actual required aperture and service conditions, not the rounded search term alone.
This construction is 2 µm below the nominal 50 µm target. It is the closer listed option by aperture, but final suitability still depends on the real filtration requirement.
This construction is 7 µm above the nominal 50 µm target. It may be considered where the process can accept the larger opening and the exact woven construction is confirmed.
These are the two nearest listed nylon monofilament constructions to a nominal 50 µm buying target.
| Reference | Actual Opening | Difference from 50 µm | Mesh Count / cm | Mesh Count / inch | Thread Diameter | Reference Width |
|---|---|---|---|---|---|---|
| JPP48-279 | 48 µm | −2 µm | 110 | 279 | 43 µm | 127 cm |
| JPP57-254 | 57 µm | +7 µm | 100 | 254 | 43 µm | 127 cm |
50 micron describes a desired clear aperture of about 50 µm. 50 mesh describes a thread/opening count per inch and is a very different specification. For the INCE filtration references nearest 50 µm, the listed mesh counts are 279 mesh/inch at 48 µm and 254 mesh/inch at 57 µm.
A micron value refers to the clear space between adjacent threads. This is the dimension normally used when a buyer asks for a “50 micron nylon filter mesh.”
A mesh count is not a direct micron conversion because thread diameter changes the clear opening. Always specify the actual aperture or an exact reference code.
Use these neighboring exact reference constructions to understand where the nominal 50 µm buying target sits in the INCE filtration range.
120 mesh/cm · 305 mesh/inch · 43 µm thread.
110 mesh/cm · 279 mesh/inch · 43 µm thread. Closest listed opening to 50 µm.
100 mesh/cm · 254 mesh/inch · 43 µm thread. Slightly coarser option.
80 mesh/cm · 203 mesh/inch · 50 µm thread.
After the parent construction is selected, define the final dimensions and fabrication form separately.
Final suitability depends on the selected actual opening, nylon grade, process chemistry, temperature, cleaning method and finished component design.
Fine screening of compatible coatings, inks and process liquids.
Surface screening and equipment protection where nylon is suitable.
Ingredient or process screening only after material and compliance requirements are confirmed.
Particle screening after checking chemistry, concentration and temperature.
Mesh inserts upstream of components that require fine screening.
Discs, screens and custom mesh parts integrated into equipment.
Defined-opening mesh for compatible test and pilot assemblies.
Applications where the selected nylon construction can be cleaned without damage.
Use the rounded 50 µm target to start the inquiry, then lock the production order to the actual selected construction.
Tell us the process calls for approximately 50 µm clear opening and whether a tighter or coarser option is acceptable.
Confirm JPP48-279 or JPP57-254 after reviewing retention, flow and process requirements.
Provide roll length, cut dimensions, disc OD/ID, drawing, process liquid, temperature and quantity.
The current reference table does not list an exact 50 µm woven opening. The nearest listed constructions are 48 µm JPP48-279 and 57 µm JPP57-254.
48 µm JPP48-279 is closer by nominal aperture because it is 2 µm below 50 µm. JPP57-254 is 7 µm above. The closer number is not automatically the correct engineering choice, so verify the actual process requirements.
No. Micron describes the clear opening, while mesh count describes thread density. The nearest INCE filtration options to 50 µm are 279 mesh/inch at 48 µm and 254 mesh/inch at 57 µm.
Mesh size alone does not establish food-contact suitability. Confirm the supplied nylon grade, documentation, process temperature, cleaning chemistry and finished component requirements.
Yes. After selecting the parent mesh, provide disc outside diameter, center-hole size if any, layer count, edge treatment and quantity.
The mesh page covers woven nylon media and fabricated mesh parts. The NMO filter bag page covers a finished liquid filter bag designed for a filter housing.
Send the nominal 50 µm target, preferred actual reference if known, finished dimensions or drawing, process liquid, temperature, cleaning method, quantity and any existing sample.
Send your required opening, process conditions and finished dimensions. INCE filtration can review JPP48-279 and JPP57-254 and confirm which standard construction is appropriate to quote.
