80 mesh denotes 80 wires per inch in each direction. For washing machine & dryer lint filter mesh the governing document is IEC 60456 / IEC 61121; the specification row, aperture-micron conversion and selection guidance for this count follow.
80 Mesh Specification Row (IEC 60456 / IEC 61121)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Material |
|---|---|---|---|---|---|
| 80-Mesh | 0.140 | 0.177 | 178 | 31.3 | SS304 |
80 Mesh to Micron & Aperture
| Openings per inch | 80 |
|---|---|
| Aperture (opening width) | 0.18 mm |
| Micron rating | 178 µm |
| Standard wire diameter | 0.14 mm |
| Open area | 31.2 % |
Aperture = (25.4 mm ÷ mesh count) − wire diameter. The micron rating equals the aperture in micrometres; actual retention also depends on particle shape and cake formation.
Wire Diameter Options at 80 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.182 mm | 0.136 mm | 136 µm | 18.2 % | 1.36 kg/m² |
| Standard wire | 0.140 mm | 0.178 mm | 178 µm | 31.3 % | 0.81 kg/m² |
| Fine wire | 0.105 mm | 0.213 mm | 213 µm | 44.8 % | 0.45 kg/m² |
Heavier wire adds strength and abrasion life but closes the aperture; finer wire opens the aperture and raises throughput at the cost of durability. Specify mesh count AND wire diameter to fix the aperture unambiguously.
Open Area & Flow at 80 Mesh
The standard 80 mesh weave presents an open area of about 31.2%. At this count the mesh presents little flow resistance; selection is normally driven by particle retention and mechanical strength rather than pressure drop.
80 Mesh Cloth Weight
Standard 80 mesh stainless cloth weighs approximately 0.81 kg/m² (density 7.93 g/cm³ basis; brass and copper weave roughly 10% heavier, aluminum about one third). Use this figure for roll handling and freight estimation.
Typical Applications for 80 Mesh Washing Machine & Dryer Lint Filter Mesh
80 mesh washing machine & dryer lint filter mesh is commonly specified for general straining and sieving, paint and coating filtration, grease filters, insect screening, grain cleaning and pre-filtration ahead of fine media.
Plain, Twill or Dutch Weave at This Rating?
Plain square weave is the standard at this count: every opening is a true square of the stated aperture, retention is absolute for hard spherical particles, and the cloth is easy to clean.
What Washing Machine & Dryer Lint Filter Mesh Does
Trapping lint and fibers in washing machines and tumble dryers before they reach the pump, drain or heater.
Fitting & Care
- Clean dryer lint screens after every load.
- Wash the screen with water and a brush monthly to remove softener film.
