The 60 mesh specification of gas appliance burner & flame arrestor mesh is defined by EN 437 / ANSI Z21 appliance. The tables below reproduce the standard row — wire diameter, aperture and open area — and convert the count to a micron rating for filtration selection. The technical drawing redraws to the values selected.
60 Mesh Specification Row (EN 437 / ANSI Z21 appliance)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Material |
|---|---|---|---|---|---|
| 60-Mesh | 0.180 | 0.243 | 243 | 33.0 | Inconel 600 |
60 Mesh to Micron & Aperture
| Openings per inch | 60 |
|---|---|
| Aperture (opening width) | 0.23 mm |
| Micron rating | 233 µm |
| Standard wire diameter | 0.19 mm |
| Open area | 30.4 % |
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 60 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.247 mm | 0.176 mm | 176 µm | 17.4 % | 1.88 kg/m² |
| Standard wire | 0.190 mm | 0.233 mm | 233 µm | 30.4 % | 1.12 kg/m² |
| Fine wire | 0.143 mm | 0.281 mm | 281 µm | 44.0 % | 0.63 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 60 Mesh
The standard 60 mesh weave presents an open area of about 30.4%. At this count the mesh presents little flow resistance; selection is normally driven by particle retention and mechanical strength rather than pressure drop.
60 Mesh Cloth Weight
Standard 60 mesh stainless cloth weighs approximately 1.12 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 60 Mesh Gas Appliance Burner & Flame Arrestor Mesh
60 mesh gas appliance burner & flame arrestor 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.
When to Step Up or Down from 60 Mesh
Move to 80 mesh when particles are passing that must be retained; drop back to 50 mesh when the element blinds too quickly or the pressure drop is excessive. In a multi-layer pack, pair this count with a coarser support mesh downstream to carry the pressure load.
What Gas Appliance Burner & Flame Arrestor Mesh Does
Forming the flame surface of premix gas burners and the flashback screens inside gas appliances.
Fitting & Care
- Install with even tension so the flame front stays uniform.
- Inspect for oxidation and holes at service.
