PC Case Magnetic Dust Filter is used for catching dust at the fan intakes of desktop PCs and industrial computers with a stiff stainless mesh held on by a magnetic frame. 120 mm form factor is the reference cited for it on drawings, datasheets and purchase orders.
What 120 mm form factor Means for PC Case Magnetic Dust Filter
The dimensions in the table below are supplied to suit 120 mm form factor. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
PC Case Magnetic Dust Filter Dimensions
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Material |
|---|---|---|---|---|---|
| 60-Mesh | 0.190 | 0.233 | 233 | 30.4 | SS304, magnetic frame |
| 80-Mesh | 0.140 | 0.177 | 178 | 31.3 | SS304, magnetic frame |

Specifying PC Case Magnetic Dust Filter Beyond the Standard
- Mesh count: 60-mesh for strong airflow; 100-mesh for dusty rooms or pet hair.
- Frame & magnet: A flexible magnetic strip frame snaps to steel panels; specify outer size to the fan grid.
- Airflow trade-off: Finer meshes raise intake restriction; pair them with high static-pressure fans.
When PC Case Magnetic Dust Filter Is Not the Right Choice
Not a replacement for HEPA filtration in cleanrooms or labs with fine particulate.
