Magnetic 120mm Fan Filters

Westinghouse PCFDFMFM-120-4 supplies four black magnetic frames that fit 120mm case fans. Each frame uses PVC mesh with a 0.8mm hole size and 0.45mm thickness to trap dust while maintaining airflow. The magnetic strips attach directly to steel chassis panels without screws or tools. The pack covers four fan positions in a single purchase.

Builders with Steel Cases

These filters suit anyone running 120mm fans on a ferromagnetic case who wants to reduce dust intake and fan noise. They do not adhere to aluminium or non-magnetic panels, so builders with those chassis types cannot use the magnetic mounting. Users needing filtration for other fan diameters will require different products.

0.8mm Mesh Hole Size

The 0.8mm aperture determines how much dust is blocked versus how freely air passes through the fan. This single measurement decides whether the filter matches the builder's balance of cleanliness and cooling performance.

Questions about this item

How much airflow does the .8 mm mesh let through once it is fitted to a 120 mm fan?

The .8 mm openings keep dust out while still allowing air to pass, so the fan can move its rated volume with only a small pressure drop.

What surface does the magnetic frame need to attach securely?

The magnets grip only ferrous metal such as a steel case panel or fan housing; they will not hold on aluminium or plastic.

How much clearance does the .45 mm thick filter add to a standard 120 mm mounting?

At .45 mm it adds virtually no height, so the fan sits almost flush against the grille or panel.
