ThreeBulls 8541607606 12 x 140mm PVC fan filter

ThreeBulls 140mm PVC filter pack

This pack contains 12 black PVC mesh filters cut to 140 by 140 millimetres. They fit standard 14-centimetre case fan mounts and speaker grilles. The material blocks dust while letting air pass through. Installation screws are not supplied.

Sustained dust protection

Over weeks of continuous fan operation the mesh traps airborne particles that would otherwise settle on heatsinks and circuitry. By keeping internal surfaces cleaner the filters help maintain steady airflow and reduce the risk of overheating. Fan noise stays lower because blades remain free of heavy buildup. The PVC construction resists deformation during long-term use.

140mm mounting constraint

Each filter matches a 140-millimetre square opening exactly, so it cannot cover larger or smaller fan frames without modification. The mesh aperture size limits the finest dust it can stop while still allowing adequate air movement. No screws or clips are included, so the builder must provide a separate fastening method. The pack quantity suits multi-fan chassis or spare replacements.
