Stoffilter DEMCiflex Triple 120mm O/D voor computerventilatieopeningen, zwart, 120×360 mm

DEMCiflex Triple 120mm O/D is a black dust filter designed for computer vents with an overall size of 120 × 360 mm and an effective filter area of 92 × 332 mm. The filter uses a triple-layer mesh to capture dust particles while maintaining air permeability, and is intended for mounting over 120 mm fan openings or equivalent vent cutouts. Sold as a single piece, the filter fits front, top or side vents and helps reduce dust accumulation on internal components and maintenance frequency.

Advantages

The triple-layer construction combines fine filtration with structural stability, allowing airflow while trapping a wide range of dust sizes. Its slim profile and black finish integrate with most PC cases without obstructing fan operation. Designed to cover 120 mm openings across a 120 × 360 mm frame, the filter offers a simple protective barrier that is easy to install and remove for cleaning.

Suitable for

• Cases with 120 mm fan openings or vent cutouts matching the overall 120 × 360 mm frame
• Front, top or side ventilation panels where a slim, removable dust filter is needed
• Systems requiring reduced dust ingress to protect fans, heatsinks and internal components

Key specifications

• Overall dimensions: 120 × 360 mm

• Color: black
• Mounting: designed for 120 mm fan openings / compatible vent cutouts

How to use

Place the filter over the target vent or fan opening so the effective filter area covers the airflow path. If the vent frame is made from non-ferrous material such as aluminium or acrylic, select the non‑ferrous mounting option if applicable. Secure the filter using the case's existing screw points, magnets or clips as appropriate for your case design. Remove the filter periodically to clean accumulated dust; cleaning frequency depends on ambient dust levels and system usage.

Recommendations

Clean the filter by gently vacuuming or rinsing with water and allowing it to dry completely before reinstalling. Avoid harsh chemicals or high-temperature drying to preserve the mesh. Inspect fit to ensure the effective filter area fully covers the vent opening to maintain optimal protection and airflow.
