Dust filter DEMCiflex 0306 for PC, black/grey, 120 mm x 370.1 mm

DEMCiflex 0306 dust filter for PC is a slim, magnetic-compatible filter intended to reduce dust ingress through chassis ventilation while maintaining airflow. With a finished size of 120 mm × 370.1 mm and a two-tone black/grey appearance, this filter fits over standard 120 mm fan openings and elongated vents. It is compatible with side or front panel vents and fan/filter slots in desktop PC cases, and is custom-made to cover ferrous or non-ferrous vents of an XSPC AX triple 120 mm radiator fan.

Advantages

The DEMCiflex 0306 combines fine mesh filtration with a flexible frame to provide continuous airflow while capturing dust particles. Its dimensions and shape are designed for easy alignment over rectangular or elongated fan vents. The black/grey finish integrates unobtrusively with most chassis interiors and exteriors. The filter’s construction allows for straightforward maintenance: it can be removed, cleaned, and reinstalled without tools when used with magnetic or clip-down mounting surfaces.

Suitable for

• Filtering intake or exhaust air on ATX and smaller desktop PC cases
• Protecting radiator fan arrays, including XSPC AX triple 120 mm radiator fan vents
• Use on side, front or top panels with elongated fan slots or rectangular vents
• Systems where regular dust maintenance is needed to preserve airflow and cooling efficiency

Key specifications

• Finished dimensions: 120 mm (width) × 370.1 mm (height)
• Colour: black/grey
• Material: fine dust mesh with flexible frame suitable for magnetic or adhesive mounting (dependent on chassis)
• Compatibility: designed for 120 mm fan-based vents and elongated radiator fan openings
• Form factor: slim profile intended for minimal airflow restriction

How to use

Place the DEMCiflex 0306 filter flat over the targeted vent or fan slot, aligning the edges with the chassis opening. If the case surface is ferrous and the filter uses magnetic attachment, allow the filter to seat magnetically; if using adhesive or clip mounting, secure according to the case mounting method. For radiator fan arrays such as an XSPC AX triple 120 mm, position the filter to fully cover the vent area without compressing the radiator fins or obstructing fan blades. Remove the filter periodically and clean it by gently rinsing with water or using compressed air, then dry thoroughly before reinstalling.

Recommendations

Inspect and clean the filter every 4–12 weeks depending on ambient dust levels and system usage. Avoid using harsh detergents or abrasive tools when cleaning to preserve the mesh. Ensure the filter does not contact moving fan blades; allow slight clearance to prevent vibration or noise.
