Filtro de poeira para caixas de computador midi-tower DEMCiflex DF0425 — preto, 292×151 mm

DEMCiflex DF0425 is a black dust filter for Midi Tower computer cases, sized 292×151 mm. Designed to cover ventilation openings, the filter reduces dust entering the chassis and protects cooling components such as fans and radiators. Supplied as a single piece, it is custom made to fit the top vent on an Obsidian 350D case and is suitable for routine maintenance to keep internal airflow paths cleaner and more efficient.

Advantages

The filter uses a fine mesh that captures dust particles while maintaining airflow, helping to preserve cooling performance and reduce the frequency of interior cleaning. Its rigid frame holds the mesh taut for easy installation and removal. The black finish integrates visually with common case interiors and exterior vents. Being a single-piece unit, it is straightforward to replace during maintenance cycles.

Suitable for

• Top ventilation vent on Corsair Obsidian 350D case
• Midi Tower cases with a 292×151 mm top opening
• Protecting fans, radiators and internal components from dust
• Regular case maintenance and airflow preservation

Key specifications

• Color: black
• Dimensions: 292 mm (width) × 151 mm (depth)
• Material: fine dust mesh with rigid frame
• Quantity: single filter piece
• Mounting type: designed for top vent fitting (removable for cleaning)

How to use

Turn off and unplug the computer before attempting installation. Remove the case top or the existing cover as required to access the top ventilation opening. Align the filter with the opening so the frame sits flush against the vent, then press or slide into the mounting channels until it is secure. For cleaning, gently remove the filter, brush or vacuum the mesh surface, and rinse with water if necessary; allow to dry completely before reinstallation.

Recommendations

Inspect the filter every 1–3 months depending on the operating environment; more frequent checks are recommended in dusty conditions. Replace the filter if the mesh becomes damaged or permanently clogged. When cleaning, avoid aggressive scrubbing to prevent deformation of the mesh or frame.
