Dust filter DEMCiflex DF0078 for computer case, black, 153×42 mm

DEMCiflex DF0078 is a compact black dust filter for computer cases with overall dimensions of 153 × 42 mm. Supplied as a single unit, this rectangular filter is intended to protect internal components from dust accumulation while allowing airflow through small vents or fan intakes. Its slim profile makes it suitable for installations that require a narrow, space-efficient filter, including mounting in standard 1 × 5 1/4 inch front bays or other similarly sized openings.

Advantages

The DEMCiflex DF0078 provides a physical barrier that reduces dust buildup inside the chassis and on components, helping to maintain cooling efficiency and reduce the frequency of internal cleaning. The filter’s compact rectangular shape and black finish allow discreet installation in narrow or visible areas. It is delivered as a single-piece solution that can be used in small vents, fan intakes or custom mounting situations where a 153 × 42 mm filter is required.

Suitable for

• Small ventilation openings on computer cases
• Narrow fan intakes where a compact rectangular filter is needed
• Custom mounting areas and slim front bay installations (1 × 5 1/4 inch front bays)

Key specifications

• Color: black
• Dimensions: 153 × 42 mm (overall size)
• Quantity: 1 filter per pack
• Form factor: slim rectangular filter suitable for narrow openings

How to use

Place the DEMCiflex DF0078 into the vent, fan intake or front bay opening that matches its 153 × 42 mm dimensions. If the mounting area is a standard 1 × 5 1/4 inch front bay, align the filter so it sits securely and does not obstruct fan operation. For non-ferrous mounting surfaces such as aluminium or acrylic, select the appropriate non-ferrous fastener or button if available to avoid magnetic attachment issues. Remove the filter periodically and clean it according to the case manufacturer’s guidance to maintain airflow and filtration effectiveness.

Usage recommendations

Check the opening dimensions before installation to ensure a proper fit. Clean the filter regularly by gently brushing or rinsing with water and allowing it to dry fully before reinstalling. Avoid using the filter in openings significantly smaller or larger than 153 × 42 mm, and use non-ferrous mounting hardware where the mounting surface is aluminium or acrylic.
