Filtro antipolvo para Lian Li O11 Dynamic (inferior) — DEMCiflex 1104, negro

DEMCiflex 1104 is a bottom dust filter engineered for the Lian Li O11 Dynamic case. It attaches to the lower intake area and provides a physical barrier that reduces dust ingress to the power supply unit and lower-mounted cooling fans while preserving airflow. Finished in black, the filter uses a magnetic/clip-in mounting approach designed for easy removal and cleaning as part of routine case maintenance.

Advantages

The filter reduces particle accumulation on internal components without significantly restricting intake airflow, helping maintain cooling efficiency. Its removable mounting allows fast cleaning and reinstatement, and the black finish integrates unobtrusively with the case aesthetic. The design supports longer intervals between internal cleaning by capturing dust before it reaches the PSU and fan assemblies.

Suitable for

• Users of the Lian Li O11 Dynamic case seeking bottom dust protection
• Systems with lower intake fans and bottom-mounted power supplies
• Environments with moderate dust where regular maintenance is performed

Key specifications

• Compatibility: lower intake of Lian Li O11 Dynamic case
• Mounting: magnetic and clip-in attachment for tool-free removal
• Color: black finish
• Function: dust filtration for PSU and lower fans while maintaining airflow
• Maintenance: washable / removable for periodic cleaning

How to use

Align the filter with the lower intake opening of the Lian Li O11 Dynamic case and attach using the integrated magnets and clips until it is seated flush with the chassis. Inspect the filter periodically and remove it when visibly laden with dust. Clean by gently washing with water or using compressed air, allow to dry completely if washed, then reattach in the same position. Regular inspection and cleaning prolong the effectiveness of the filter and help keep internal components cleaner.

Recommendations

Check the filter every 4–8 weeks in typical home or office environments and more frequently in dusty locations. Avoid using harsh chemicals or abrasives when cleaning; ensure the filter is fully dry before reinstalling to prevent moisture entering the case.
