Filtro antipolvere per ventola posteriore Lian Li O11 Dynamic XL, DEMCiflex (nero/nero)

The DEMCiflex dust filter is made for the rear fan mounting of the Lian Li O11 Dynamic XL chassis. It provides a replaceable filtration layer that reduces the amount of dust entering the case through the rear fan location while maintaining airflow for cooling. The product matches the case’s black finish and is intended as a direct-fit accessory for systems that use the original rear fan position in the O11 Dynamic XL.

Advantages

This dust filter offers particle filtration with minimal airflow restriction, is finished in black to match the case interior, and is supplied as a purpose-made accessory for the specific rear fan location. It is lightweight, simple to handle during maintenance, and designed for repeated cleaning or replacement to extend component lifetime by reducing dust accumulation on internal hardware.

Suitable for

• Lian Li O11 Dynamic XL systems using the rear fan mounting
• PC builds where reduced dust ingress is desired without major airflow loss
• Regular maintenance routines that include filter cleaning or replacement

Key specifications

• Form factor: rear fan dust filter sized to fit O11 Dynamic XL rear mounting
• Color: black on black finish to match case interior
• Material: flexible mesh filter media with a supporting frame for mounting
• Function: captures airborne dust particles while allowing airflow for fan cooling
• Compatibility: intended for the rear fan location on Lian Li O11 Dynamic XL chassis

How to use

Install the filter over the rear fan mounting in the Lian Li O11 Dynamic XL by aligning the frame with the existing fan screw holes or mounting points and securing it in the same manner as the fan or its cover. Clean the filter periodically by removing it from the case and gently vacuuming or rinsing with water; allow it to dry completely before reinstalling. Replace the filter if it becomes damaged or if cleaning no longer restores adequate airflow.

Recommendations

For effective dust control, inspect the filter every one to three months depending on your environment, and clean more frequently in dusty or pet-friendly spaces. Ensure the filter is fully dry before reinstallation to avoid moisture reaching internal components.
