## Long description

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

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.
