Filter Material: Monolayer Polyester Non-woven Fabric.
Filter Type: Dry-type panel filter (100% oil-free, eliminating risk of contaminating or fouling the Mass Airflow / MAF sensor).
Filter Structure: Density Gradient Structure. The filter density progressively transitions from a loose, porous outer layer to a highly compressed, fine internal layer. This design uses the entire depth of the filter (depth loading) rather than just the surface, preventing early clogging.
Thickness: 25mm ±3mm.
Filtration Efficiency: Captures >95% of dust particles under strict industrial testing conditions.
Filter Media Color: White (allows easy visual detection of dirt accumulation)
