Outer Primary Filter AF26124
Thickened integrated rubber sealing end cap: Multi-groove annular sealing design with central positioning boss, forming full airtight fit with air cleaner housing to prevent unfiltered dust bypass leakage.
High-performance composite filter media: High-capacity dust-holding pleated filter paper compounded with wood pulp and micro glass fiber, with hydrophobic impregnation treatment to resist moisture and clogging.
Double-layer metal protective mesh: Outer anti-rust perforated metal mesh and inner supporting mesh effectively lock filter paper shape, avoiding collapse under high intake negative pressure during full-load operation.
