Caterpillar Series Air Filter

KANGXIN Caterpillar series air filters for construction machinery. The main filter uses Longde or Chentai filter paper and the safety core uses Longde filter paper. PU foam bonding between the plastic shell and filter paper replaces simple hot-melt adhesive, ensuring solid adhesion that will not fall off. Shells are made of ABS or nylon as original. Each filter passes light-source testing: as long as light cannot penetrate the filter paper, the filter is qualified.
