Protecting your engine from contaminants is essential. More precise engineering leaves less room between machine components than before, so choosing the correct filter is more important than ever. Cat Advanced High Efficiency Engine Oil Filters increase contamination control performance providing for a much cleaner running engine lubrication system and provide enhanced filtration without the shorter change intervals often required by other brands’ higher efficiency filters. The Cat 1R-1807 filter contains a higher efficiency filter media. This media is designed to increase contaminant capturing efficiency while maintaining excellent dirt holding capacity characteristics. Consistent Quality from Filter to Filter, Caterpillar engineers its liquid filters to avoid metal contaminants, leaks, pleat bunching and movement. This is what makes CAT engine oil filters supreme: Spiral roving and beading for pleat stability to better trap and hold particles Properly cured filter media for long performance and life One-piece aluminum base plate Strong nylon center tubes to prevent metal contamination A heavy gauge canister for structural strength One-piece molded urethane end caps to eliminate leaks Caterpillar manufactures over 80 percent of its liquid filter volume on an automated assembly line. This strict quality control eliminates variation from part to part. Advanced High Efficiency filters offer better filtration efficiency than standard oil filters, improved engine cleanliness and a longer component life.
