The Frantz Filter Bypass System is the most efficient oil filter that is commercially available for engines today. Even after many thousands of miles of use, oil filtered through a Frantz Filter Bypass System will be free of contamination to such a degree that it is considered analytically clean and suitable for further use.

Bypass filters remove solid contamination from lubricating oil. These types of filters are capable of removing extremely small size particles from the oil by providing filtration in depth through a densely packed filtering media. Oil flow through the bypass type filter is controlled at a rate so deliberate that it can trap and remove from the oil extremely small solid particles.
