Why a bypass system is needed...

Newer engines, designed to meet strict emission regulations, generate greater amounts of soot in the oil. This soot, along with other solid contaminants, fuel, and water, cannot be effectively and completely removed by full-flow filters alone. This means, without a bypass filtration system designed to remove these contaminants, the oil will become dirty much faster — accelerating engine wear and requiring it to be changed more frequently.
 

How it works...

Contaminated oil enters through the metering jet at a slow measured flow rate.

The oil then passes through the replaceable filter element, where total base number (TBN) additives are replenished and the unbleached, CGP® treated, long-strand cotton fibers, tightly compressed to resist channeling, remove contaminants down to less than one micron, while neutralizing acids and sulfur compounds.

The filtered oil then enters the heated evaporation chamber, where fuel and water are evaporated and immediately vented.

The clean oil is then gravity-fed back to the sump. The puraDYN® bypass oil filtration system does not affect the engine’s oil flow or pressure.

It does not replace the conventional full-flow filtration system - it enhances and works in conjunction with it.

Installation Notes...

The unit is installed downstream of the existing full-flow filter. Contaminated oil, with abrasive particles, soot, liquids and oxidation by-products known as gum and/or varnish, enters the unit through a small metering jet under pressure supplied by the engine's pump. The metering jet prevents any drop in oil pressure and slows the oil down to a low, measured flow rate of six to eight gallons per hour.

Oil passes through the replaceable filter element where the TBN additives are maintained by the patented time-release additive package, while the long-strand cotton fibers trap solid particles down to below 1 micron and neutralize acid and removes sulfur compounds. In addition, puraDYN® filter elements with their optional process for chemical grafting, CGP®, can double the life of the replaceable filter element. The filtered oil then enters the puraDYN® heated evaporation chamber where fuel and water are evaporated and immediately vented. After the dangerous contaminants are removed, the clean oil is gravity-fed back to the engine.
