About Oil Filters

Oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil.
Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps.

FILTRAFLUX oil filters make sure that dust and any water in the oil won’t harm your engine. They help you avoid the problems that come with low-quality products. Plus, they protect your vehicle’s injection system from wear and corrosion, keeping your engine running steadily and extending the life of the injection system.

Modern engine oil filters tend to be “full-flow” (inline) or “bypass”.

Full-flow Oil Filter

A full-flow system will have a pump which sends pressurised oil through a filter to the engine bearings, after which the oil returns by gravity to the sump.

In the case of a dry sump engine, the oil that reaches the sump is evacuated by a second pump to a remote oil tank.

The function of the full-flow filter is to protect the engine from wear through abrasion.

Bypass Oil Filter

Bypass oil filter systems are secondary systems whereby a bleed from the main oil pump supplies oil to the bypass filter, the oil then passing not to the engine but returning to the sump or oil tank.

The purpose of the bypass is to have a secondary filtration system to keep the oil in good condition, free of dirt, soot and water, providing much smaller particle retention than is practical for full flow filtration.
