What are separator filters used for?

It is common knowledge that contaminating particles can be found in fuels, both in petrol and in diesel, and unfortunately to a greater extent. Therefore, to preserve the functionality of any engine unaltered, protecting it from severe damages, it is essential to resort to fuel filters. Filters doing their job well must be replaced frequently, especially those for diesel which retain more impurities than petrol ones.

Fuels, contrary to what they are supposed to be, often contain both solid and liquid impurities or in any case foreign bodies. These foreign particles can result from refining processes, contamination in storage, contamination by water that can settle on the bottom of transport tankers, in underground tanks not sealed, or added by man for commercial fraud.

Therefore the delivered fuel can enter any engine that uses it, and the water content forms fungi or other muddy deposits with anaerobic bacterial proliferation, producing corrosion in the tanks and occlusion of the filters of the fuel systems.

What happens if diesel fuel gets contaminated?

Today, this problem is even more common. Considering that the diesel in circulation, according to law, must contain 7% of biodiesel which, being of vegetable origin, is more subject to the formation of bacteria which are harmful to the tanks containing the diesel and therefore for the engines, with a high chance of blockages and machine stoppages.

But not only that, contaminated diesel fuel becomes harmful to modern high-pressure injection systems which are very sensitive to the presence of impurities in the fuel. For example, even a small percentage of water in the diesel not promptly retained by the filter causes severe damage to the injection pump.

Therefore the diesel filters must be very efficient and replaced periodically at scheduled intervals. Its main function is to retain impurities and separate water from diesel which differ in viscosity and specific weight.

For this filtering activity, water-repellent materials are used to deposit the water in the lower parts of the filters until it is replaced.

The separator filters on the market

New decanter filters of new conception are now available on the market, innovative filters that use cartridges with high capacity of separation of water from diesel and effective retention of impurities with filtering of a value of 10 microns.

Filters, in general, are composed of a transparent hard plastic container, internal cartridges, and a closing head which can be of different materials, some of the hard plastic, some of the aluminum quality. The best filters are designed with a valve at the bottom to drain the impurities and condensation water that forms inside.

Why choose a quality filter?

Quality filters have the advantage of allowing the quality control of the diesel oil before being placed in the tanks for both new and old systems. Many companies improve their diesel filtering in working sectors that generally have a fleet of machines to manage. In these sectors, we are proceeding with the assembly of new filter systems or adapted to new technologies.

The CLEAR FILTER brand filter, which is recommended, can be applied to both new and existing tanks. It is effective and innovative, resistant with a transparent casing, purge valve, interchangeable cartridges with 10-micron water/impurity separation sectors with excellent filtering power and good durability.
