Fuel filters HEXEN

Any kind of fuel has both organic and inorganic contaminations that can quickly disable high-precision fuel systems elements. That is why in each fuel system there are filters, which are able to trap dust, rust (formed at inner walls of tank), water as well as living organisms in it. Requirements to fuel filters are strong. The efficiency should exceed 90% and size of passing contaminants should not be bigger than 4 microns. Sometimes in fuel systems are installed two types of filters - fine and primary filtration for satisfaction demands on cleaning quality. As distinct from oil filters, there are no by-pass valves in fuel systems, because engine will stop at once without fuel supply. If not cleaned fuel will get into system - it will cause damages and bring to expensive repairing.

Filtering materials

There are a number of various filtering materials used for fuel filtration, depending on required optimal efficiency and contaminants absorption. They can be special polyester non-woven materials or cellulose based filtering paper applied for fine cleaning. New filtering materials are made of synthetic or semi-synthetic materials combinations, which form multi-layers partition able to trap contaminants selectively. It guarantees prolonged filters service life without loss of fuel purification quality.
Filtering elements, designed for diesel fuel cleaning, also obligatory required to separate efficiently water emulsions from fuel.
