SMALL FITTING FILTER 2 MICRONS 1147147

Function and technical context

The Racor RAC2010SM-OR 2 micron filter acts as a high-precision barrier in the fuel supply circuit of marine diesel engines, retaining solid particles, sediments and emulsified water present in the diesel before they reach the injection pump and injectors. It works within the fuel pre-filtration system, usually located between the tank and the charging pump, constituting the first and most critical line of defense of the injection train. Its 2 micron retention capacity ensures extraordinarily fine fuel purification, protecting high-tolerance components such as precision injectors from contamination that causes premature wear, loss of power and costly breakdowns. The brown filter element and its compact design make it especially suitable for installations with reduced space in the machine room, without sacrificing filtration efficiency. Volvo Penta reference 1147147 identifies this filter as a valid spare part for a wide range of the brand's marine diesel engines.

When to replace this part?

The most common symptoms that indicate that the Racor fuel filter requires replacement are: difficulty starting when cold, drops in speed or loss of power under load, unexpected engine stops and the presence of water or visible turbidity in the separator tank. For this type of marine fuel filter, it is recommended to replace it every 100-200 hours of operation or at the beginning of each nautical season, changing it earlier if the separator vacuum gauge indicates clogging or if the stored fuel has remained in the tank for a long time. Replacing the filter element preventively, before it shows signs of obstruction, is the most effective measure to avoid an engine stop while sailing and protect the injection system against high-cost repairs.
