One essential condition required for an internal combustion engine to operate properly is to constantly lubricate the moving parts of the engine with oils maintained at the necessary level of cleanliness so as to prevent any premature wear. The oil filter provides continuous purification of the oil, by retaining abrasive particles which are caused by normal wear and tear, and also dust and combustion residues. Oil filters can be designed as "spin-on filter" or as "filter-cartridge" in housing. A spin-on filter is replaced completely after its useful life whereas in the other version only the cartridge needs to be replaced in the housing. By using the latest OE technologies, FRAM® offers its aftermarket clients the highest performance filters. In addition, thanks to constant value analysis, FRAM® is able to produce increasingly compact and lightweight filters thereby reducing the amount of recycling which helps to protect the environment. As an automotive filtration leader, FRAM® plays an active part in the ISO standardization committees and has greatly contributed to establishing new modern test methods that are accurate and reliable. In particular, filter efficiency as a function of particle size can be evaluated. FRAM® is offering to the most demanding aftermarket customers an extensive oil filter range, constantly updated following the market demand.
