Equivalent replacement for BEKO coalescing element FE1251XA. The cartridge carries the filtration media inside a compressed air filter housing, where it removes the oil aerosol and liquid water that a mechanical separator leaves behind.BEKO uses letter suffixes such as AC, X1 and XA to distinguish media builds within the same size family. They are not interchangeable with one another, so order to the code printed on the element you are replacing rather than by housing size alone.Related sizes sit under coalescing filter elements, and complete assemblies under coalescing air filters.Note: This is an equivalent part and not an original equipment manufacturer (OEM) part number. Some manufacturers require OEM parts to maintain your warranty. | Air Supply Number: KPE1251XA
