BEKO Coalescing Element FE851AC An equivalent replacement coalescing element for BEKO filter housings that accept the FE851AC cartridge. The element captures oil aerosol and water mist carried over from the compressor and the piping, holding it in the media until the droplets combine and drain, rather than passing it along to the tools and processes downstream. BEKO uses the trailing letters to distinguish media builds within the same body. The 851 size is offered as AC, X1 and XA versions that are physically interchangeable but not functionally equivalent, so order to the code on the cartridge you removed. Our full range of coalescing air filters can help you confirm what a given housing was built to take. Oil aerosol that gets past a coalescing stage tends to end up coating heat exchangers and adsorbent beds further down the line. Changing the element on schedule is the cheapest way to protect an investment in compressed air dryers and the finished work they support. 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: KPE851AC
