Equivalent coalescing filter element replacing Bottarini 223075. The media is built in depth rather than as a surface screen, so fine oil and water aerosol is captured through the thickness of the element and released as drained liquid. Element codes on this kind of part describe the media build, not just the size. Two elements that drop into the same housing can be graded very differently, which is why the number on the cartridge is the thing to order from, and why guessing from the housing label tends to go wrong. The full element range is grouped under coalescing filters and elements, with the complete housings listed separately 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: KP185-036
