Equivalent coalescing element for BOTTARINI part number 223081, built to the same fit and function as the original cartridge. It merges the fine oil and water aerosols carried in the compressed air into droplets that drop out of the flow and collect in the filter bowl. Getting the aerosol out early protects everything behind the filter. Dryer media, pneumatic valves and cylinders, and any finish work at the point of use all last longer on air that has passed through a coalescing stage in good condition. Our coalescing filters and elements range spans many housings and grades, and complete coalescing air filters are available if the housing needs replacing too. Order to the code on the element you are removing. 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: KP315-009
