Equivalent coalescing element for BOTTARINI part number F007A, built to match the original cartridge for fit and function. It pulls the fine oil and water aerosol out of the compressed air stream, coalescing it into drops heavy enough to fall clear of the flow. If an element is loading much faster than the last one did, the filter is usually reporting a problem rather than causing it. Bulk oil carryover from the compressor is the most common upstream culprit worth ruling out. Browse coalescing filters and elements for the rest of this family, and check the air oil separator range if the compressor itself is passing oil. Order to the code printed on the element. 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: KP66-020
