CECCATO/MARK 1617719202 is a compressed air filter element, and this listing covers an equivalent replacement. The element is the working part of the filter assembly, the media through which the air actually passes, and it is what determines how much oil and moisture makes it past the housing. Because it is a consumable, it makes sense to order media with the rest of the annual service kit rather than one at a time. Keeping a spare on the shelf means a loaded element gets changed the day it is noticed, not the week the replacement arrives, and the air quality your process depends on never drifts in the meantime. Our coalescing filters and elements range covers equivalents across many brands, and the air filters collection has particulate and general purpose media if you are servicing a full filter train. Send us the housing you are working on and we will confirm the fit. 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: KP55-007
