This is a replacement coalescing element for domnick hunter compressed air filter housings that accept the K030AA cartridge. It is a like-for-like service part and does not include the housing or bowl. Changing a coalescing element is straightforward on most of these housings: isolate and vent the filter, unscrew the bowl, pull the spent cartridge, seat the new one and check the bowl seal before bringing the line back up. Venting first matters, because a bowl under pressure will not come loose safely. The rest of the size and grade lineup is listed under coalescing filters and elements, and the broader air filters section covers the housings and stages these elements belong to. 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: KPFEK025AAYE-CB
