This activated carbon adsorber element is designed as an equivalent replacement for the Hitachi HKF-55B filter element. It installs as the final polishing stage inside a compressed air filter housing, downstream of coalescing filtration, where a bed of activated carbon adsorbs the oil vapor, hydrocarbons, and odors that particulate and coalescing filters leave behind.Offered among our carbon and oil-vapor filter elements, it helps an existing filter housing keep performing like new and works alongside the rest of our compressed air filters. Changing the element on schedule supports clean, odor-free compressed air and protects downstream equipment and point-of-use processes.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: FHKF55AC-AB
