Description
Within the Walker A Series range, the WF821YO is the Ultramax Systems replacement element. As a Grade YO high efficiency oil removal coalescing element it strips fine oil aerosol and water carryover, rated at 0.1 µm. The element belongs downstream of a general purpose coalescing stage. This is the stage that decides how much oil reaches the point of use. The element is built to the original dimensions and needs no modification to the housing. Australian stock holding keeps lead times short, at a working budget price relative to the OEM part.
This replacement filter element from Ultramax is a high-quality, Walker A Series-compatible alternative. Designed as an alternative to OEM part numbers E821RXA E821 RXA EWK821RXA EWK821RXA-FAPE APW821RXA OWAE821RXA/SAl WALKER FILTRATION E821RXA. It is engineered to suit a wide range of filter housings.
