Description
Ultramax Systems supplies the NF51090YO as a direct replacement within the National AF range. The element is a Grade YO high efficiency oil removal coalescing element, and strips fine oil aerosol and water carryover, rated at 0.1 µm. It sits downstream of a general purpose coalescing stage. This is the stage that decides how much oil reaches the point of use. Dimensions follow the original, so it installs into the existing housing without modification. Housings in the AF0946M family take this element. 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, National Filters AF Series-compatible alternative. Designed as an alternative to OEM part numbers 51090M 51090M-1 51090-XM National Filters 51090XM. It is engineered to suit housing models AF0946M. Manufactured to strict quality standards, it delivers reliable system protection at a competitive price.
