Description
The NF51090PS is the Ultramax Systems replacement element for the National AF range. As a Grade PS replacement filter element it holds the contamination its housing is placed to catch, rated at 15 µm. It sits in the position the original element occupied. Catching the coarse load here keeps the coalescing stages from blinding early. Dimensions follow the original, so it installs into the existing housing without modification. Housings in the AF0946B 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 51090B15. It is engineered to suit housing models AF0946B. Manufactured to strict quality standards, it delivers reliable system protection at a competitive price.
