Description
The WF139Y covers the Walker Alpha OLD + Sterile range in the Ultramax Systems alternative line. As a Grade Y high efficiency oil removal coalescing element it strips the fine oil aerosol and water carryover a general purpose stage leaves behind, rated at 0.01 µm. It sits directly downstream of a Grade X stage. Air leaving this stage is clean enough for instrument work and for a carbon tower to polish. Dimensions follow the original, so it installs into the existing housing without modification. It is the element used in A391XA housings. Stock is held in Australia and supplied at a working budget price against going direct to the OEM.
This replacement filter element from Ultramax is a high-quality, Walker Filtration Alpha Series-compatible alternative. Designed as an alternative to OEM part numbers E139XA EWK139H OWAAE1139XA/S APW139F EWK139H-WAAE Walker Filtration E139XA Walker Filter E139XA. It is engineered to suit housing models A391XA. Manufactured to strict quality standards, it delivers reliable system protection at a competitive price.
