Description
Within the Walker A Series range, the WF731YO 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. 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. Held in Australian stock, it is supplied at a working budget price rather than OEM list.
This replacement filter element from Ultramax is a high-quality, Walker A Series-compatible alternative. Designed as an alternative to OEM part numbers E731RXA E731 RXA EWK731RXA EWK731RXA-FAPE APW731RXA OWAE731RXA/SAl WALKER FILTRATION E731RXA. It is engineered to suit a wide range of filter housings. Manufactured to strict quality standards, it delivers reliable system protection at a competitive price.
