Parker-Watts EKF10Y Filter Element Kit, 40 Micron, B11 and B12 Integral Filter/Regulator

The EKF10Y is the 40 micron filter element replacement kit for Parker-Watts B11 and B12 general purpose integral filter/regulators. The filter half of those units is the F10 series, which is why the element carries an F10 prefix rather than a B-number. Key specifications Micron rating: 40 micron Filter type: Particulate and bulk water removal Kit type: Filter element replacement kit Fits: Watts B11 (knob adjust) and B12 (locknut or T-handle adjust) integral filter/regulators Threads: Dryseal pipe thread 5 micron option: EKF10VY, same units Related F10 service parts Parker service sheet IS-B11-B12 also lists the element retainer (F10Y49), the lower baffle (F10Y76) and the bowl O-rings (F10Y103-1 and F10Y103-2VT) for these units. If a bowl has been apart before, it is worth checking those at the same time as the element. Availability note EKF10Y is a legacy service part. It is covered by Parker's own B11/B12 instruction sheet but no longer appears in the current General Line or Prep-Air II catalogs, and new-series B11 filter/regulators take the Prep-Air II PS801 element instead. Check the label on your unit before ordering: if it is a new series B11, you want PS801, not EKF10Y. Applications Integral filter/regulators combine filtration and pressure control in one body, which is why they turn up on packaged equipment, OEM machine builds and compact air stations where panel space is short. Keeping the element on a change schedule holds the regulator's set pressure steady: a loaded element shows up first as a regulated pressure that sags under flow, long before anyone thinks to blame the filter. No product photograph is published for this element. The only images available from resellers are brand logos or watermarked, so we have left this listing without one rather than show you something that is not the part.
