Parker Hannifin 402291 WNE0100A Water Separator

The Parker Hannifin 402291 WNE0100A Water Separator is an inline filtration device engineered to remove free water from fluid lines, protecting hydraulic and related systems from moisture contamination. Identified by Parker part number 402291 and the WNE0100A designation, this unit represents a specific water-separation component within Parker’s filtration lineup. By capturing water before it reaches downstream components, the separator helps reduce the risk of corrosion, ice formation in cold environments, and lubricant degradation, supporting longer service life for pumps, valves, and actuators. Designed for inline installation in the fluid path, it enables maintenance of fluid purity and reliable system performance in applications where moisture control is critical. For successful integration, verify compatibility with the system’s fluid type and flow requirements and follow Parker’s installation practices for inline water separation. This part is applicable in hydraulic, lubrication, and fuel circuits where moisture management is essential to ensure consistent operation and system reliability.
