Disposable Hydraulic Filter Element - 190 L/min Flow, 21 MPa Collapse Pressure, Filtration Ratio = 75 at 7 μm
J2321/2
This specification sheet establishes requirements for a high collapse pressure configuration filter element of a specific configuration with a minimum filtration ratio of 75 for particles larger than 7 µm when designed and tested in accordance with SAE J2321 and this specification sheet.
Rationale: This document is proposed to be updated to provide supplemental requirements and test methods for the development, and test of a robust filter element design for use in Size B filter housings MIL-DTL-24402 or earlier revisions. A robust filter element is to be defined as a filter element capable of maintaining specified filtration efficiencies both at rated flow and under prescribed, dynamic flow conditions.
