Publication number: 20230023624Abstract: A filter cartridge with flow travelling from inside to outside with a flow path in a bottom end cap to enter the cartridge has an anti-drain back valve to prevent cross-contamination to the clean side of the system during filter change-out. The anti-drain back valve moves away from the bottom end cap to allow inlet flow into the cartridge during filtering operation, and when flow ceases, the valve settles to the bottom of the cartridge to plug the flow path during service.Type: ApplicationFiled: July 12, 2022Publication date: January 26, 2023Inventors: Michael J.
