The cartridge uses hollow-fiber membrane technology, is field-maintainable with routine backflushing, and is sized to fit the AutoFlow XL series. It’s a compact, USA-made spare designed to be carried on extended trips or kept as a maintenance item at home.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will this cartridge restore my AutoFlow’s flow rate?\u003c\/h3\u003e\n\u003cp\u003eWhen installed and maintained with regular backflushing, the replacement cartridge brings the AutoFlow back to its designed flow performance—about 1.75 liters per minute under normal gravity conditions.
