Overview

EcoFlow Control pinch drainage uses a flexible membrane to regulate outflow independent of water level. Steep characteristic curve delivers a near-constant drain rate and over 80% efficiency versus static throttles — often reducing required retention volume. Available for Carat XL/XXL, Platin XL/XXL, and Vario 800 shaft systems. Source: graf.info/en/retention/ecoflow-control-pinch-drainage.html
