Product details

Key construction, installation and performance notes for EcoLoop Sapphire Hydrodynamic Separator.

Overview

EcoLoop Sapphire (Saphir) is a hydrodynamic separator for stormwater pre-treatment per DWA-A 102-2. Nature-inspired inlet geometry reduces turbulence for optimised tangential inflow; a two-chamber layout with an integrated flow separator delivers reliable retention of filterable solids (AFS) — confirmed by independent PIA Aachen laboratory testing (AFS63). Use ahead of surface-water discharge or upstream of a retention facility. Compact, pre-assembled with inlet/outlet pipe, no height offset between connections, easy maintenance access. Truck loading possible with a truck-rated cover plus load-distribution plate. Covers ordered separately. Source: graf.info EcoLoop Saphir.
