2025 Armtec Downstream Defender® 1,800 mm
The Downstream Defender® is an advanced vortex separator used to treat stormwater runoff in pretreatment or stand-alone applications. Its unique flow-modifying internal components distinguish the Downstream Defender® from conventional and simple swirl separators that typically bypass untreated peak flows to prevent washout of captured pollutants. The Downstream Defender® treats the entire storm with no washout or untreated bypass flows.
Features may include:
Environmental Protection- Captures and retains a wide range of Total Suspended Solids (TSS), floatable trash and petroleum products
- Accommodates change in outlet pipe direction without the need to construct a second manhole
- Treats the entire storm with no washout or untreated bypass flows
- Delivered to site as a precast concrete manhole chamber with pre-assembled internal components
