Downstream Defender®

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.

Downstream Defender®

The Downstream Defender's innovative design delivers high efficiency across a wide range of flows in a much smaller footprint than convential or other swirl-type devices. It is the perfect choice for any catchment likely to convey high quantities of contamination.
