How the EvacuSol Soil Vapour Extraction System Works

ERE's EvacuSol Vapor Extraction Systems are designed for soil degassing and ventilation applications that require low-flow / high-vacuum capabilities. The system is applicable to the removal of volatile and semi-volatile organic compounds from the vadose zone. Vapors drawn are carried through vent ductwork to the outside atmosphere or a vapor treatment system.

Each unit is built around a regenerative blower with inlet / outlet plumbing, an air filter, an ambient air valve, vacuum gauges, a power disconnect and a thermal overload protection switch. Units are UL and CSA approved, conform to NEMA frame sizes, and are Explosion Proof, Division 1 & 2, Class 1 for Group D hazardous atmospheres.

Key Specifications

Options

• EvacuSol™ Reverse Manifold — converts an extraction well into a sparging point. Ideal for push-pull applications on the same well; includes a three-way valve assembly that converts an extraction well into a sparging point without any pipe change.
• Tornado™ Moisture Knock Out Unit — protects regenerative blowers from corrosion and mineralization damage. Uses high-efficiency cyclonic action with a check-ball system that prevents water entering the vacuum blower.
• EvacuSol™ Storage Aluminum Box — suits systems up to 2 HP; rugged aluminum construction with lifting handles, lockable, rubber isolator feet.
