RSI's patented systems use the vacuum from the engine's intake manifold to extract the soil vapors.

Air flow rate is governed by the cubic inch displacement of the engine, rpm, system load, and site specific conditions. For large sites with multiple wells, positive displacement blower(s) driven by the ICE can provide extraction flow rates up to 2,300 SCFM.

Blower capacity in terms of total flow and vacuum pressure can be sized to meet each specific remediation design. For sites requiring higher vacuum (greater than 18" Hg), liquid ring vacuum pumps can be driven by the ICE. The ability to deliver up to 156 brake horse power with the eight cylinder engine allows us to meet every customer need.
