Remediation Solutions - Soil Venting

Oak Environmental's regenerative vacuum/blower units (VAC-R) are carefully designed for today's soil venting requirements. These quiet and dependable VAC-R units are ideally suited for use in sensitive areas where in-situ treatment is preferred. We have VAC-R units for:

  • vapour extraction
  • soil remediation
  • landfill degassing
  • aeration
  • radon removal
  • bio-remediation

VAC-R unit features:

  • Rugged industrial-duty type, designed for continuous operation
  • Impeller, housing, cover and manifold cavity are manufactured from aluminum alloy, inherently resistant to corrosion and sparking
  • VAC-R units are CSA-approved for hazardous location operation


  • Extract or control vapours, reducing or preventing migration into sensitive areas
  • Control or recover fugitive hydrocarbons at leak sites
  • Assist in early leak detection so product losses may be detected and controlled
  • Monitor the effectiveness of remedial measures being taken
  • Provide oxygen enhancement for bio-remediation
  • Aerate sludges or liquids
