Precision Accu-Flo Landfill Gas Wellheads

QED Accu-Flo wellheads can help prevent landfill gas migration, emissions and subsurface fires. Landfill owners and operators will appreciate the Accu-Flo design that meets the special requirements of landfill gas recovery for environmental compliance and energy production. Designed to rotate freely in two planes, the Accu-Flo wellhead will adapt to changes in terrain as your landfill shifts and subsides. Easy installation and maintenance of the Accu-Flo wellheads help to maximize gas recovery while minimizing surface emissions and subsurface migration. The pitot tube wellhead design is available with a standard gate valve or with our Exact-Flo control valve. The Accu-Flo wellhead features quick-connect measurement ports designed to work most efficiently with our GEM gas analyzers.
