Gravity Fuel System
Calculate Your SOLO Savings
See exactly how much you'll save by switching to the Gravity SOLO model — no technician required, no inflated day rates.
Reduce Fuel System Costs Without Compromising Operations
Conventional AFS systems often depend on higher equipment costs, technician-supported operation, and more moving parts. Gravity’s SOLO model helps remove the largest recurring cost from the equation: the dedicated on-site technician.
With a lower day rate and a simpler system architecture, Gravity helps operators reduce monthly fueling costs while maintaining consistent fuel delivery across demanding frac environments.
Why Operators Switch To Gravity
Operators choose Gravity because it helps reduce AFS cost and operational complexity at the same time.
Lower Cost
Gravity SOLO can save approximately $30,000 per month per pad by reducing technician-dependent fueling cost.
Simpler Operation
Gravity uses a patented gravity-fed delivery valve instead of relying on pumps, motors, or complex fuel-moving electronics.
Field-Proven Reliability
Gravity is built for demanding frac environments where fueling interruptions can create downtime, cost exposure, and unnecessary operational drag.
Automated Fuel Delivery With No Pumps Or Motors
Gravity uses a patented gravity-fed delivery valve that responds to tank pressure and helps maintain fuel levels automatically. Because the system does not rely on pumps, motors, or complex electronics for fuel movement, operators gain a simpler and more reliable way to keep frac equipment fueled.
One Gravity Unit Can Do The Work Of Two Competitor Units
Simulfrac operations are growing across major U.S. plays, but many AFS systems require two units to support the job. Gravity is built to handle Simulfrac fueling with a single unit, helping operators avoid unnecessary equipment cost and reduce operational complexity.
For operators running Simulfrac programs, Gravity helps improve pad economics by reducing the number of AFS units required on location.
Low-Pressure Fuel Delivery By Design
Gravity delivers fuel at approximately 7 PSI, which is well below the pressure levels that can create hose spray and turbocharger fire risk in conventional systems. The double-wall flame shield tank and integrated spill containment reinforce a safety-first system architecture.
Gravity is not a pump-based AFS with safety features added later. It is a fundamentally different fueling system built around low-pressure, gravity-fed delivery.
A Field-Proven AFS Built For Demanding Frac Operations
Gravity has proven itself across demanding operating environments, including more than six years of SOLO operation in the Middle East with zero on-site technician support. Fewer moving parts, simpler rig-up, and lower maintenance needs make Gravity a practical choice for operators who need reliable fueling without added operational drag.
