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 and other high-demand frac environments. Many AFS systems require two units to support the job. Gravity is built to support high-demand Simulfrac and Dual Frac fueling with a single unit, helping operators reduce equipment count, lower cost, simplify location layout, and improve pad economics.
Low-Pressure Fuel Delivery By Design
Gravity uses a patented delivery valve that responds to tank pressure and helps maintain fuel levels automatically. The system supports automatic fuel delivery without relying on pumps, motors, or complex electronics for fuel movement.
For cost-focused operators, that means less field support burden. For remote operators, that means fewer mechanical components that can fail. For every market, it means a simpler automatic fuel system built for consistent frac equipment fueling.
Continuous Fueling Without Interrupting Operations
Gravity supports continuous hot-fueling of frac pumps and associated equipment while operations are running. The system is designed to help maintain fuel supply during active pumping operations without forcing unnecessary interruptions for refueling.
That helps operators keep equipment running, reduce refueling-related downtime, and support continuous frac activity across demanding field conditions.
Low-Pressure Fuel Delivery Built For Safer Field Operation
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 different fueling system built around low-pressure, gravity-fed delivery.
