STS 7040 Programmable Automated Fuel Filtration Systems are self-contained, stand-alone systems that remove and prevent the buildup of water, sludge and contaminants in tanks, and condition the fuel. They are designed to optimize and maintain diesel fuel indefinitely, stabilize diesel and bio-fuels, eliminate microbial contamination to optimize and maintain fuel quality. Trust our STS systems for Optimal Fuel Quality and Reliable Power at All Times.
All STS 7040 Series feature:
Multi-stage water removal and particulate filtration
NEMA 12, 13, 3R, 4 Powder Coated or Stainless Steel Cabinet Enclosure
UL508A Smart Filtration Controller
Continuous-Duty Pump, Viton Seals
Stainless Steel Plumbing
Stand-Alone, Reliable & Turn-Key
Implementing STS Fuel Quality Optimization & Maintenance Systems provides Optimal Fuel Quality for Reliable Power At All Times. STS 7000 Series Systems prevent downtime, periodic tank cleaning, replacing out-of-spec fuel and fuel-quality related injection system repairs.
The STS 7000 Series is equipped with a UL508A Touch-Screen Controller with Modbus, TCP/IP, LAN and Internet connectivity for more intuitive system setup and monitoring from remote locations.
For safe operation, the STS 7040 Series’ touch-screen controller triggers automatic alarms and shuts down the pump when filters need service, a leak is detected, high final filter water level, high filter vacuum or high pump pressure occurs, or when the fuel flow is out of range.

Fuel is inherently unstable. It naturally forms sediments, solids and tank sludge. Clogged filters, smoke and damage to injection systems are often symptoms of less than optimal fuel quality causing engines to be unreliable, smoke, lose power and ultimately fail. Water naturally accumulates in storage tanks due to condensation or leaks in fills and vents. Water and temperature changes create an environment for microbial growth and natural oxidation, accelerating formation of sludge, acids and tank corrosion.
Preventive Maintenance Plans for mission-critical power are essential. However, most service agreements do not cover fuel-related engine failures. Fuel has a limited shelf-life and even “fresh fuel” could contain water, sediment, microbes and bio-fuel components upon delivery.
Periodic generator test-runs are too short to determine if fuel quality is adequate for the demands of continuous, full-load operation. In fact, generator test runs significantly accelerate the fuel polymerization and degradation process by returning fuel that has been compromised by heat and pressure back to the tank.
Potential liabilities can easily be avoided by implementing an AXI Fuel Quality Maintenance Program as part of every disaster recovery plan. An STS 7000 Series Programmable Automated Fuel Filtration System automatically maintains fuel quality and guarantees reliable emergency power whenever it is needed.
The system is automatically operated by the programmable UL508A Touch-Screen Controller with Modbus, TCP/IP, LAN and Internet connectivity. All components and control devices are contained within a fully enclosed, lockable, weatherproof, NEMA-rated cabinet.
The principal components are a continuous-duty motor with coupled gear pump, a Y-strainer removes unexpected debris that can damage downstream components. The mechanical water separator, utilizing Specific Gravity Separation, removes water and particulates. Fuel is pulled into the Internal Gear Pump, through a vacuum switch and gauge, and out through a pressure switch and gauge. Fuel then passes through the AXI Inline Fuel Conditioner and on through the Primary/Final screw-on particulate filters (two configured in parallel) and on to the Secondary/Final screw-on Water Block fine filters (two configured in parallel) with pressure gauge and Flow Switch sensor and Sight Glass. The patented AXI Fuel Conditioner prevents and reverses fuel degradation, agglomerization and microbial contamination. The four secondary filters are spin-on filters designed to remove dissolved and emulsified water and contaminants down to 1 µ.
The optional Automatic Water Drain provides automatic water removal from the Primary Filter/water separator. Three Watect Water Level Sensors control the water drain pump and also provide emergency system shutdown in the event of a component default. An inline strainer is incorporated to protect the water removal pump. A 30-gallon waste water drum with removable lid and EPDM gasket is included. The drum is made of translucent 3/16" polyethylene to show the level of waste water in the drum. A water level float switch is installed in the drum to assure the waste water drum does not over-fill.
For safe operation the STS 7000 Series is equipped with a drip tray monitored by a leak detector. Additional safety elements include automatic system shut-down and indicators when filter elements require service, high pump vacuum exists or a flow interruption is detected.
Fuel Maintenance is an important part of periodic generator maintenance programs – just like changing the oil and ensuring the batteries are charged.
AFC provides superior fuel quality for engines and storage tanks - lowering operating costs, maintenance, and downtime. AFC-705 accelerates tank cleaning and fuel restoration processes by cleaning heavily contaminated fuel systems and storage tanks. It dissolves tank sludge, stabilizes the fuel, restores Optimal Fuel Quality, and preserves the integrity of stored fuel up to 12 months.
When AFC is added to storage tanks with each refueling, it enhances combustion, eliminates carbon deposits, reduces harmful emissions, and lowers fuel consumption an all downstream power plants into which the fuel is transferred. AFC is an integral part of an ongoing regimen that will keep fuel tanks clean, free of water, and fuel in optimal quality.
AFC-710 Fuel Catalystis formulated to be Tier 4 Complaint for use with engines manufactured in 2007 and later. AFC-710 has a chemical affinity to the hydrocarbons in your diesel fuel, helping your engine tap into your fuel’s full potential by burning it more completely. While it is doing so, it’s also cleaning out your fuel system from the fuel tank, to your injectors, to your combustion chamber, and through to your exhaust.
AFC-705 Fuel Catalyst is a unique and powerful broad-spectrum fuel additive concentrate for use in Diesel, Biofuels, Gasoline, Kerosene, and HFO. Including AFC-705 as part of a preventative fuel maintenance program, in combination with good housekeeping, will stabilize your fuel, prevent sludge build-up, and eliminate the need for expensive and toxic biocides. Trust AFC-705 Fuel Catalyst to help ensure Optimal Fuel Quality at All Times. Using AFC-705 accelerates tank cleaning and the fuel restoration process. It enhances the breakdown and removal of sludge, slime, and bio-fouling from tank walls and baffles that are difficult to access. AFC-705 effectively decontaminates and cleans the entire fuel and injection system. It continues to work in storage tanks cleaning and stabilizing fuel for 6 months or longer.
Using AFC with one of AXI's fuel treatment systems, such as the STS7040 system, will loosen and begin the process of dissolving the debris, clean microbial and fungal growth from tank walls, top and bottom, and speed the return of fuel to optimal fuel quality.
