Ensure stored fuel reliability with the FPS DX-S fuel maintenance system, a fully automated and programmable compact unit engineered for continuous removal of water, sludge, and particulate contamination from diesel and bio-fuel storage tanks. Driven by a continuous-duty DC gear pump with Viton seals at a nominal flow rate of 1.3 GPM (5 LPM), the system polishes stored fuel through a high-efficiency primary filter (10μ fine or 3μ water-block) and an LG-X 500 inline magnetic conditioner. The integrated Smart Filtration Controller provides programmable timer operation, leak detection, high pressure alarm, and automatic pump shutdown. Compact enough for installation inside gen-set enclosures, engine rooms, and confined indoor spaces, the FPS DX-S delivers round-the-clock automated fuel polishing where larger systems cannot fit.
The FPS DX-S is a purpose-built compact fuel maintenance system for facilities that require dependable, automated diesel and bio-fuel polishing within the footprint of a gen-set enclosure, engine room, or other confined indoor installation. Unlike portable polishing equipment, the FPS DX-S is designed for permanent wall mounting — operating unattended on a programmable schedule to remove water accumulation, sludge, and particulate contamination before it degrades fuel quality. Its continuous-duty DC gear pump with Viton seals circulates tank fuel through a high-efficiency primary filter (3μ water-block or 10μ fine) and an LG-X 500 inline magnetic conditioner. The Smart Filtration Controller ties everything together with programmable timer control, safety alarms, and automatic pump shutdown — giving operators a self-sufficient fuel polishing system that requires minimal day-to-day attention.
Specifications apply to the standard FPS DX-S fuel maintenance system. Primary filter options include 10μ fine filter (FFS-10) or 3μ water-block filter (WBS-3). Replacement basket strainer: TK-070 (50 mesh).

The FPS DX-S operates on a simple but highly effective closed-loop fuel polishing circuit. Once installed and plumbed to the storage tank, fuel is drawn from the lowest accessible point — where water and sludge naturally accumulate — through the 1/2″ inlet hose barb. The fuel first passes through the LG-X 500 inline magnetic conditioner, whose magnetic field breaks down and de‑clusters microscopic paraffinic and ferrous contaminants. This pre‑treatment improves the fuel's ability to shed water and reduces particulate re-agglomeration.
From the conditioner, fuel flows through the 50 mesh basket strainer to capture large debris, then enters the primary filter housing. Here, centrifugal action and the selected filter cartridge (3μ water‑block or 10μ fine) remove both solid particulates and free water. The cleaned fuel then passes to the continuous‑duty DC gear pump, which returns it to the storage tank via the outlet port, completing the polishing loop. A pressure switch on the pump discharge side continuously monitors for restrictions: if pressure reaches 15 PSI — indicating a clogged filter — the pump shuts down and triggers the high pressure alarm. The leak detection float switch in the drip tray similarly halts operation if a fuel leak is detected. The Smart Filtration Controller manages all timing and alarm resets, running up to eight programmed cycles per week with full memory retention during power outages.
The 10μ fine filter is a high-efficiency particulate filter, ideal for removing fine solid contaminants like rust, dirt, and sludge. The 3μ water-block filter is specifically designed to remove both solid particles and emulsified water from the fuel, making it the best choice for tanks known to have high water condensation or contamination.
The FPS DX-S is designed for diesel fuel and bio-diesel blends with a flash point at or above 100°F (37.8°C). It must NOT be used with gasoline or any other flammable liquid below this flash point threshold, as doing so creates an immediate fire and explosion hazard.
The system operates on 12VDC/10A or 24VDC/5A, allowing direct integration with generator control panels, DC distribution boards, or battery systems. The unit is wall-mounted, and all plumbing connections are 1/2″ hose barbs, making installation straightforward for qualified personnel.
The Smart Filtration Controller includes a high pressure alarm. When the primary filter becomes clogged and discharge pressure reaches 15 PSI, the controller automatically shuts down the pump and illuminates the alarm indicator. After replacing the filter element, reset the alarm via the controller panel to resume operation.
The LG-X 500 is a passive, maintenance‑free device that applies a strong magnetic field to the fuel stream. This field helps break down and de‑cluster microscopic paraffin and asphaltene molecules, improving fuel stability, reducing surface tension of water droplets for easier separation, and slowing sludge formation in the tank.
The FPS DX-S is intended exclusively for permanent indoor installation — it is not rated for outdoor or exposed environments. It should be wall-mounted on a hard, level surface inside a well-ventilated space with ambient temperature between 41 and 104°F (5 to 40°C). Its compact dimensions make it ideal for generator enclosures, marine engine rooms, and plant utility rooms.
