Standby Generator Fuel Conditioner - STS 7004 Automated Fuel Filtration Systems from Algae-X International

STS 7004

The STS 7004 Automated Fuel Filtration Systems are self contained, stand-alone and fully automated. 


  • recondition and stabilize fuel
  • eliminate and prevent microbial contamination
  • remove water, sludge and contaminants from tanks
  • preserving the integrity of stored fuel
  • providing reliable power whenever it is needed


Three- or four-stage water removal and particulate filtration down to 3 micron Patented Fuel Conditioner reverses fuel deterioration and polymerization to submicron levels.

Technical Specs 

The STS 7004 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, E-mail and SMS Maintenance Alerts, Maintenance Alert Log File and On-screen Help. For safe operation, the Touch-Screen Controller triggers automatic alarms and shuts down the pumpwhen filters need service; a leak is detected; high separator water level, high filter vacuum, or high pump pressure occurs; or when the fuel flow is out of range. In addition to the features of the industry standard STS-6000 Series, the STS 7004 includes Multiple-tank Functionality.

Fully automated programmable control Automatic shut-down for high vacuum, filter pressure, leak and flow interruption detection Integrated industrial display and control panel Easy installation independent of genset ("kidney loop") Stand alone, safe, reliable, turn key solution

The principal components are a continuous duty motor with coupled gear pump, strainer/primary filter with vacuum sensor and gauge, Algae-X Fuel Conditioner, and a secondary filter with pressure gauge and sensor. The system is automatically operated by the programmable, UL 508A listed Algae-X Smart Filtration Controller. All components and control devices are contained within a fully enclosed, lockable, weatherproof NEMA 3R cabinet.

The strainer/primary filter protects the pump and removes water and particulate. Please specify "–S" for the optional Separ primary filter with water sensor alarm. The secondary filter is a quick change spin-on filter designed to remove emulsified water and contaminants down to 3 Micron.

For safe operation the STS 6000 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.
