Automatic Fuel Oil Filtration Sets

Our Automatic Fuel Oil Filtration Sets are the most complete, efficient and reliable engine protection systems you can install.  These self-contained, fully automatic systems remove water, suspended rust, dirt and other contaminants in order to maintain the quality and purity of stored diesel fuel.

  • Standard flows from 180 to 1200 GPH
  • Custom units for processing 50 gallon per minute or more.
  • Cleans and de-waters fuel with:
     - Nearly 100% water removal
     - 99% particulate removal (to 5 micron)

Water enters fuel systems through vents, leaks, and sometimes with the delivered fuel. Microorganisms can grow in fuel, especially in the presence of moisture. The resulting sludge left in the system can cause tank, fuel line, strainer, pump and engine injectors to clog. Water induced corrosion (rusting) can reduce tank life expectancy and reliability of the emergency diesel generator or boiler.

The Model PF Automatic Fuel Oil Filtration Set combines  microprocessor-based control and monitoring with a “five stage” fuel oil de-watering and cleaning process:

1. Fuel Straining: Large contaminates are removed
2. Filtration: Fuel filtration to 5 micron
3. Water Removal: Removes water through special filter design.

The separated contaminants and water are monitored by an integral filter water level detector. Depending on the size of the system, this waste water is piped to an optional Waste Water Holding & Removal System or connected directly to the customer's waste tank (by others). A differential pressure switch/indicator is installed around the filter units to provide a visual indication of filter element condition. An alarm notifies plant personnel when the filter elements require replacement.

  • Standard flows from 180 to 1200 GPH
  • Cleans and de-waters fuel with:
     - Nearly 100% water removal
     - 99% particulate removal (to 5 micron)
  • Automatic cycling based on the time of day and the day of the week ensures continuous fuel maintenance
  • Alarm and Safety Shutdown for filter water level “High”, filter “Saturated”, system base “Leak” detected
  • Microprocessor-based
  • Factory mounted and wired control cabinet
  • NEMA 4 cabinet (Standard)
  • Biodiesel compatible

Preferred Model PF automatic filtration systems are designed for diesel fuel oil facilities that do not normally consume enough fuel to keep the diesel "fresh". This includes emergency generators, dual fuel hospital boilers that normally fire natural gas, emergency pumping stations, and emergency response centers.


Five sizes are available from 180 GPH to 1200 GPH. Options include a skid-mounted waste water removal and holding system, and a chemical additive storage and injection system.
