Phase 3:
Phase Three is the most important phase in meeting specific cleanliness codes. Unlike the pre-filter, the fine filters typically
use absolute rated media. Absolute filters have a very high efficiency and will ensure that fuel leaving the system is clean to
specification and has a low water content. Like previously mentioned, pre-filtering should be performed to remove any large
particulate, water, and sludge. Pre-filtering will extend the life of the fine filters.
1. Connect the Discharge Hose to the Discharge Port (after fine filters).
2. Ensure catridge filters are in the first and/or second stage of final filter vessels.
3. Increase pump motor speed as appropriate to continue fuel polishing and fuel restoration process.
4. Limit motor overspeed operations to light load conditions. Motor over speed is when the speed indicator window
indicates greater than the nominal 60 Hz. 60 Hz is the normal “rated RPM speed” of the motor. At 60 Hz, (displayed in
the Speed Indicator Window) Flow Rate will be approximately 300 GPM (attainable with new/lightly loaded filters).
5. Monitor process and change bag filters and filter elements as necessary.
6. Bag filter vessel is equipped with a vacuum gauges. Final filter vessels have pressure gauges to show the pressure
condition of the pump. Differential gauges are installed to show the pressure drop over each filter individually.
7. Now is the time to add AXI International AFC-710 Fuel Catalyst in a dose of 1 : 2500 or 1 gal of AFC-710 for 2500 gallons
of fuel. Higher doses of AFC-710 may be necessary depending on condition of fuel.
Note: System can run with fine filters in one, two, or none of the final filter vessels. This allows for phasing of the fuel
cleaning process
Note: Pre-filter should always have some type of pre-filter bad in place during operation to extend life of the pump vanes.
