Servicing Fine Filter(s)
There are two types of AXI International fine filters available.
1. 2 to 30 micron high efficiency particulate filter
2. 5 to 30 micron water block fine filter
The AXI International Water Block removes entrained and emulsified water from fuel and oil.
Changing Filters:
Pending all butterfly valves are open, a differential pressure drop of 22 PSI, as shown by the differential pressure gauges on
the final filters, indicates that the final filter elements of that vessel need to be changed.
1. It will be necessary to purge as much fuel as possible from the final filter vessels.
2. Close the inlet valves on the pre-filter to prevent more fuel from entering the system.
3. Open the bleeder valve on top of each primary filter to allow air into the system.
4. Turn on the Smart Filtration Controller using the breakers to power the Variable Frequency Controller.
5. Turn on the pump to remove the fuel in the system until the suction hose is empty.
6. Turn off the pump.
7. Fuel level in final filters should be sufficiently low to change the elements.
8. Remove dirty elements and replace with correct elements for the application.
9. Open the vent valves on the final filter vessels to release any remaining pressure. Open lids and replace.
10. Apply a film of lubricating oil to the lid gasket. Replace O-Ring if worn or damaged.
11. Tighten lid screws evenly (alternating the screws) to ensure lid is fully seated onto O-Ring gasket.
12. Close primary and final filter vent valves.
13. Open inlet valves on system skid.
14. Resume pump operation and check for leaks.
Note: All filters within each filter vessel should be identical.
The material trapped inside the filter can be inspected to better understand the types of contaminants that have been
removed from the tank.
Note: Disposal of fuel, associated waste, and filters must be in accordance with all applicable Federal, State, and Local
rules, laws, standards, and regulations.
