240 GPM filters are used for which system, and what is their element configuration?

• A. Forward area refueling system / 5 coalescing elements and 2 separators
• B. Amphibious fueling system / 4 coalescing elements and 0 separators
• C. Tank and pump unit / 2 coalescing elements and 3 separators
• D. Advanced aviation forward area refueling system (AAFARS) / 3 coalescing elements and 1 separator element

Answer: (A)

The key idea is matching a high-flow fuel filtration needs with the right element configuration. For 240 GPM filters, the setup is designed to handle fast fuel transfer in forward operations, so it uses more coalescing elements to aggressively remove water from the fuel and enough separators to separate that water effectively before the fuel continues on. Five coalescing elements provide the capacity to coalesce small water droplets in a high-flow stream, while two separators remove the coalesced water and return clean fuel downstream. The other system options have different design needs and thus use different combinations of elements, not the 5 coalescing elements and 2 separators used here. So the 240 GPM filters are for the Forward Area Refueling System with five coalescing elements and two separators.
