SYSTEM SELECTION GUIDE
Note: System options do not cover all conceivable/acceptable variations. They are listed here as a general guideline to show
the most common type arrangement for multiple systems. Based on certain system designs utilizing manifolding, non-manifolding,
3-tank systems, etc., other tank/cartridge combinations can be designed. The combinations below are based on 11 flow, 3 gallon tanks
and 5 flow, 1.5 gallon tanks. More competitive designs may be available by utilizing 12 flow and 6 flow systems when appropriate.

* Based on 5 flow numbers for a 1.5 gal system and 11 flow numbers for a 3 gal. system.
** If tanks are manifolded, only a “double tank” nitrogen cartridge (Part No. 423493) can be used.
*** If tanks are manifolded, either an LT-A-101-30 nitrogen cartridge (Part No. 423491) or a double tank cartridge (Part No. 423493) can be used.
