The chart below expresses the theoretical performance capacity of our water softening cartridges in four sizes. It assumes the standard 32,000 grain per cubic foot capacity of new cation softening resin. Figures for regenerated resin are lower.

The chart is for information only and is not a guarantee of performance. Actual performance can be influenced by a number of variables.

Cartridge Size Actual Size of resin chamber Cu. Inch Capacity Cu. Ft. Capacity Gallons of 7 Grains Per Gallon Water Treated. Gallons of 15 Grains Per Gallon Water Treated. Gallons of 40 Grains Per Gallon Water Treated.
2.5" X 9.75" 2.75" X 7" 41.75 0.024 105 45 15
2.5" X 20" 2.75" X 17" 101.4 0.059 255 120 45
4.25" X 10" 4.25" X 7.5" 106.35 0.062 263 128 45
4.25" X 20" 4.25" X 17.5" 248.13 0.144 615 285 105

Deductions are made using the standard rules of cylinder volume:

The volume of a cylinder equals the (area of the base)*height = śr2h.
