Box 2783, Denton, TX 76202 | (940) 382-3814 | pwp@pwgazette.comThe 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 = (πr²)h.
1 cubic inches = 0.000578703704 cubic feet.
All Softening cartridge can be regenerated by soaking them in a salt solution, information on regenerating softening cartdges can be found here
