Combined output is 123.4 CFM at 0 PSI and 100.4 CFM at 175 PSI. At $9,173, this is the maximum storage and maximum CFM combination for the 15 HP tandem series. If you are running a body shop where two painters are spraying simultaneously, a production facility with sustained air tool demand across multiple stations, or a tire and service shop with high throughput, this configuration gives you 100+ CFM sustained at 175 PSI with 240 gallons of buffer to ride out demand spikes without pressure drop.\u003c\/p\u003e\n\n\u003ch3\u003eWhy the HC2 Pump on a 240-Gallon Tank?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum CFM output:\u003c\/strong\u003e The HC2 pump is the larger, slower configuration. At 795 RPM, each pump displaces more air per revolution than the HC1 at 898 RPM. Combined, the two HC2 pumps deliver 123.4 CFM — over 13 CFM more than the HC1 tandem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum storage:\u003c\/strong\u003e The 240-gallon receiver holds twice the stored air of the 120-gallon tank at the same pressure. Demand spikes that would drop a smaller tank's pressure by 30–40 PSI barely register on a 240-gallon system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhen to spend the extra money:\u003c\/strong\u003e If you consistently run at or near 90 CFM sustained (the HC1's limit at 175 PSI) and your system pressure fluctuates more than you would like, the T15324HC2-S resolves both problems at once.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCast Iron Pump Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll cast iron construction:\u003c\/strong\u003e Cylinders, heads, and crankcase.
