{"product_id":"castair-d10124hc3-s","title":"Castair D10124HC3-S","description":"\u003cp\u003eThe Castair D10124HC3-S is a 20 total horsepower duplex two-stage air compressor combining the largest standard tank in the single-phase 2x10HP lineup (240 gallons horizontal) with the slower-running HC3 pump (570 RPM). It delivers 70 CFM at 175 PSI combined, weighs 2,150 lbs, and measures 94\" x 30\" x 64\". This is the top configuration in the single-phase 2x10HP family — maximum tank storage, slowest pump RPM, lowest operating temperature, and quietest operation of the four single-phase variants.\u003c\/p\u003e\n\n\u003ch2\u003eWho This Unit Is For\u003c\/h2\u003e\n\u003cp\u003eThe D10124HC3-S is specified by shops that run the compressor hard, continuously, and need it to hold up over years of heavy use. The combination of 240-gallon storage and 570 RPM HC3 pump means:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFewer pump start\/stop cycles per shift due to the large tank buffer\u003c\/li\u003e\n\u003cli\u003eLower pump operating temperature due to slow RPM, extending valve and ring life\u003c\/li\u003e\n\u003cli\u003eQuieter operation than an equivalent 758 RPM HC2 unit\u003c\/li\u003e\n\u003cli\u003eDuplex redundancy — one pump keeps the shop running if the other needs service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou are paying for the largest, most durable configuration in this power class. If your shop runs spray painting, plasma cutting, sandblasting, or has multiple simultaneous air tool users, this is the appropriate specification.\u003c\/p\u003e\n\n\u003ch3\u003ePump and Motor

High-utilization shops on single-phase power, long-cycle processes (collision painting, sandblasting, CNC machining), shops where noise level matters and floor space accommodates a 94\" x 30\" footprint, and anywhere the compressor will run 6-8+ hours per day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStep down to D10124HC2-S\u003c\/strong\u003e if noise and pump temperature are not primary concerns — same tank, same output, 330 lbs lighter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStep down to D10112HC3-S\u003c\/strong\u003e if your peak demand does not exhaust a
