{"product_id":"castair-d10324hc2-s","title":"Castair D10324HC2-S","description":"\u003cp\u003eThe Castair D10324HC2-S is a 20 total horsepower duplex two-stage air compressor on a 240-gallon horizontal ASME tank, wired for three-phase electricity. It uses the HC2 pump at 758 RPM, delivers 70 CFM at 175 PSI combined, and weighs 1,760 lbs. Dimensions are 85\" x 30\" x 64\". The magnetic starter is factory mounted and wired. This unit combines three-phase efficiency with maximum storage capacity at the HC2 pump speed — the right choice when you have three-phase service, need the output of dual 10 HP pumps, and want the largest standard tank in the 2x10HP three-phase lineup.\u003c\/p\u003e\n\n\u003ch2\u003e240-Gallon Tank: When Storage Matters\u003c\/h2\u003e\n\u003cp\u003eThe 240-gallon receiver on the D10324HC2-S versus the 120-gallon on the D10312HC2-S is not just about having more air on tap — it is about duty cycle management. A larger tank means:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFewer pump start\/stop cycles per hour, reducing motor start stress and wear\u003c\/li\u003e\n\u003cli\u003eMore stable supply
