Vertical tank orientation saves floor space — a 60-gallon vertical tank footprint is roughly half the floor area of an equivalent horizontal tank. At 35HP with a factory starter, you're getting a complete, ready-to-wire unit for high-production commercial and industrial environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpec note:\u003c\/strong\u003e Castair does not publish complete spec sheets for the C3516V60-S in their public tables. Data below is derived from model naming conventions and comparable C-series units. Contact us for confirmed CFM, RPM, and dimensional specs before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eVertical Tank — Practical Advantages\u003c\/h2\u003e\n\u003cp\u003eThe vertical tank on the C3516V60-S has a significantly smaller floor footprint than a horizontal 60-gallon tank. Typically a 60-gallon vertical tank runs 20-24 inches in diameter and 60-70 inches tall. In a busy shop where floor space competes with vehicle lifts, toolboxes, and work areas, this matters. The tradeoff is ceiling height — vertical tanks require adequate clearance above the unit for proper installation and service access to the pump.\u003c\/p\u003e\n\n\u003ch2\u003eCast Iron Pump and Two-Stage Compression\u003c\/h2\u003e\n\u003cp\u003eCastair builds all of their C-series compressors around all-cast-iron pumps running at slow RPM. Two-stage compression means the air passes through two compression stages — a large-bore low-pressure cylinder handles the initial compression to intermediate pressure, then a smaller high-pressure cylinder brings it to final working pressure. The result is more thermally efficient compression at pressures above 125 PSI, which is why Castair's two-stage commercial units are factory set to 175 PSI shutoff versus 125 PSI for their single-stage units.\u003c\/p\u003e\n\n\u003ch3\u003ePump Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll cast iron:\u003c\/strong\u003e Cylinders, heads, crankcase — no aluminum on the working components\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo-stage compression:\u003c\/strong\u003e Efficient operation at 175 PSI working pressure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlow RPM:\u003c\/strong\u003e Lower heat, longer valve and bearing life, quieter operation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered roller bearings:\u003c\/strong\u003e Both ends of the crankshaft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision steel connecting rods:\u003c\/strong\u003e Automotive-type rod bearings at crank, needle bearings at wrist pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc and spring valves:\u003c\/strong\u003e Serviceable, efficient, reliable under continuous operation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-ring pistons:\u003c\/strong\u003e Better sealing efficiency, less oil in the air stream\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentrifugal unloader:\u003c\/strong\u003e Load-less starts — motor reaches RPM before compression begins\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e60-Gallon Vertical ASME Tank\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVertical orientation:\u003c\/strong\u003e Compact floor footprint compared to horizontal equivalent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME-rated pressure vessel:\u003c\/strong\u003e Code-compliant for commercial\/industrial use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePowder coat exterior:\u003c\/strong\u003e Rust-resistant finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-leg base:\u003c\/strong\u003e Standard on Castair vertical tanks — stable, elevated for condensate access\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME safety valve:\u003c\/strong\u003e Factory-installed pressure relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCopper discharge and unloader tube:\u003c\/strong\u003e Durable and better heat dissipation than flex hose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotally enclosed metal belt guard:\u003c\/strong\u003e OSHA-compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFactory-Mounted Magnetic Motor Starter\u003c\/h2\u003e\n\u003cp\u003eThe -S suffix means the magnetic motor starter is factory-mounted and wired on this unit.
