Output is 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. The vertical tank stands 75 inches tall on a 44 x 30 inch footprint. Weight is 860 lbs. Three-phase power means cooler motor operation and lower starting current versus the single-phase equivalent. The vertical configuration keeps the floor footprint compact.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eStarter configuration:\u003c\/strong\u003e Confirm at time of order — call 866-217-0063.

Here is what separates these from lighter-duty machines:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll cast iron construction\u003c\/strong\u003e — cylinder heads, crankcase, and cylinders are cast iron throughout. Cast iron manages heat better than aluminum and wears far more slowly under continuous load.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered roller bearings at both ends of the crankshaft\u003c\/strong\u003e — not ball bearings. Tapered rollers handle both radial and thrust loads simultaneously, which is exactly what a reciprocating pump crankshaft sees in operation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision steel connecting rods with automotive-type insert bearings\u003c\/strong\u003e — at both the crankshaft journal and the wrist pin. These are the same bearing design used in automotive engines. They are replaceable when worn — not a throwaway assembly.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc and spring valves\u003c\/strong\u003e — simpler to service than reed valves, more efficient at high discharge pressures, and more reliable over years of cycling.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-ring pistons\u003c\/strong\u003e — two extra rings versus typical 2-ring piston designs. Better compression sealing, significantly less oil carry-over into the air stream.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentrifugal unloader\u003c\/strong\u003e — the pump starts unloaded on every cycle without exception. This reduces motor starting current, reduces wear on the motor and belts, and eliminates the hard-start problem common in compressors that attempt to restart against pressure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTank, Motor, and Controls\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME-coded steel tank\u003c\/strong\u003e — powder-coated for corrosion resistance.

This means the motor can sustain loads above its nameplate rating without tripping.
