If your shop runs on single-phase power and you need a compressor that runs continuously without cycling on and off, this unit delivers 100% duty cycle operation at a compact footprint — 34 inches wide, 26 inches deep, and 70 inches tall. It is built in Minnesota by Castair, a manufacturer that focuses exclusively on cast iron, oil-lubricated compressors built for long service life in automotive, industrial, and agricultural shops.\u003c\/p\u003e\n\n\u003cp\u003eThe G11 air end designation means this unit uses the Castair G11 rotary screw element — a larger, slower-turning air end compared to the P75 entry-level element, designed for shops that want lower operating temperatures and longer service intervals. The vertical 80-gallon ASME tank keeps the footprint tight while providing enough storage volume to handle intermittent high-draw tools without the compressor straining to catch up.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Exact CFM output for the G11 air end at 10 HP is not published on the Castair spec table (the P75-based R1018VP75 delivers 40 CFM at 100 PSI).
