It comes in your choice of 230V or 460V, so you can match it to whatever 3-phase service you have on the floor. The vertical tank configuration keeps the footprint tight — a real advantage when every square foot of bay space is spoken for.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Detailed manufacturer specifications for this exact model are pending.

Here is how to decide:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e230V\u003c\/strong\u003e — Choose this if your facility's 3-phase service is 208-230V. Common in shops where the existing electrical service was designed around 230V equipment. Higher amperage draw for the same horsepower compared to 460V.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e460V\u003c\/strong\u003e — Choose this if your facility runs 460V (or 480V) 3-phase service. Lower amperage draw for the same HP — approximately half the amps of the 230V version. Runs cooler on longer wire runs from the panel. If you're running more than 50 feet of wire from the panel to the compressor, 460V is often the better choice from an efficiency and wire-sizing standpoint.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCheck your panel first\u003c\/strong\u003e — A 10HP compressor at 230V 3-phase draws roughly 28-32 amps. At 460V, roughly 14-16 amps. Your electrician needs to confirm breaker capacity and wire gauge before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eComparison: R1038VG11 vs. R10312VG11\u003c\/h3\u003e\n\u003cp\u003eThe R10312VG11 is listed at $9,027 — approximately $943 more than this unit at $8,084. Both are 10HP 3-phase vertical-tank rotary screw configurations. The price difference most likely reflects a larger tank size or a configuration update in the R10312VG11. If tank storage capacity is a priority for your operation — for example, if you run multiple air tools simultaneously during peak hours — it is worth asking about the tank volume on each model before deciding. The compressor head performance should be similar between the two; the tank simply affects how much reserve volume you have before the motor has to cycle.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Requirements\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3-phase electrical service required\u003c\/strong\u003e — This is not a single-phase unit.
