It weighs 480 pounds and measures 34 inches wide by 26 inches deep by 70 inches tall. The vertical tank configuration takes up significantly less floor space than the horizontal version — 34\"×26\" versus 64\"×32\" — making this the better choice when you need to preserve floor space and ceiling height isn't a constraint. Single-phase 230V power means no 3-phase service required, which makes this unit accessible to shops that have standard commercial power.\u003c\/p\u003e\n\n\u003ch3\u003eVertical Tank — Floor Space Efficiency\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall footprint:\u003c\/strong\u003e 34\"×26\" base takes up less than 6 square feet of floor space.
