BendPak V-Max Patriot 7580V-601: 7.5 HP of two-stage air on ordinary single-phase service Shops that want a real two-stage cast-iron compressor usually hit the same wall. At 7.5 HP most of the market is three-phase only, and a building without three-phase service is then looking at a rotary phase converter, a utility upgrade, or settling for a smaller single-stage machine that will run flat out all day. The 7580V-601 is the version of this compressor built for 1-Phase, 208-230V, 60 Hz supply. Same 100% cast iron four-cylinder pump, same 80-Gallon vertical ASME tank, same 175 PSI ceiling as its three-phase sibling — connected to the kind of service an independent workshop, a serious home shop or a rural building actually has. What single-phase means at this size, honestly Single-phase does not make this a small machine, and it does not make the install trivial. BendPak's recommendation for this model is a 50 Amp breaker on a dedicated circuit. That is real electrical work: a panel with the capacity to spare, correctly sized conductors for the run, and an inspection in most jurisdictions. What it does mean is that the work is ordinary. An electrician can put in a 50 Amp single-phase circuit anywhere. Getting three-phase brought to a building that does not have it is a conversation with a utility, a lead time and a bill of an entirely different order — and that is the cost this model exists to avoid. A magnetic starter is specified as part of the machine, so the thermal overload protection a motor this size needs is not a separate purchase or an installer's improvisation. Will It Fit? Supply. 1-Phase, 208-230V, 60 Hz. Confirm the voltage at the panel, not on the nameplate of the machine next to it. Circuit. A 50 Amp breaker is the manufacturer's recommendation. Sizing the conductors for your run length is the electrician's job. Footprint. Vertical tank, so it trades floor area for height — see the dimensions note below, which is one of the figures this product's data does not state consistently. Weight. 936 lbs. (424 kg). The difficulty with a vertical compressor is not carrying it, it is standing it up in a doorway. Plan the route in before it arrives. Air and access. The pump is finned and air-cooled. It needs clearance around it to breathe and clearance above it to service the valves. The building, the ventilation, the electrical supply and any permits are yours to arrange. Ask us and we will confirm any published figure against the factory documentation before you commit; we will not tell you a room is suitable when we have not seen it. The pump is where the money went Motor speed is 1,750 RPM. Pump speed is 625 RPM. That reduction, through dual drive belts, is what lets a machine this size sit at 78 dB and is why the internals see so few cycles for the air produced. Two belts rather than one also means less tension on each, which takes load off the pump bearings and lengthens belt life. The cylinder arrangement is a "V-4" with finned cylinders giving 360° cooling. Cast iron matters here for a specific, unglamorous reason: heads and cylinders in iron keep their geometry under prolonged heat, while aluminium blocks with pressed-in sleeves are prone to distorting — and a distorted bore is a compressor that starts consuming oil. Disc-type valves are accessible without pulling the head or dismantling compressor piping, and the crankshaft is oversized ductile iron carried on tapered roller mains. Between the two stages sits an intercooler, and after the pump an air-cooled after-cooler. Both exist to take heat — and therefore water — out of the air before it reaches the tank. An electronic drain valve is also specified, so what does condense is removed on a schedule instead of whenever somebody remembers the petcock. Perfect For Independent workshops without three-phase service. This is the exact problem the model solves. Serious home and hobby shops. A two-stage cast-iron machine that a domestic-style panel can be built out to feed. Rural and outbuilding installations. Where a utility three-phase run is not on the table. Restoration, fabrication and tyre work. Continuous duty, 175 PSI, 80-Gallon reserve. What's in the Box Taken from the manufacturer's own feature list and specification, and nothing beyond it: 80-Gallon vertical ASME-rated tank, with ASME-rated safety valve 100% cast iron two-stage "V-4" pump, belt driven, with intercooler and after-cooler Magnetic starter, for thermal overload protection Electronic drain valve Four half-inch elastomer anti-vibration pads Dual drive belts inside a fully-enclosed guard Automatic pressure switch, with integrated unloader valves in the intake assembly Pressure gauge with service valve, and an oil sight glass on the reservoir 3/4" tank outlet No air dryer is fitted or supplied. If you spray finish coats, budget for one separately.

(424 kg) Three details to confirm before you order Published figures for this model differ on two points, and one wording difference is worth knowing about. Each is set out below with its source. Overall dimensions One listing on the spec sheet gives 34", with 610 mm, 1,829 mm and 864 mm as the three figures — although two of those three rows are both labelled "Depth", which is a transcription error on the sheet. A second listing on the same sheet reads 1,219 mm by 1,219 mm by 2,159 mm, larger on every axis, which would be consistent with a crated shipping size rather than the bare machine. Neither is labelled. If the footprint decides whether this fits your room, ask us in writing and we will confirm it with the factory before you order. Lubrication system The feature copy describes splash lubrication; the product's specification field records full pressure lubrication. Those are two different systems and they imply different servicing. Ask us to confirm it in writing if your maintenance plan depends on it. Country of origin BendPak's own text reads "Assembled in USA". The product title on this page reads "Made in USA". Assembly in the USA is not the same claim as manufacture of every component there. Both wordings are given here as published; if country of origin decides your purchase, ask us and we will confirm it with BendPak. Certification Certification to UL, CSA and ASME is stated in the manufacturer's specification for this model. Of those, ASME is usually the one that comes up in practice: it covers the tank and the safety valve, the components that contain and release the pressure. If an inspector or an insurer wants documentation rather than a sentence on a product page, ask us and we will send it. Pick up and delivery Pick-up for BendPak equipment is listed at Santa Paula, California and Theodore, Alabama. Availability moves between locations, so speak to us before making the trip — call, text or chat on 866-774-7743. Delivered orders travel by freight within the lower 48 states, free of charge. Arrange the unload in advance: a forklift, a loading dock, or collecting from the freight terminal yourself. Deliveries to a residential address carry an added fee, which appears at checkout before you pay. When it arrives, look the crate over first and record any damage on the bill of lading in front of the driver. Signing clean and finding damage later leaves you with very little to work with. Warranty This product's data links to BendPak's warranty document rather than stating a term, so no period is quoted here — read the linked document for the current terms. Independently of what it says: if something fails, leave it alone. Photograph it in place, keep the assembly intact and call us first. Warranty claims are lost to well-meant disassembly more often than to anything in the fine print.
