Champion VRV10-12: 34 CFM standing on a 42.68-inch base

Most shops do not run out of air. They run out of room, and then buy the compressor that fits rather than the one that suits the work. The VRV10-12 is aimed squarely at that: 34 CFM at 175 PSI from a 10 HP motor, with a 120-gallon receiver stood on end so the whole machine occupies a base of 42.68".

You give up nothing else to get it. Same RV30 pump, same 1,800 RPM motor, same 895 lbs, same working pressure and the same packaged simplex build as the horizontal model. The only thing that changes is which dimension of your building the compressor spends.

What an ASME coded receiver is actually telling you

The feature list for this model says the receiver is ASME coded, and adds an exclusion in brackets that is worth reading rather than skipping: base-mount versions of the package are not covered by that statement. Coding a pressure vessel is a design, materials and inspection discipline applied to the tank itself, and on a shop compressor it is the difference between a vessel built to a recognised standard and one built to a drawing. It is also the thing an inspector or an insurer is most likely to ask about first.

The same list states that the receiver is compliant with California code. Whether that is a requirement or an irrelevance depends entirely on where you are installing, but it is a genuine claim about the tank rather than a marketing line, and it travels with the machine.

Loadless starting, and why it is really an electrical feature

Every time a compressor cuts in, its motor has to break away. If the head is still pressurised, it has to do so against that pressure, and it draws its worst inrush current doing it. Loadless starting vents the head so the motor accelerates unloaded and only then takes up work.

On a 10 HP motor in a shop sharing a panel with lifts, lighting and welding equipment, that is not a refinement. It is the difference between a compressor that cycles unnoticed and one that dips the lights and eventually earns itself a bigger breaker and an electrician's invoice. The tank-mounted simplex start/stop pressure switch is the other half of the arrangement — a deliberately simple control with nothing to programme and one thing to adjust.

Will It Fit?

• Ceiling, before anything else. Our data holds an overall height for this unit as a bare number with no unit recorded next to it, so no clearance figure appears on this page. On a vertical 120-gallon receiver that is the number that decides whether the machine fits at all — ask us and we will confirm it from the factory drawing before you order.
• Base. 42.68" square. That is the whole argument for this variant, and it still wants clear air around it, because the pump is air-cooled.
• Slab. 895 lbs on a compact footprint, tall and top-heavy once uncrated. Flat, level and sound — not a timber deck, not a patched corner.
• Supply. Listed for 208 / 230 / 460 / 575V three-phase, fixed at order time. Agree it with us and your electrician before it ships.
• Air connection. 3/4" tank outlet, high on the vessel, which usually shortens the first run of pipe.
• Your responsibility. Slab, supply, permits, offload and placement are the buyer's to arrange.

Perfect For

• Shops trading height for floor — a compressor in a corner instead of along a wall.
• Two and three-bay service work with impact tools, lifts and intermittent grinding.
• Light manufacturing benches that need a steady 175 PSI rather than headline output.
• Buyers who want it pre-wired, with the starter and controls fitted at the factory.

What's in the Box

A packaged simplex unit: the RV30 pump, a 10 HP motor at 1,800 RPM, the vertical 120-gallon ASME coded receiver, a mounted NEMA 1 magnetic starter as standard, tank-mounted start/stop pressure switch control, an intake filter and silencer, an enclosed belt guard and loadless starting. No air dryer and no electronic drain valve are fitted — on an upright tank in particular, that makes the manual drain a habit somebody has to own.

Specifications

A note about the air delivery figure

The table gives our catalogue's rating of 34 CFM, and that is the only delivery figure we will put in front of you. The manufacturer's specification list instead carries two values, taken at 125 PSIG and at 175 PSIG, each recorded without a unit beside it, and both a shade under the catalogue number. The factory document is the more cautious of our two sources — but a number whose unit our own data never states is not a number we will republish as air delivery. Ask us for the data sheet in writing if your air budget is tight.

Certification, stated plainly

Everything this page claims about certification comes from the product's own feature list and is repeated above: an ASME coded receiver, base-mount versions excluded, and compliance with California code. No third-party safety listing is claimed for the packaged machine anywhere in the data we hold, and we will not invent one to fill a heading. Where an insurer, a fleet policy or a local inspector requires a specific listing, ask us to confirm in writing what accompanies this unit before you order.

Shipping and delivery

Freight to the lower 48 states, free of charge. 895 lbs crated needs a forklift, a dock, or a pallet jack and a level approach; if none of those exist at your end, collect from the carrier's terminal instead. A residential fee applies to residential deliveries. Check the shipment before you sign for it — along the receiver for dents, around the pump, motor and starter enclosure for impact — and note anything at all on the delivery paperwork there and then. Damage recorded at delivery is a claim; damage found the next morning usually is not.

Warranty

The record we hold links to the store's warranty claims page without naming a term, so this page names none — ask us for the current manufacturer terms in writing before you order. Then protect them: report a fault before anything is taken apart. A compressor already opened up is the hardest kind of claim to get paid.
