Champion HR10-12: a two-stage 120-gallon compressor that lies down instead of standing up Almost every 120-gallon shop compressor you will be shown stands upright, because a vertical receiver is the most economical way to buy air storage per square foot of floor. The HR10-12 solves the opposite problem. Its receiver lies horizontally, and the whole package measures 71" long by 55" tall, which is low enough to sit under a mezzanine, a duct run, a garage door track or a ceiling that an upright tank of the same volume would foul. What sits on top of that tank is a heavy-duty two-stage, splash-lubricated reciprocating pump turned by a 10 HP motor, rated to 175 PSI and supplied for 230V service. It is a continuous-shop machine rather than an intermittent one, and at 895 lbs it is meant to be set once and left there. Will It Fit? A compressor this size fails on the building far more often than it fails on performance. Measure before you order, not after the freight arrives. Overhead clearance. The unit stands 55" tall. Add whatever you need above it to lift the belt guard, change oil and reach the safety valve without dismantling anything. Run length. It is 71" long, so it wants a wall run rather than a corner. Leave air on all sides: a reciprocating pump is air-cooled and a compressor boxed tightly into a nook runs hotter than one with room around it. The third dimension. Our data does carry an overall width, but the figure is stored without a unit written beside it, so we are not going to print a number we cannot stand behind. Ask us and we will read the width off the factory drawing before you commit to a wall. Electrical service. Supplied for 230V. Have an electrician confirm your available supply and the breaker sizing for a 10 HP motor before delivery day, because retro-fitting a circuit after the machine is on the floor is the expensive order of operations. Floor and handling. 895 lbs is a forklift or pallet-jack job, and it wants a flat, solid slab. Air connection. The tank outlet is 3/4". Size the shop main to the tools rather than to the outlet. Your responsibility. Site preparation, supply, permits, offloading and placement are the buyer's to arrange. We can tell you what the machine needs; we cannot inspect your building for you. Two stages, and the intercooler that sits between them The phrase "two stage" gets printed on spec sheets without explanation, so here is what it buys. A single-stage pump takes atmospheric air and squeezes it to final pressure in one movement, and all the heat of that compression stays in the air and in the cylinder. A two-stage pump squeezes it partway in a large cylinder, pushes it through an intercooler, and only then squeezes it the rest of the way in a smaller one. Cooled air is denser, so the second stage has less volume to move for the same delivered pressure. The practical result is a pump that can hold 175 PSI without cooking itself, which matters more in a hot building than a cool one. Multi-finned cylinders and an integral cylinder head back that up: the metal that gets hottest also carries the most surface area to shed heat. The details that decide how long it lasts Splash lubrication and an oil-level sight glass make the one maintenance check that matters a walk-past rather than a job. Oversized main bearings and a balanced crankshaft address what actually retires reciprocating compressors — vibration working fasteners loose over years — and high-flow disc valves are the wear item that governs efficiency as the machine ages. The centrifugal unloader is worth understanding as an electrical feature rather than a mechanical one. It vents the head so the motor starts against no pressure. A 10 HP motor asked to start against a loaded head draws its worst inrush every single cycle; on a shared shop panel that is the difference between starting cleanly and browning out the lights or nuisance-tripping a breaker. What the option list tells you about this pump The published options for this model include an electric fuel pump, a canvas cover for engine-driven models, heavy-duty vibration isolators, and standalone fuel tanks in 9-gallon and 5-gallon sizes. Fuel pumps, fuel tanks and a weather cover only make sense on an engine-driven machine, which tells you this pump family is also sold on a skid for sites with no power. On the electric unit here the option that will actually matter to most buyers is the vibration isolator set, particularly if the compressor shares a wall with an office or a paint booth. Perfect For Shops with a height problem. Low ceilings, mezzanine undersides, basement workshops and buildings where the roll-up door track eats the useful headroom. Multi-bay automotive service. Impact tools, lifts, tyre machines and blow guns running together on a 120-gallon reserve. Body and paint work that needs steady pressure rather than a tank that empties into a gun mid-panel. Light industrial and fabrication where the compressor is expected to work a full shift, not a weekend. What's in the Box A packaged unit: the two-stage splash-lubricated pump with its intercooler, multi-finned cylinders and integral head, the 10 HP motor, the 120-gallon horizontal receiver, an enclosed drive, an oil-level sight glass, a centrifugal unloader and a magnetic starter. No air dryer and no electronic drain valve — raise either before you order rather than after. The fuel pump, canvas cover, vibration isolators and the 9-gallon and 5-gallon fuel tanks are options, not inclusions.

Published figures for the free air this unit delivers differ, and one is recorded with no unit attached to it at all, so no delivery figure is printed on this page. If your decision turns on air delivery — and on a machine of this size it usually does — ask us and we will confirm it against the factory data sheet in writing before you buy. Electrical phase. One catalogue entry records this unit as three-phase; the manufacturer's specification list leaves the phase field blank. Because phase is the one thing you cannot change your mind about after the crate is opened, treat it as unconfirmed here and have us verify it against your building's supply before the order is placed. Certification, stated plainly The data we hold makes no third-party safety-listing claim, and we are not going to invent one. Pressure vessels and shop electrics are subject to local rules that vary by jurisdiction, and some insurers and fleet operations require a specific listing on the packaged unit. If that applies to you, ask us to confirm what documentation ships with this machine before you order. Shipping and delivery Freight to the lower 48 states, free of charge. You need to be able to take an 895 lbs crate off a truck — forklift, loading dock, or a pallet jack and a level approach — or collect it from the carrier's terminal instead. Residential addresses carry a residential fee. Walk the crate before you sign: check the tank for dents, look for shipping damage around the pump and motor, and note anything you find on the paperwork. A signed clean receipt makes a damage claim very hard to win afterwards. Warranty Our record links to the store's warranty claims page without stating a term, so we are not printing cover we cannot evidence — ask us for the current manufacturer terms in writing before ordering. One rule always applies: if something goes wrong, call us before you disassemble anything. Opening a pump before the claim is raised is the commonest way a valid claim becomes an invalid one.
