Champion HR15-12ADV 15 HP Two-Stage Horizontal Air Compressor Every compressor in a shop starts and stops dozens of times a day, and every one of those starts is where the wear happens. The HR15-12ADV is built around a centrifugal unloader that vents the pump whenever the machine is at rest, so the motor spins up against nothing and only takes the load once it is already turning. That one design choice touches the breaker size, the belt life, the motor life and the lights in the rest of the building. Around it sits a heavy duty two stage, splash lubricated R-40 pump rated 15 HP, delivering 54 CFM at a maximum working pressure of 175 PSI, on a horizontal receiver. The pump carries a 3 year warranty. Loadless starting, and why it is not a footnote Start a compressor with pressure still sitting on the pistons and the motor has to overcome that pressure from a standstill. The inrush current is high, the belts slip and glaze, and in a building with marginal supply you watch the lights dim. Do it forty times a day for a decade and you have paid for the difference several times over in electricity, belts and eventually a motor. The centrifugal unloader removes that fight entirely. The pump is vented at rest, the motor comes up to speed unloaded, and the unloader closes once it is there. Champion's own note on the feature is about lower energy costs and less wear on the drive motor, and it is one of the few claims on a compressor spec sheet that a shop can verify for itself simply by listening to it start. A pump designed to shed heat rather than store it Two stage compression is the headline: air is squeezed part of the way, run through large diameter finned intercoolers where it dumps heat, then finished in a smaller cylinder. Cooler air at 175 PSI means less moisture carried into the receiver and less thermal stress on the rings and valves. The detail underneath supports it. Multi-finned cylinders and an integral cylinder head design pull heat out of the casting instead of trapping it. Domed pistons with high efficiency lap joint rings and a bi-directional seal hold compression without a heavy, dragging ring pack. Tapered roller main bearings and a balanced crankshaft keep the assembly steady under load, and automotive style two-piece connecting rods make a rebuild a rebuild rather than a replacement. An optimized cooling fan and flywheel move air across the whole of it. A 10 micron industrial grade intake filter keeps abrasive dust out of the bores in the first place, which is wear prevention at its least expensive. Because this is an Advantage build, the accessories arrive fitted rather than quoted separately: a mounted NEMA 1 control panel with a control voltage transformer and thermal overload protection, vibration isolator pads, an automatic tank drain and a low oil level monitor that will not let the machine restart until the oil is corrected. Will it fit, and what does it need? Start with the supply, because it is the item that most often stops an installation on the day. This is a three phase machine built for 208 V, 230 V or 460 V, and Champion asks you to specify the voltage when ordering. There is no single phase build, so a building with single phase service only needs a different compressor, not a different order. Have an electrician confirm the supply and breaker before you buy. The machine is roughly 73 inches long and weighs about 1,210 lbs. It needs a solid, level floor; the isolator pads take out vibration and forgive a slab that is slightly out of true, but they do nothing for a soft or cracked one. Leave clear air around the cooling fan and intercoolers rather than pushing it into a corner, or the machine ends up drawing in its own hot air. The receiver has a 3/4 inch service outlet for the shop main. Overall width, overall height and the tank volume are recorded in our data without a usable unit, so we have not printed them here rather than guess. Ask us and we will read them from the factory drawing before you commit. Perfect for Busy two to four bay shops running impacts, lifts and blow guns through a full working day. Tyre and alignment operations with constant short-cycle demand, where start frequency is the wear driver. Fabrication shops feeding plasma, grinders and sanders that pull steadily rather than in bursts. Buildings with three phase service and a supply the owner would rather not stress on every start. What is included Two stage, splash lubricated pump, factory filled with ChampLub lubricant Horizontal code stamped air receiver with relief valve, service valve, drain valve and gauge Mounted NEMA 1 control panel with control voltage transformer and thermal overload protection Vibration isolator pads Automatic tank drain, pneumatic or adjustable electric time drain Low oil level monitor with restart lockout Oversized 10 micron intake filter and silencer, enclosed belt guard Oil level sight glass and 0-300 PSIG tank gauge Specifications Model HR15-12ADV Motor 15 HP Air delivery 54 CFM Maximum pressure 175 PSI Pump R-40, two stage, splash lubricated, simplex Supply Three phase, 208 V, 230 V or 460 V (specify when ordering) Tank orientation Horizontal Tank outlet 3/4 inch Overall length 73 inches Weight 1,210 lbs Magnetic starter Included Integrated air dryer Not fitted Warranty 3 year, compressor pump One number the source data gives twice Champion's literature for this series prints two different motor speeds: 1800 RPM motors in the R-Series feature list, and a 1760 RPM ODP NEMA electric motor in the standard features list on the same sheet. They are not the same figure and we are not going to quietly choose the one that reads better. If motor speed matters to you, for a starter selection, a spares order or a noise calculation, ask us to confirm it against the build sheet for the unit you are buying. Certification, stated honestly The receiver is described as a code stamped air receiver with a pressure relief valve, and the pump has an inter-stage relief valve. Beyond that our product record holds no third-party safety listing for this compressor, and we are not going to imply one that our data cannot support. That is a statement about our records rather than a judgement on the machine. If an insurer, a local inspector or a plant safety audit needs a particular listing or stamp, name it and we will confirm it against the factory documentation before you order. Shipping and delivery Freight truck only, within the contiguous United States. Around 1,210 lbs on a pallet puts this well past any parcel service, and it ships free of charge. You are responsible for unloading, so arrange a forklift rated comfortably above the shipping weight or choose terminal pickup and collect it. A residential delivery address carries a residential fee, shown in the checkout quote before you pay. Inspect the pallet before you sign for it: crushed corners, torn wrap, a bent tank foot, a damaged gauge or oil on the deck all go on the bill of lading in writing, backed by photographs. Signing clean says the machine arrived undamaged. Warranty and support Each new assembled unit carries a 3 year warranty on the compressor pump. Full terms and the claim route are on our warranty claims page. Do not strip the pump or the control panel to diagnose a fault before the claim is opened, because a disassembled component is the most common reason a valid claim is refused. Call it in, let us document it, then take instruction. For voltage, crated dimensions or the figures withheld above, call, text or chat with us on 866-774-7743.
