Champion R-Series Engine-Driven Piston Air Compressor

Champion R-Series engine driven air compressors, gas and diesel

Twenty-two factory configurations, from a 13 HP Honda on a bare skid to a 23.9 HP Yanmar diesel on an 80 gallon tank. These are the compressors you buy when there is no power at the work: service trucks, trailers, pipeline and utility crews, road and bridge work, remote sites, and shops that need air where the panel does not reach.

Every one is a Champion R-Series splash lubricated two-stage pump, the same pump family as the electric R-Series, driven by an industrial engine instead of a motor. All engines come with electric key start. All pumps come with head unloaders so the machine runs constant load/no load rather than cycling the engine.

Gas or diesel is the first decision

Gas is cheaper to buy and lighter. The 13 HP Honda GX390 base unit lists at $8,200 against $16,810 for the 9.1 HP Kohler diesel, and the diesel gives you less air at 20.1 CFM against 23.2. On paper the gas wins easily.

Diesel wins on the things that are not on paper: fuel availability on a site that already runs diesel equipment, run hours between rebuilds, torque under a sustained load, and fuel handling rules on sites that will not allow gasoline. If the machine will run most of the day, most days, the diesel is the cheaper machine in year three. If it runs an hour at a time a few times a week, buy the gas one.

Model selection chart

Capacity is quoted at 175 PSIG, which is the rating that matters on these. The 4x2 gallon option is a low profile twin tank layout for truck mounting where height is the constraint.

The Kohler is a horsepower bigger and costs less across the board. The Honda has the longer reputation and the easier parts supply in most of the country. The air they make is identical, because it is the same R15 pump at the same speed.

Standard on every engine driven package

• Electric key start switch on all engines
• Champion R-Series splash lubricated two-stage pump
• Head unloaders for constant load/no load operation
• ASME coded receiver on tank models, excluding base mount and the low profile twin tank
• Intake filter and silencer
• Enclosed belt guard
• Vibration isolators
• Pilot valve with toggle on tank mounted units, for loadless starting without bleeding the receiver down
• 9 gallon EPA certified fuel tank on the 22 HP gas and 23.9 HP diesel
• Exhaust rain cap on the 23.9 HP diesel

Electric start engines ship without a battery. Champion does not supply one. Buy it locally and size it to the engine.

Base mount or tank

Base mount gives you the pump, engine and skid with no receiver, for mounting into a truck body or trailer that already has air storage, or where you are plumbing into a remote tank. It is the lightest and cheapest way in. The tradeoff is that without a receiver the machine has nothing to buffer demand, so it only makes sense if storage exists elsewhere.

The 4 gallon twin tank on the HGR7-LP models is the truck mount answer: enough storage to run impact tools without the height of a 30 or 60 gallon horizontal. Note it is not an ASME coded receiver, unlike the 30, 60 and 80 gallon tanks.

Options

Remote start and choke kits, vinyl lined and galvanized tanks, air cooled aftercoolers, lifting eyes, exhaust rain caps and the premium extended warranty kit are all on the companion listing: Champion R-Series engine driven factory-installed options and adders. They are factory line items, so they go on the order with the machine. Two ship loose accessories, the TEN003329 remote choke and start kit and the P12845A canvas cover for 30 gallon models, are printed without list prices and are available by quote.

One thing to check early: remote start and choke is not available at all on the 13 HP Honda GX390 machines. If you need to start the compressor from the cab, that rules out five of the twenty-two.

Where these earn their keep

Service and mechanic trucks. Utility and line crews. Pipeline work. Fencing, drilling and anchor crews. Bridge and highway maintenance. Rental fleets. Any sandblasting or impact work away from a building. If you have power at the wall, buy an electric machine instead: it is quieter, cheaper and lasts longer, and our electric piston range covers the same pumps.

Freight

Champion prepays freight on engine driven compressors when the order is over 400 pounds, which covers every tank model and most base mounts once options are on. Weights above are Champion's published estimates per configuration from the August 2026 book. Call us for current factory lead time, which moves around on the diesels more than the gas units.

Buying from Warthog

We are an authorized Champion Pneumatic distributor and these are priced from the current August 15, 2026 list. Tell us the tool or the job, the duty cycle and whether the site runs gas or diesel, and we will tell you which of the twenty-two fits. We will also tell you when a base mount plus a tank you already own beats buying a packaged unit.
