Champion Duplex R-Series Piston Air Compressor

CHAMPION R-SERIES DUPLEX AIR COMPRESSORS (Duplex Variations)

Champion R-Series Duplex Reciprocating Air Compressors are built for operations that can’t afford downtime. A duplex package pairs two splash-lubricated, time-tested R-Series pumps on one receiver so you get higher output, built-in redundancy, and smoother demand coverage for real production air.

Built on the rugged R-Series platform

R-Series compressors are loaded with durability-minded details: multi-finned cylinders for cooler running, an integral cylinder/head design for trouble-free operation, serviceable disc valves, tapered roller bearings, and a balanced crankshaft designed to minimize vibration. Loadless starting uses a mechanical centrifugal unloader so the compressor starts unloaded every time—helping extend motor life.

High-output capacity that scales with your operation

At 175 PSI, R-Series simplex systems cover a wide performance range—and duplex packages are designed to roughly double the CFM output of comparable simplex units. That means you can supply more workstations and handle surges from multiple users without the system constantly falling behind.

Why choose a Duplex package

• Redundancy you can plan around: if one pump is offline for service, the other can still support operations
• Better duty management: alternating pumps can help balance wear over time
• One consolidated footprint: two pumps on a single ASME/NB certified receiver

Standard features that protect uptime

• Load-less starting (centrifugal unloader) for lower energy costs and less wear on the drive motor
• ASME inter-stage pressure relief valve for protection
• ODP NEMA 1760 RPM electric motors
• 10-micron industrial intake filtration
• ASME / NB certified receivers with 0–300 PSIG tank gauge
• Common single-phase and three-phase voltage availability

Options that make a duplex system “plant ready”

1. Air-cooled aftercooler – factory mounted and heavy duty; reduces up to 65% of moisture from discharged compressed air
2. Automatic electric tank drain – adjustable timed drain automatically discharges moisture from the receiver
3. Low oil-stop control – helps prevent operation when oil level is too low
4. Dual control and control upgrades – run start/stop or constant speed, add hour meters, and more
5. Motor/starter upgrades – TEFC motors, NEMA 4 upgrades, and other electrical options for harsher locations

Lubrication designed for reciprocating compressors

Champion ChampLub lubricants are blended specifically for harsh compressor environments and offered in mineral, synthetic, and food-grade options—helping you align lubricant choice with operating conditions and maintenance goals.

Warranty & support you can count on

R-Series packages include a standard warranty (including pump coverage) and can be extended with a Premium Warranty Kit. For duplex machines, two kits are required—one per pump—so both sides of the system are covered equally. Champion’s broad distributor network supports parts and service availability.

Pressure settings and configurations to fit the job

Duplex packages are available in multiple pressure ratings, and an 80 PSI setting is also available across R-Series packages for specialized low-pressure uses like climate control.

Typical duplex applications

• Manufacturing and fabrication floors
• Multi-bay automotive and fleet service
• Facility air for packaging, maintenance, and utilities

What you’ll notice on day one: faster recovery after big draws, more stable pressure for equipment that hates swings, and less stress around maintenance windows because you’re not “all or nothing” on one pump.
