Champion CA-Series S Oil-Free Rotary Scroll Medical Air System | Duplex, Triplex and Quadraplex, 5-10 HP

Champion CA-Series S Oil-Free Rotary Scroll Medical Air Systems

The Champion CA-Series S medical air system is a 100% oil-less rotary scroll plant built specifically for hospital and clinical medical air. Air never touches lubricant anywhere in the compression path, so there is no oil carryover to manage, no oil analysis programme and no oil-removal filtration train to maintain downstream. Champion builds these packages to NFPA 99 and CSA requirements, with every multiplex system rated on full system output with one compressor held in reserve, which is how NFPA 99 expects a medical air source to be sized.

Three airend sizes are offered, CA-S5 at 5 HP, CA-S7 at 7.5 HP and CA-S10 at 10 HP, each available as a duplex, triplex or quadraplex system. Duplex systems come on a base with a remote 80 gallon receiver, or tank-mounted on an 80, 120 or 240 gallon horizontal vinyl (epoxy) lined receiver. Triplex and quadraplex systems stack three or four airends and motors on a common base and ship with a remote 80 gallon receiver as standard.

Every system on this page is quoted from the Champion August 15 2026 price list. Compare-at is the published list price, and the Warthog price is what we sell it for. Lead times, freight and site-specific accessories are confirmed when we write the order.

What the Configurations Mean

• Duplex, base mount with remote 80 gallon receiver. Two airends and two motors on one base, with the receiver set remotely. This is the layout to pick when the mechanical room has floor space for a separate tank or when the tank has to live in another room.
• Duplex, 80 / 120 / 240 gallon horizontal tank. Two airends and two motors mounted directly on a horizontal ASME receiver. Vinyl (epoxy) lining is standard on all three tank sizes. Piping and wiring are included on tank-mounted medical systems, so the package arrives as one assembled plant.
• Triplex, base mount with remote 80 gallon receiver. Three airends and three motors stacked on a common base. Ships with the MediTrol Plus HMI control panel as standard.
• Quadraplex, base mount with remote 80 gallon receiver. Four airends and four motors on a common base, again with MediTrol Plus HMI standard. This is the largest configuration in the range.

Voltage is an order-entry choice, not a price axis. The CA-S5 and CA-S7 list identically for 208/230V single phase and 208/230/460/575V three phase. The CA-S10 is three phase only; no single phase row is published for it.

Champion does not publish a sound level for the open-frame CA-Series S, medical or industrial. We will not quote a dBA figure we cannot source from the factory. If sound matters in your space, ask us and we will request the measured data from Champion before you commit.

Factory-Installed Options and Adders

Priced options are sold on a companion listing so you can add exactly what the job needs: Champion CA-Series S Medical Air System Factory-Installed Options and Adders. That listing carries galvanized and vinyl lined receiver coatings, larger 120 and 240 gallon remote receivers, the MediTrol Plus HMI upgrade for duplex systems, mounted and stand alone medical desiccant dryer systems with dew point and CO monitoring, and Massachusetts code fittings.

Included at no charge, so they are not sold as separate line items:

• Vinyl (epoxy) lined receiver on every tank-mounted duplex system
• Remote 80 gallon vinyl lined receiver on every base-mount duplex, triplex and quadraplex system
• MediTrol relay control panel on duplex systems
• MediTrol Plus HMI control panel on triplex and quadraplex systems
• Bypass isolation valves on all tanks, and the electronic tank drain
• Piping and wiring on tank-mounted medical systems

Also Available by Quote

The following are printed in the price book without a list price, so we quote them per order rather than sell them from the page:

• Massachusetts receiver risers: 306SIS4013 (30 gallon horizontal), 307SIS4013 (80 and 120 gallon horizontal), 308SIS4013 (240 gallon horizontal). The Massachusetts code fittings themselves are priced and are on the options listing.
• CA-S10 mounted medical desiccant dryer at 140 PSIG, and the CA-S10 stand alone medical desiccant dryer at 140 PSIG. Both print as Call on all CA-S10 configurations.
• Stand alone medical desiccant dryer on the CA-S5 duplex base mount. The book prints N/A there, while the CA-S7 and CA-S10 duplex base mount systems are priced. Ask us and we will confirm with the factory.

Ideal Applications

• Hospital and surgical centre medical air plants built to NFPA 99
• Dental and outpatient clinics needing certified oil-free breathing-quality air
• Laboratory and research air where hydrocarbon contamination cannot be tolerated
• Veterinary surgical suites and imaging facilities
• Any retrofit replacing an oil-lubricated medical plant where the oil-removal train has become the maintenance burden

Service, Parts and Accessories

Scroll airends are consumable by design: the tip seals and bearings are replaced on a schedule rather than run to failure, and the interval is shorter at 140 PSIG than at 116 PSIG. Champion sells the CA-Series scroll airends as service replacement assemblies, and we stock and quote them alongside intake filters and aftercooler parts. Champion Service Department is reachable on 815-875-3321.

Tip seal service interval is 10,000 hours at 116 PSIG and 5,000 hours at 140 PSIG. Replacement bare air ends are stocked in both industrial and medical order-entry versions, and a medical system takes the medical part number: see our Champion CA-Series Oil-Less Rotary Scroll Bare Air End listing.
