Champion Base-Mounted R-Series Piston Air Compressor

Champion R-Series base mount: pump, motor and starter with no tank

A base mount package is a complete R-Series compressor without the receiver: two stage splash lubricated pump, ODP 1760 RPM motor, belt drive and guard, intake filter and a mounted magnetic starter, all on a steel base. You buy one when you already own a good ASME tank, when the receiver has to sit somewhere else because of floor space or noise, when you are replacing a worn out base mount unit on an existing system, or when a 240 or 400 gallon receiver is the right size and no tank mounted package comes that large. It is also the normal way to add a second compressor to a plant that already has a receiver and dryer.

The range runs from the 2 HP BR2 at 4.1 CFM to the 30 HP BR30 at 101.8 CFM, all rated 175 PSI. In the middle: BR3F 8 CFM, BR5 17 CFM, BR7F 22.3 CFM and BR7 25.6 CFM at 7.5 HP (the F models use the smaller R15 pump turning faster, the non F models the larger R30 pump), BR10 33.8 CFM, BR15F 48.7 CFM and BR15 54.1 CFM, BR20 77.8 CFM, BR25 90.7 CFM. Single phase 208 or 230 volt is available through 7.5 HP; 10 HP and up are three phase 208, 230 or 460 volt. Each unit ships wired for the one voltage you select in the dropdown.

What you need to add: a receiver sized at roughly 3 to 4 gallons per CFM (a 120 gallon tank for a BR10, 240 gallons for a BR25 or BR30), a pressure switch or a dual control pilot valve, a safety valve and tank gauge, a discharge line with a check valve, and an automatic drain. Base mount units are not California code receivers because there is no receiver; the tank you buy carries that. Our Morganton and Samuel ASME tanks cover 30 to 1060 gallons, and pressure switches, drains and starters are stocked.

Pair the compressor with a refrigerated dryer rated at or above its CFM and a filter set. If you would rather have the tank included, the same pumps come as the vertical simplex, the horizontal simplex and the duplex.

Manufacturer description

CHAMPION R-SERIES BASE MOUNT SIMPLEX AIR COMPRESSORS

Champion R-Series Base Mount Simplex Reciprocating Air Compressors deliver dependable, two-stage compressed air.

R-Series engineering you can feel

• Multi-finned cylinders to help run cooler
• Integral cylinder/head design aimed at reducing head-gasket failures
• Disc-type valves designed for long service and easy servicing by removing manifolds
• Tapered roller main bearings + balanced crankshaft for smooth operation
• Loadless starting so the compressor starts unloaded every time

Standard features (no fluff)

• Load-less starting via centrifugal unloader
• ASME inter-stage pressure relief valve
• ODP NEMA 1760 RPM electric motor
• 10-micron industrial grade intake filtration
• ASME / NB certified receiver + 0 to 300 PSIG tank pressure gauge
• Common single-phase and three-phase voltage options

Upgrade paths that improve air quality and uptime

1. Air-cooled aftercooler: reduces up to 65% of moisture from discharged compressed air
2. Refrigerated drying: cools air to roughly a 33 to 39° dew point to reduce downstream condensation
3. Automatic electric tank drain: timed draining to discharge receiver moisture automatically
4. Low oil-stop control: protects the unit if oil level drops
5. Dual control: run start/stop or constant speed mode
6. Electrical & motor upgrades: NEMA 4 starter and TEFC motor options for harsher environments

Pressure options for real applications

R-Series packages are commonly configured for higher-pressure shop air, and an 80 PSI setting is also available across the line for dedicated low-pressure uses like climate control.

Lubrication, warranty, and support

Champion ChampLub lubricants (mineral, synthetic, food-grade) are made specifically for compressor environments. R-Series packages are backed by a strong warranty program, with optional premium coverage, and supported by a broad distributor network.

Common applications

• Automotive and fleet maintenance shops
