The Chicago Pneumatic CPS 185-100 KoD towable rotary screw air compressor is the long-shift specialist of the 185 CFM class: 180 CFM at 100 PSI from a 49 HP Kohler KDI 1903 TCR Tier 4 Final diesel, paired with a 27-gallon fuel tank that delivers 11.4 hours of continuous full-load runtime. For crews running extended shifts, remote-site work where refueling is inconvenient, or rental customers who want one tank to cover a full workday plus reserve, the 185-100 KoD is the answer.
The 11-hour shift compressor
Most 185 CFM portable diesels carry 15-25 gallons of fuel and run 6-8 hours under continuous full load. The CPS 185-100 KoD carries 27 gallons and burns 2.37 gal/hr at 100% — that's 11.4 hours of full-load autonomy, the longest in the 185 CFM class. At typical 50-75% jobsite duty cycles, you're looking at 14-18 hours of operating time per tank. Practical impact:
- Top off in the morning, work all day, top off the next morning — no midday refueling
- Run overnight (e.g., cable jetting, fiber install in conduit) without operator attention
- Stage on remote jobsites where fuel delivery is logistically difficult
- Rental customer satisfaction goes up — they don't burn through fuel during their rental window

Where the 185-100 KoD beats the field
Construction crews on multi-week jobs
The longer fuel autonomy translates directly into lower operating cost per day — fewer hours spent refueling and more billable hours running tools. On a typical 3-week project, an 185-100 KoD will deliver 30-40 additional hours of productive air supply versus a competitor 185 with a smaller tank.
Rental fleets
The single biggest complaint from compressor rental customers is running out of fuel mid-shift. The 185-100 KoD's 11.4-hour autonomy eliminates almost all single-shift refuel events, dropping rental fleet support calls and improving customer satisfaction scores.
Remote utility and pipeline work
Where mobilizing a fuel truck to the jobsite costs $500+ per visit, every refuel skipped is money saved. The 185-100 KoD's extended autonomy pays for itself quickly on linear infrastructure projects.
Cable jetting and fiber installation
Long fiber pulls can run overnight in commercial and utility conduit. The 185-100 KoD's tank capacity supports unattended overnight operation.
Common applications
- General construction, breaker and chipping work
- Multi-tool jobsites (two ¾-inch tools simultaneous)
- Light to medium sandblasting
- Pneumatic valve actuation and pipeline support
- Cable jetting / fiber installation
- Fence and post installation
- Concrete repair and demolition
- Water well service and development
- Rental fleet (most demanded 185 size with long runtime)
Standard configuration
- Kohler KDI 1903 TCR Tier 4 Final diesel (49 HP)
- Single-stage oil-injected rotary screw airend
- CP XC1004 controller with disconnect and diagnostic display
- 110% fluid containment frame
- 27-gallon diesel fuel tank
- 2 × ¾" NPT service air outlets

- Skid mount — for permanent installation, truck-body mounting, or marine deck use
- Galvanized canopy hardware — extended corrosion resistance for coastal and marine environments
CPS 185-100 KoD vs. CPS 185 KDU — which 185 do I need?
| Feature | CPS 185-100 KoD | CPS 185 KDU |
|---|---|---|
| Engine | Kohler KDI 1903 (49 HP) | Kubota V2403 (49 HP) |
| Fuel tank | 27 gal | 25 gal |
| Full-load runtime | 11.4 hr | 8+ hr |
| Sweet spot | Long-shift / remote work | Utility crews, line trucks |
Both are excellent 185 CFM machines. Choose the 185-100 KoD if extended fuel autonomy is your top priority; choose the 185 KDU if you need the direct-driven C111 airend and Kubota engine service network.
