Atlas Copco X-Air 185-100 Cold-Weather Towable Rotary Screw Air Compressor

Atlas Copco X-Air 185-100 Cold-Weather Towable Rotary Screw Air Compressor

The Atlas Copco X-Air 185-100 Cold-Weather Towable Air Compressor is a 189 CFM, 100 PSI rotary screw diesel unit built specifically for contractors, rental fleets, municipalities, and utility crews that have to keep working when temperatures drop. Powered by a turbocharged Kubota D1803-T 49 hp Tier 4 Final diesel engine with DOC aftertreatment and no DEF requirement, this towable compressor delivers dependable performance, long service intervals, and easy towing in a compact footprint.

This cold-weather configuration adds extended-life synthetic compressor oil, heating elements, and a thermostatically controlled oil system so the machine starts reliably and reaches operating temperature quickly, even in sub-freezing environments. The result is less downtime, reduced wear, and fewer service interruptions throughout the winter season.

Key performance specs

• 189 CFM free air delivery at 100 PSI working pressure, 125 PSI maximum
• Fuel consumption 2.37 gal/hr (8.97 L/hr)
• Kubota D1803-T Turbo 49 hp Tier 4 Final diesel engine, DOC only (no DEF)
• Two 3/4" air outlets with claw type (Chicago) couplings, standard
• Minimum pressure valve and load valve for easy starting and smooth loading
• PAROIL M Xtreme compressor oil as standard on base units (1,000 hours / 2 years service interval)
• Cold-weather configuration upgraded to PAROIL S synthetic compressor oil (1,500 hours / 2 years service interval)
• Spin-on separator filter for fast, clean service
• 110% fluid containment for all engine and compressor liquids
• External lifting eye for safe hoisting on and off trucks, platforms, or jobsite decks

Air outlets and connections

The X-Air 185-100 ships standard with two 3/4" air outlets fitted with claw type (Chicago) couplings. That means two crews can run tools off one machine straight out of the box with the industry-standard coupling already installed, no adapters and no plumbing changes. Loose ball couplings in alternate sizes are available as a factory option if your fleet standardizes on something else.

Built for cold-weather productivity

The "Cold-Weather" package is what separates this towable X-Air 185-100 from standard portable units that struggle in winter. Instead of fighting cold starts and thick oil, the compressor is engineered to handle low temperatures as part of its core design.

Cold-weather features include:

• PAROIL S synthetic compressor oil with extended 1,500 hour / 2 year service interval
• Engine block heater to pre-warm coolant and aid cold starts
• CCV heater (crankcase ventilation heater) to prevent freezing of vapors and moisture in the breather system
• Thermostatic bypass valve on the compressor oil system so oil reaches optimum temperature quickly while still protecting internal components

These upgrades mean more reliable starts, faster warm-up, less internal condensation, and lower long-term maintenance costs for operators who work through freezing conditions.

Smart XC1004 controller for easier operation

The X-Air 185-100 Cold-Weather Towable model uses the Atlas Copco XC1004 controller for clear, simple machine management. This controller is designed specifically for mobile compressors, with real-world jobsite use in mind.

Key controller benefits:

• Operational monitoring of engine and compressor status
• Diagnostics and fault history for easier troubleshooting
• Safety warnings and automatic shutdowns for conditions such as high engine temperature, high compressor outlet temperature, low fuel, and critical engine faults

The interface is easy to understand and quick to train on, helping keep operators focused on the work, not the machine.

Towable package: standard scope of supply

This description applies only to the towable version, not the deck-mounted variant. The X-Air 185-100 Cold-Weather Towable is built around a road-ready heavy duty single axle trailer that is designed to live behind a truck every day. The following are standard equipment, not options:

• Heavy duty single axle trailer
• Heavy duty torsion axle rated at 2,500 lbs
• US DOT / Federal MVSS 49CFR571 approved light package and 4-way trailer plug
• Adjustable height pintle hitch with 3" lunette
• Safety chains
• Screw jack leveling
• 13" rims with ST205/75D13 trailer tires
• Single point lifting structure
• VIN tag
• No brakes (simple, low-maintenance tow-behind design)

If you are bidding public or federal work, note that this standard package already satisfies the running-gear language that shows up in most solicitations: DOT-approved lighting, a 4-way plug, an adjustable-height pintle with a 3-inch lunette, safety chains, and an adjustable jack. No adders required.

Factory options

• Extended drawbar with hose reel, available in 50 ft or 100 ft, single or dual reel configurations
• Loose ball couplings in alternate sizes
• OSHA valve
• Toolbox
• 15" wheels with 205/75R15 tires
• Support mount frame, no wheels, for deck mounting

The single point lifting structure allows the entire towable unit to be lifted as a single piece with a crane or forklift hook attachment when needed, making it easy to relocate on tight job sites or stack yards.

Faster service and lower operating cost

Every minute a portable compressor is down for maintenance is lost production. The X-Air 185-100 Cold-Weather Towable is laid out for quick, clean service so technicians can get in and out fast.

Service-friendly features:

• Spin-on separator filter for rapid change-out
• Logical component layout with easy access to filters and fluids
• Extended compressor oil intervals (up to 1,500 hours / 2 years with PAROIL S on the cold-weather configuration)
• 110% fluid containment frame to help prevent environmental incidents and cleanup costs

Over the life of the machine, these design choices reduce downtime, cut labor hours for maintenance, and help deliver a lower total cost of ownership for fleet managers and contractors alike.

Dimensions and weight

• 130" long x 62" wide x 69" high
• Approximately 2,100 lbs wet weight

Top 5 reasons to choose the X-Air 185-100 Cold-Weather Towable

1. True winter-ready design
   Engine block heater, CCV heater, synthetic compressor oil, and thermostatic bypass valve work together as a system so the compressor starts, warms up, and runs reliably in cold climates.
2. Strong air output in a compact towable unit
   189 CFM at 100 PSI is ideal for powering multiple pneumatic tools, sandblasting, and general construction air demands from a single, easy-to-tow package, and it clears the 185 CFM threshold that most bid specs are written around.
3. No DEF, less hassle
   The Kubota D1803-T Turbo Tier 4 Final diesel engine uses DOC-only aftertreatment, so there is no DEF fluid to store, handle, or worry about on remote or seasonal jobsites.
4. Complete DOT running gear standard
   A 2,500 lb torsion-axle DOT trailer with lights, 4-way plug, 3" pintle, safety chains, and screw jack leveling, plus 110% fluid containment and a single point lifting structure, all included rather than optioned.
5. Lower maintenance burden and downtime
   Extended oil intervals, spin-on filters, logical service access, and integrated safety monitoring all work together to reduce surprise failures and keep the compressor earning money instead of sitting in the shop.

If you need a towable cold-weather air compressor that can live on the road, start in the cold, and stay productive with minimal maintenance, the Atlas Copco X-Air 185-100 Cold-Weather Towable Air Compressor is a purpose-built solution designed to keep your crews working when lesser machines shut down.
