Atlas Copco XAS 185-150 PACE Towable Rotary Screw Air Compressor

The Atlas Copco XAS 185-150 PACE Towable Rotary Screw Air Compressor is a compact, diesel-powered machine that delivers true 185 CFM performance with adjustable pressure control from 100–150 PSI. Designed for contractors, rental fleets, and industrial users, this tow-behind unit combines fuel efficiency, durability, and easy service access in a robust package that’s ready for daily jobsite abuse.

High-performance 185 CFM, 100–150 PSI output

At the heart of the XAS 185-150 PACE is an oil-injected rotary screw air end driven by a Kubota Tier 4 Final diesel engine. Together, they provide dependable compressed air for a wide range of tools and applications, from breakers and rock drills to sandblasting and utility work.

Key performance highlights:

• Free air delivery up to 185 CFM (at selected pressures)
• Adjustable working pressure range: 100–150 PSI
• Single-stage, oil-injected rotary screw design
• Optimized for continuous duty in tough environments

This flexibility means one towable compressor can cover multiple jobs instead of needing separate units for different operating pressures.

Kubota Tier 4 Final diesel power

The XAS 185-150 PACE is powered by a Kubota V1505-CR-T-E5B Tier 4 Final 44 HP mechanical diesel engine, built for long life and reliable performance in harsh conditions.

Engine features:

• 44 HP, liquid-cooled, 4-cylinder turbo diesel
• Mechanical design with starter protection and cold-start capability
• Tier 4 Final emissions compliance
• Fuel system with an anti-airlock design to help guarantee starting
• Electrical shutoff switch for safety

This engine delivers the torque and stability required to maintain airflow and pressure under varying load, while meeting modern emissions requirements and keeping operating costs controlled.

Smart control with PACE and XC2003

One of the defining features of the XAS 185-150 PACE is Atlas Copco’s PACE (Pressure Adjusted through Cognitive Electronics) system, controlled through the XC2003 digital controller.

Benefits of PACE and XC2003:

1. Adjustable pressure control

• Set operating pressures between 100 and 150 PSI.
• Fine-tune output for different tools and applications.

2. Automatic flow optimization

• As pressure changes, the controller manages flow to maximize available CFM at the selected pressure.
• Helps avoid overworking the engine or wasting fuel.

3. Intelligent monitoring and protection

• Digital interface for pressure, hours, alarms, and diagnostics.
• Warnings and shutdowns for events like low oil pressure, high temperatures, or engine faults.

4. Fuel-efficient operation

• The system helps match air production to actual demand, supporting lower fuel burn across a typical workday.
• For contractors and rental users, PACE effectively turns one tow-behind compressor into a multi-pressure machine that can be quickly adapted to new jobs without hardware changes.

Rugged towable design for real jobsites

This is a true towable version, not a deck-mounted unit. It’s engineered as a complete mobile package that can be hooked up and moved between jobs with minimal hassle.

Tow and chassis highlights:

• DOT-approved towing package
• Road lights with 4-way flat electrical plug
• 3" pintle towing hitch for standard work trucks
• Torsion axle for stable towing and improved ride
• VIN-tagged frame for registration and fleet management
• Adjustable jack stand/support leg
• No brakes on the standard configuration

The compact footprint and relatively low tow weight make it easy to maneuver into tight spaces, city streets, and crowded jobsites while still delivering serious air power.

Built to last: canopy, frame, and containment

Atlas Copco’s 8-series towable compressors are built around a durable, weatherproof enclosure and corrosion-resistant frame designed to take abuse and keep running.

Construction and durability features:

• Polyethylene canopy built for heavy-duty applications
• Base frame with 3-layer anti-corrosion paint for long life
• 110% spill-free containment with remote drains to capture and control fluids
• Thermostatic bypass valve on the compressor oil system for stable operating temperatures
• Pressure vessel with spin-on filter for easier maintenance

The spill containment frame and drain points help keep jobsites environmentally compliant and reduce cleanup time if a line or component leaks.

Fast, straightforward maintenance

Downtime costs money, so the XAS 185-150 PACE is laid out for fast service with minimal tools.

Service-friendly design includes:

• Wide-opening polyethylene canopy for full access
• Filters and fluids grouped for easy reach
• Spin-on compressor oil and fuel filters
• Clearly laid-out service points largely accessible from one side

Typical service tasks such as filter changes, oil checks, and cooler inspections can be completed quickly, making it ideal for rental fleets and contractors who need maximum uptime.

Typical maintenance workflow

1. Open the canopy to access filters, drains, and fill points.
2. Replace the spin-on compressor oil filter, fuel filter, and engine oil filter as needed.
3. Check compressor oil, engine oil, and coolant levels.
4. Inspect coolers and air filters; clean or replace if required.
5. Drain any collected fluids from the 110% containment frame via the remote drains.

This straightforward approach keeps service time down and the compressor back in the field earning.

Ideal applications and use cases

Thanks to its variable pressure range and 185 CFM performance, the Atlas Copco XAS 185-150 PACE Towable Rotary Screw Air Compressor is suited for a wide variety of jobs.

Perfect for:

• Road and bridge work using breakers, hammers, and saws
• Sandblasting and surface preparation
• Concrete repair and shotcrete support
• Utility, pipeline, and cable installation work
• General construction and industrial maintenance
• Rental fleets needing one unit to cover many pressure requirements

If you need a rugged, towable diesel compressor that can adapt to different tools and pressures, stays efficient, and is easy to service, the XAS 185-150 PACE towable version is built for exactly that.
