Chicago Pneumatic CPS 400-150 Towable Rotary Screw Air Compressor – 400 CFM @ 150 PSI

The Chicago Pneumatic CPS 400-150 KoD towable rotary screw air compressor is the 150 PSI workhorse of the CP portable lineup — 400 CFM at 100 PSI or 375 CFM at 150 PSI, delivered by a 134 HP Kohler KDI 3404TCR Tier 4 Final diesel. For pipeline crews, large sandblasting operations, multi-tool construction sites, and drilling support work, this is the medium-duty machine that sits in the sweet spot between the 250 KD8 and the 650 JD class.

Why 400 CFM @ 150 PSI is the right answer for so many jobs

150 PSI changes what's possible on a jobsite. Standard 100 PSI machines starve high-pressure pneumatic tools like 1-inch impact wrenches, pipeline torque tools, and large abrasive blast nozzles. The CPS 400-150 delivers 375 CFM at full 150 PSI — enough headroom to run high-pressure tools and support standard 100 PSI tools simultaneously from one machine. That's a category of capability you can't get from a fixed-100-PSI 400 CFM unit.

At-a-glance specs

Pipeline construction: the natural home for the CPS 400-150

Pipeline contractors are the largest single market segment for 400 CFM @ 150 PSI portable air. The combination of high pressure, high volume, and a footprint that still fits standard ROW access roads makes the CPS 400-150 the default spec for:

• Pneumatic torque wrench banks on flange make-up
• Hydrostatic test pump support
• Pneumatic valve actuation and operation
• Pipeline pigging propulsion
• Pneumatic spray on internal/external coatings (with aftercooler option)
• Sandblasting weld prep and coating removal

Large sandblasting and surface prep

375 CFM at 150 PSI runs 2-3 large blast nozzles continuously. For bridge maintenance, ship and barge work, tank exterior blasting, and water tower repaint projects, the 400-150 is right-sized to keep multiple blasters productive without oversizing the diesel package. Spec the optional aftercooler and water separator if your spec requires dry air at the blast pot.

Drilling support and air-hammer work

For shallow water well, geothermal, and exploration drilling, the 400-150 supports air-rotary drilling on smaller rigs and percussion hammer work. The 150 PSI capability is critical for DTH applications where higher starting pressure dramatically improves penetration rate.

Trailer or skid: choose your configuration

Chicago Pneumatic offers the CPS 400-150 in both trailer-mounted (167" L, full DOT towing package) and skid-mounted (121" L, designed for transport on flatbed or installation on a truck body) configurations. Trailer is the right choice for rental fleets, multi-site contractors, and crews that move the compressor frequently. Skid is right for permanent installation, marine deck use, or transport on company flatbed equipment.

Standard configuration

• Kohler KDI 3404TCR Tier 4 Final diesel (134 HP, DEF required)
• CP C106 single-stage oil-injected rotary screw airend
• CP XC2003 controller with diagnostic display and operating-hour log
• RedRock™ polyethylene canopy with three-layer painted metal
• 110% spill-free containment frame
• 1 × 1½" NPT + 2 × ¾" Chicago claw service air outlets
• 52-gallon diesel + 4.5-gallon DEF tanks
• Synthetic compressor oil, 1,000-hour service interval
• Heavy-duty 2-stage air filtration
• Cold-start capability to -13°F with optional starting aid
• Internal toolbox
• Lifting eye and forklift pockets
• DOT towing package (trailer config): 3" pintle eye, road-legal axle, 4-way flat plug lighting, VIN

Factory options worth considering

• Aftercooler + water separator — required for paint prep, instrument-quality applications, and any coating work
• Electric brakes — for heavier wet weight transport on trailer config
• Extended fuel tank connection — for jobs running longer than 8.8-hour shifts
• Heated enclosure package — for sub-zero permanent installations

Service intervals and operating cost

Synthetic compressor oil rated for 1,000 hours. Engine oil and DEF per Kohler KDI 3404 manual. Air and fuel filters oversized for jobsite dust loads. The Kohler KDI 3404 is one of the most widely supported Tier 4 Final diesel engines in the world — parts and service available through any Kohler power dealer in North America plus CP's authorized service network.
