Chicago Pneumatic CPS 400 KoD Towable Rotary Screw Air Compressor: 350 to 400 CFM, 100 to 200 PSI, 134 HP Kohler (400-150 and 400-200 MP)

The Chicago Pneumatic CPS 400 KoD towable rotary screw air compressor is the 150 to 200 PSI workhorse of the CP portable lineup, offered here in every factory configuration: the CPS 400-150 (400 CFM at 100 PSI, 375 CFM at 150 PSI) and the CPS 400-200 MP multi-pressure (350 to 400 CFM across a selectable 100 to 200 PSI), each as a standard, cold weather, or PFF aftercooled and filtered build. All run the 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 between the 250 KD8 and the 650 JD class. Pick your configuration from the menu above; the specs below describe the base 400-150.

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.

Choose your configuration

All five builds share the same Kohler KDI 3404TCR engine, C106 airend, 52 gallon tank and trailer. They differ in pressure range and factory packages. Select the one you need from the Configuration menu.

Trailer or skid

Every configuration ships on a DOT trailer (167 in long, 3 in pintle eye, 4 way flat lighting, VIN) unless you add the skid mount option below, which replaces the trailer with a 121 in skid base for flatbed transport, truck body mounting or permanent placement.

Factory options for the CPS 400

These are Chicago Pneumatic factory options. They are built onto the machine before it ships, so they are ordered with the compressor rather than as loose parts. Add the option part numbers you want in the order notes at checkout, or call (888) 229-9904 and we will add them to your order. Prices are add-on prices installed on the machine.

Hose reels are sold as their own items: single live hose reel for the CPS 400 (50 ft or 100 ft) and dual live hose reel for the CPS 400 (50 ft or 100 ft). Both require the extended drawbar.

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, with parts and service available through any Kohler power dealer in North America plus CP's authorized service network.

Frequently asked questions

What is the difference between the CPS 400-150 and the CPS 400-200 MP?

Same engine, airend and frame. The 400-150 runs a fixed 100 to 150 PSI range. The 400-200 MP adds a multi-pressure controller and 200 PSI rated separator so you can dial the working pressure anywhere from 100 to 200 PSI, trading a little volume (350 CFM at 200 PSI) for pressure.

What does PFF mean on the CPS 400-200 MP PFF?

PFF is Chicago Pneumatic's clean air package: aftercooler, water separator and coalescing plus particulate filtration built into the machine. Air comes off the outlet cool, dry and oil free enough for coatings, media blasting and instrument use without a separate trailer mounted dryer.

Does the CPS 400 need DEF?

Yes. The Kohler KDI 3404TCR is Tier 4 Final with SCR, so it carries a 4.5 gallon DEF tank alongside the 52 gallon diesel tank.

How is it shipped and what does freight cost?

The CPS 400 ships by flatbed or lowboy at 4,520 lb wet on the trailer. Freight is quoted per destination because a 167 in trailer does not go LTL; call (888) 229-9904 or email with your delivery zip and we will add freight to your order before it releases.

Can I order it on a skid instead of a trailer?

Yes. Add the skid mount option (0010001117) and the machine ships on a 121 in skid base instead of the DOT trailer.

Is financing available?

Yes. Equipment financing is available on the CPS 400; ask when you call or note it in your order and we will send the application.
