Best Doosan Air Compressors
1. Doosan C185 –
The Doosan Air Compressor C185 is a small, but powerful machine. It’s a high-pressure model that has been designed for many applications such as fiber optic cable installation, pipeline testing, sandblasting, and more. Let’s take a look at some of its features.
A Powerful Machine
The C185 is a powerful machine that features a 74 horsepower Tier 4-F-compliant engine. At full load, the machine can run for 12.6 hours at a time. The 3-cylinder engine has a Bhp of 46 @ 36.6 kW, ensuring you always have the best performance.
The machine does run on fuel and has a tank capacity of 34.5 gallons.Additionally, the C185 delivers 185 cfm @100 PSI.
Since these machines have to be portable, they have to be durable. The C185 has a refined galvanneal-steel canopy design that protects it from job site abuse. It can be easily lifted for quick maintenance or access to all of its service points. Easy access to these locations is crucial to keeping your job going efficiently and smoothly.
Easy to Use
The C185 features a curbside discharge valve and cleanout ports that are much safer than the model before it. You will be able to access all of the filters easily and they are marked.
There’s also a separated oil tank that is equipped with an upgraded fill and sight gauge. Let’s not forget about the LED-backlit control display. This allows you to read the gauges wherever and whenever you need to.
2.Doosan XP375WCU-TU – 375 CFM Air compressor
If you’re looking for something just a little more powerful than the C185, then check out the XP375WCU. This model features a strong Cummins engine, many new features, and a completely redesigned user interface.
Here are some other notable features that come with the Doosan XP375WCU.
This machine has a much stronger engine than the C185. It’s equipped with a Cummins B3.9 engine with 4 cylinders. It ensures all of your power tools and other accessories are well-powered. It has a CFM of 375 @ 125 PSI with an air discharge outlet size of 1.25 inches. It holds a whopping 63 gallons of fuel and can run longer.

3.Doosan VHP400WCU-T4F – Doosan Air Compressor HP 450
The Doosan VHP400WCU-T4F is another rugged compressor that has proven its reliability, performance, and serviceability.
Much like the XP375WCU, it has the Cummins engine that has been proven to provide these compressors with the power they need to help you perform your duties. Here are some other highlights:
Powerful Compact Engine
This compressor is powered by a Cummins QSB 4.5L Tier 4 Final compliant engine. It features DOC and SCR emissions technology in a smaller size than the others. It has a two to one diesel exhaust fluid vs diesel fuel fill ratio.
This ratio is important to companies that rent out these compressors because they are frequently used by customers who may not be used to filling them with two fluids in the newer engines.
As far as air delivery goes, this compressor puts out 12.7/11.3 CFM @ 450/400 PSI. This is more powerful than the other compressors we have seen thus far. Additionally, at full load, low-pressure operation time is 8.5 hours and high pressure is 8.3 hours.
Along with a new motor comes new technology. One of the newly redesigned components of the compressor is its Miniport full gauge control panel. There is a handy tachometer display that lets you see the engine and its air end temperatures.
You can use the panel to set service intervals, set languages, and different display features. You can also change the pressure and flow setting while the compressor is running with the Mini Port.
4.Doosan P425 –
Last on our list is the Doosan Air Compressor P425. This is yet another powerful machine there for you when you need it. Powered by its rugged Cummins engine, it allows you to increase productivity and lowers the cost of owning the machine. Here are some of the more notable features of it:
The Doosan p425 has a sturdy design featuring a galvanneal steel enclosure that’s resistant to corrosion. It also has an A-frame drawbar and heavy-duty axles that help tote the compressor around.
When moving from job site to job site, it’s important that your machine can handle a ding here and there. Most importantly, the shell protects the inner mechanics of the compressor.
Industrial air compressors aren’t known for being overly quiet, but the p425 is different. It’s constructed with a thermostatic clutch-driven cooling fan that allows the compressor to run quietly and smoothly. Not only that, but it cuts down on fuel costs by roughly 10% in cold weather.
Lastly, the Doosan p425 has a powerful Cummins QSB 4.5 L engine in it that puts out 12.0/10.6 CFM @ 425/375 PSI. Not quite as much as the VHP400WCU-T4F model, but it’s still great for power tool versatility.
It has a 60-gallon fuel tank capacity and can run for 10.9 hours at low pressure and 10.6 hours on high pressure.
Doosan is a name known across the globe. They are well-known for their heavy machinery and portable air compressors. They boast of having the hardest working and most reliable equipment on the planet.

Typical Doosan Air Compressor Error Codes
With new technology comes error codes. We see them on everyday items such as video game consoles, cell phones, websites, and more. There are some common error codes that come with your Doosan air compressor which are the fault code 29 and the air compressor not starting. Let’s go over why this happens.
Doosan Air Compressor Fault Code 29
When the Doosan air compressor throws this code, it has now shut the engine down without any user input and there was no Engine Diagnostic Code detected. Why did this happen? This is a fault condition and it shuts down the compressor. Here’s how to fix it:
Step 1: Check The Fuel System for Restrictions
If there are dirty fuel filters that have yet to be changed since the last service, change them. If you used dirty fuel, add clean fuel, and replace the filters. If air is present in the fuel system, bleed it out. Lastly, if the fuel hoses are damaged, replace them.
Step 2: Check Battery Terminals, Starter, and Alternator
If there are loose connections on the harness or they are damaged, repair as needed.
Step 3: Turn Key switch to any ON Position to Energize the Compressors Electronic System & Use a Multimeter to Measure Key switch Signal Voltage at P1-2
The voltage meter should read 12 VDC at P1-2. If it doesn’t, check that all of the connections on the harness to the key switch signal circuit are intact.
Step 4: If Steps 1-4 Are OK, Refer to The Engine Manufacturer Service Dealer
Doosan Air Compressor Won’t Start
There are quite a few things that could make your Doosan portable air compressor not start. Here are some of the most common reasons:
Completely Dead: Check the battery. Check if the battery isolation switch is on. Make sure a safety switch hasn’t been tripped.
Doesn’t Crank: If the compressor doesn’t crank, ensure a safety switch has not been tripped. Check electrical connections and make sure the safety switch isn’t pressed.
Cranks But Won’t Start (Diesel): A diesel engine needs compression and fuel to start. Check the fuel system. If there is fuel in the tank, replace the filter.
Pump, prime, pump. Vent low-pressure and high-pressure fuel system to remove air, check out stop solenoid, and speed setting. Sometimes the stop solenoid can have a dirty valve or it breaks down. This cuts off the fuel and stops the engine from working.
