Rated 5.0 out of 5.0 by Contractor Tested We have run this little girl everyday for several hours at a time.It sits out In the weather on back of the work truck.I have pushed,pulled and dragged this machine through all kinds of terrain.Very satisfied and will buy the Identical if we ever ruin this one November 19, 2013
Rated 1.0 out of 5.0 by Not a long term tool I'm a small contractor, used to buy a lot of Dewalt tools. After buying the first compressor it last for almost a year, then the belt broke. I replaced it, a month later it broke again. I loved the wheels and portability so bought a new one, after two months the bolts on the compressor head blew off. To repair would involved taking the head off, drilling out the broken bolts and replacing. On both models there was a constant problem where in cold weather one of the relief valves would stick and it would hiss all day. I used it for trim and framing guns, it wasn't unusual for me to be running two guns. After two compressors in fourteen months, I purchased a competitor's product. Strongly recommend staying away from this one. September 5, 2014
Rated 5.0 out of 5.0 by Workhorse I have owned this compressor for 5+ years and I love it. The telescoping handle and large pneumatic wheels make it very easy to move around the job. It holds plenty of air and recovers quickly. I do lots of high end finish and framing work and this compressor has no problem running multiple guns all day long. In five years all I have had to do is change the air filter and replace one of the pressure gauges. March 2, 2013
Rated 5.0 out of 5.0 by Has What Is Needed At 200 PSI Tank Pressure And 150 PSI Coming Out, Plus Being So Portable. This Is The One To Choose, Not So Heavy You Need Two People To Load Or Unload, For Me It Is Easy In Or Out Of My Vehicles , Extendable Handle Is Just Like Toting Suitcase Around, Plus Dewalt Brand Seems To Always Be A Winner !!!!!!!!

Rated 5.0 out of 5.0 by buying second one after 5 years of daily use. I’m buying a replacement tonight for my old one that finally dead today. It was a real good machine (not perfect but real good). Year 3 it needed a pressure gauge $20 and ten min. Year 4 it needed a tire $25 and 30 min. Year 5 the pressure regulator went out so I used a inline one that I had around the shop. About two months later the head broke on the compressor pump. I have used this compressor a lot and it has held up better then some of my more expensive ones I’ve had in past. April 19, 2010
Rated 5.0 out of 5.0 by Awesome Air Compressor I am a Do It yourselfer who can do anything to a vehicle except rebuild an engine or transmission. The compressor handled a Campbell Hausfield impact wrench rated at 4.7 CFM, Model # TL140299AV, with no problem. It also had no problem operating a 3/8 inch harbor freight professional (haha) air ratchet (great ratchet though, have had it for over a year). The compressor operates at 200 psi which is definitely a plus. It only took about 1 minutes or less to fill the tank. It is a little noisy but not as much as my porter cable pancake compressor. In fact the noise is not that annoying, sounds strong. Only time will tell on how dependable this unit is but so far it is great. January 1, 2015
Rated 5.0 out of 5.0 by Works great with air chisel I needed a compressor that could handle an air chisel for removing tile, and for drilling through the sub-floor of my house to install a new drain. Air chisels are very demanding of compressors. When I borrowed a neighbor's compressor and chisel, it would run out of pressure every couple of minutes, and I would have to wait for the pressure to build back up. This unit handled an air chisel with no problem. After 15-20 minutes of continuous use, I was still going strong. Sure, the motor ran non-stop, but I was able to keep going. Very nice built-in dolly. I'm happy with my purchase! July 16, 2011
Rated 5.0 out of 5.0 by Good compressor...for the price I'm a contractor. I've been looking at compressors for a while. I almost bought the bigger 15 gal compressor. But now, I'm glad I didn't. This thing really pumps up fast! It isn't on long and you are ready to go. It keeps up with a framing nail gun all day without a hitch. I really like the wheels and portability. Weight is easy to manage for me. Perfect for what I need. I also have a pancake compressor by porter-cable. It has been a good compressor, but it strains more to keep up with my framing nail gun. For a job-site contractor, this is no sweat for this Dewalt compressor. June 12, 2014
