At just a foot high and less than two feet wide out of the carton, this compressor was quite a bit smaller than we expected, so to be fair, we quickly lowered our expectations. The joke was on us, though, because this little powerhouse just doesnt quit, and we learned that you cant judge a compressor by its size. We should have known better when the first thing we saw was the word “Emglo” emblazoned in black on that famous DeWalt yellow. Emglos half-century in the compressor business is evident in this model, and with a couple of small exceptions (well get into that in a minute), we dont think anyone could make a finer piece of air power. Structurally, its top-notch. DeWalt/Emglos great new roll-cage shape protects your investment in the shop, in the truck and at the job site, and the gauges are easier to read than many weve squinted at over the years. It weighs in at around 60 pounds, and the way the handles designed, you can carry it much like a suitcase without overexertion. To let out any moisture thats accumulated, its just an easy turn of the ball-valve tank drain, then just wrap the cord on its holder and youre ready to go. In the performance department, we have to say this machine blew us away, moving 4.5 cfm at 100 psi. Now, this may be a plus or a minus in your book, but we liked the fact that the compressor is factory set to power on at 100 psi an+d shut off at 120 psi, and the cycle time was under 15 seconds. We didnt find it unusually loud, but were given to wearing hearing protection with tools such as this one anyway (and we hope you are, too.) It has air aplenty for two nailers at once, and with that fast recovery, the job will get done in no time. If we had to say what we didnt like, there are two items on that list: First, we thought the power switch would have been better seated on the front panel rather than the side, but thats a miniscule complaint. What you do want to watch out for, though, is the proximity of the reset switch to parts that get searingly hot while in use. A little care will save you some pain. In balance, this is one of the best compressors weve seen for the size, power, ruggedness and incredible portability it offers. Heres to a great pairing of two great toolmakers.–Kris Jensen-Van Heste
DeWalt’s 2-horsepower, 4-gallon compressor features an oil-lubricated design with a cast-iron cylinder to guarantee job site durability. The D55155 is overload protected, as well, and delivers 4-1/2 cfm at 100 psi while still drawing less than 15 amps. The new roll-cage design and integrated control panel protects the compressor and the controls from accidental damage. The panel houses two large easy-to-read gauges, the regulator, and two universal quick couples. Carrying the compressor is easy, too: the flat design lets the user tote the compressor comfortably like a suitcase. Other features include a ball-type tank drain and a wrap area to store the power cord. The 4-gallon tank is ASME approved and CSA certified. The package comes with the initial fill of DeWalt synthetic air compressor oil.
