MOTION PICTURE IA - The only thing I can say is EMGLO! I have been using Emglo compressors for over 15 years years now in the Motion Picture Industry and on the outside and I never would settle for less. I was a little skeptical at first when I saw Dewalt and Emglo had merged to make a new line. I must say I prejudged and thought well there goes the dependability and quality of Emglo's Compressors. However I had a chance to use one and you know what, it was an Emglo all the way and I purchased this little powerhouse that I can even use a conventional spray gun on it.
Emglo (Dewalt) compressor - I have had this compressor for about 6 months or so. I got this compressor when i had to put baseboards and crown moldings in a house. I looked at both the Hitachi and Dewalt compressor for about 4 months before i got it. I like the design of the old Emglos a lot better with the twin stacked tanks but I can live with this design. The reason why I bought this one over the Hitachi is it has a little more CFMs at 100psi and i have known the reputation the Emglos carry with them from seeing them on the job regularly. This compressor also has a roll cage to protect the motor that is nice and can come off easily to access the motor. Overall this Emglo I mean Dewalt works really well and I'm pleased with it.
A pleasure to own! -

The biggest complaint I have about other compressors is the portability of them. This helps to center the weight to my body and I can then lug the compressor up several flights of stairs without passing out.

The main reason I bought this unit over cheaper compressors was the recommendation to the brand names of DeWalt and Emglo. I now see why others recommend the Dewalt and Emglo brand.
A very good compressor - I replaced my hotdog style oil-less compressor when the connecting rod decided to break.

While at the local hardware store I saw the DeWalt D55155 compressor and thought, "geez, you could not miss that compressor!" The bright yellow paint made this compressor stand out and then that's when I saw the name Emglo. I have had very good experience with Emglo and know their equipment is top notch.

DeWalt and Emglo have a winner. This compressor also has a ball valve on the bottom of the tank for easy draining. This ball valave is also inside the frame as is every component of the compressor. It's mounted inside the roll cage near the copper line running from the compressor to the tank. It might be, but, I put the compressor away from where I'm working so this is not an issue.

As with any compressor you have to keep the extension cords short.

So, would I buy this compressor again if I had to? You bet!.
Good compressor - I have owned this compressor for 6 months now. This compressor has performed flawlessly. I change oil every 2 or 3 months with Emglo synthetic oil to maximize the life of my purchase. Recommend to anyone looking for reliable portable air that will last.
roofer wayne - I used many compressors in 28 years of roofing. This is my 3rd emglow and 2nd dewalt. My first emglo lasted 12 years. The only thing that was wrong with the first dewalt was the air regulator started leaking and had to be replaced. Other then that, it worked every day for two years so far,that with two or three roofing guns going which is like four framing guns and I did not notice it starving for air.This compressor is the best and durable for the Professional.
Great !!! - After reading the reviews on Emglo compressors, I decided to get this DeWalt compressor because of the compact design. I highly recommend this compressor but I could not give 5 stars, not knowing how well it will hold up (although it is not a concern).
DeWalt takes a classic to a new level - Last yearI spent many months researching a replacement for my ailing Campbell-Hausfeld oilless compressor. Originally I figured the CH had a higher air output, needed no oil changes,would work on slopes and start in cold weather.After forking over the big bucks and putting it to work for DeWalt's 30 Day trial period I couldn't believe I'd gone so long without this compressor.
1) First of all the Emglo name on the unit reassured me that I was getting a tool built by the industry leader with a great reputation for tough, dependable compressors. The first day on the job proved it with quick cycling times and ample air at all times. I do a lot of work in luxury high rises and I've often left the compressor at home rather than drag it down endless corridors. I've paid for the compressor already in labor savings by bringing it to every trim job. I've had othe craftsmen come over and ogle the compressor and ask questions about it, but mostly admiring it.

In short, this is a serious tool for the professional contractor with loads of power(delivered air), durability, great design and looks. DeWalt took a classic, the Emglo 790, and improved the power output layout and design. My only complaint is the air release lever, an otherwise solid unit mounted on the underside of the tank. The opening is too narrow for your hand and the sharp stream of air can actually cut your skin. In addition the compressor shoots out small chunks of ICE from the tank creating dangerous projectiles that will cut your hand or riccochet into your eye.
Finally, I have a compressor that won't roll around in the back of the truck knocking off gauges and connections as I drive through the city. Hats off to DeWalt and Emglo for a match that combines legendary durability with great design.
Good Purchase - I also heard from Emglo which makes the unit for DeWalt. This is my first compressor purchase.00 for the compressor purchase? I qualify for the rebate but not so keen on their guns, hence no $$$ back.
Dewalt and Emglo make a complete package, great compressor! - Someone decided they needed my trim compressor more then I did so I had to purchase another one. I must admit I was not to broken harted about it though because I have had my eye on Dewalt's new compressor now for some time. The sleek design, the way it protects its gauges, and its 2 quick conect air ports kept calling me every time I saw this compressor. I was not disapointed!! The unit is a little heavy for a portable compressor at over 60 lbs. Inside a house a compressor's noise can seem to be greatly magnified but this unit seems almost quiet, it runs so smooth. I had a larger compressor for framing but this Dewalt compressor has done so well that I have sold my larger one and rely on just this one. The unit really has no real flaws at all the air drain has a great little lever to drain the tank with, but it does blow out hard if you open it to quick and I am not convinced it drains all the condesation real well. There is a little black breaker on the compressor unit which can be a little dificult to locate and reset, it would be nice if on a newer version Dewalt would move it to the front with the gauges and quick connects. It has triped several time on us if we try and run too many things at a time such as a miter saw, table saw, and the compressor, but for normal use the draw of this compressor seems fine even on a 15amp breaker.
To sum it all up this is one really nice complete package compressor!! It is small enough for the little jobs yet tough enough for the more demanding jobs, within reason, remember it is only a 4 gallon, running at less the 15amp, compressor. With Dewalt and Emglo combine you will not go wrong buying this compressor, and unless you get a defective unit which happens with all products from time to time, you will have a compressor that should last a long time.
A nice small compressor - I bought this air compressor to do light construction work. I have to say that I was a little skeptical at first about using a small compressor for roofing or framing nailers but I was satisfied after the first time I used it. This compressor has impressed me more than most of my other tools. I have ran the compressor off of 100 foot 12 gauge cord and haven't noticed any problems at all. I have a gas powered Emglo compressor and the quality is outstanding. Other than that it has been a really great compressor and I would recommend this compressor over any other in its class. It may cost a little more but you won't have to replace it like the other compressors.
Great Performance - Dewalt/Emglo designed this compressor around portability.there is very little room in the opening to not only grasp and turn the valve, but if the valve is opened too quickly, be prepared for full discharge of air. Another design area that could use improvement is the location of the two pegs/studs for stowage of electrical cord in order to move compressor. With cord wrapped around the two pegs, natural movement of compressor is to roll it onto it's side in order to pickup and carry with one hand. When cord is stowed it extends outside the compressor's frame therefore, when compressor is rotated onto it's side the wrapped cord comes into contact with the ground resulting in compressor bearing it's weight on cord. Outside of two design improvements, air compressor is a great performer.
Good machine, but some packaging and assembly issues - To my dissatisfaction, it arrived with a broken air filter and some loose items rolling around in the air tank. No, it wasn't the air filter parts, it was something metalic actually inside the closed tank! Amazon referred me to DeWalt who referred me to my local service center.

Thanks to Amazon's incredibly fast and hassle-free process for returns, I had my replacement compressor less than a week later. Unfortunately, it too had a broken air filter. But since everything else was fine, I bought a filter locally (DeWalt's replacement has yet to arrive) for $10 and kept the compressor. This was not in the first shipment and is REQUIRED before starting the unit which is something that as a first-time compressor buyer, I would not have known to do. That kind of transition can lead to inconsistencies in fabrication and packaging like I have experienced, but I'm hopeful that the core design and construction of the pump and tank is solid and I like the way the machine works so I'm keeping it.
