Air Compressor, 225-PSI Max, Hand Carry with Wheels, 4-1/2 Gallon (D55146)

Thing is awesome fits in my sedan car ran my framing nailer and other high demand tools got referbished renewed option and looks new to me

Very reliable product My last one was leaving fine since 2015 till 2025 only reason for purchase new that my old one stop automatically shut off, otherwise is lifetime proof compressor

I got the compressor in about 2 days, seeing as it came from North Texas, so yay Amazon! After reading some of the reviews, I was a little weary, but it looked in new condition and all the knobs and switches worked (on/off switch seemed oddly loose, but I think that's by design). BEWARE!!! I read the English part of the manual cover to cover, and there was absolutely NO MENTION of the "break-in" procedure; thankfully, at least one other reviewer did mention it so it made me suspicious. Upon going to the DeWalt site and downloading the manual for this exact model, I did find the section for the break-in period, and it even warns you NOT to skip it (basically run the compressor for 15 minutes with the drain plug open and then close the drain plug to let it come to full pressure). I did use the compressor once to run a nailgun, and it worked pretty well. Not as quiet as some, but certainly not as noisy as others. Other reviewers were correct about having to tilt it 45 degrees in order to drain the tank; it even alludes to that in the manual. I did notice during the break-in period the tank got hot (or at least very warm); I don't know if that's normal or not, my last compressor didn't, but I don't think I ran it enough for that to happen. I also did opt for the 300 psi rated hose, but I got mine at a local store. Make sure you get some 1/4" quick disconnects and make sure you get at least a 3/8" diameter hose (the diameter bit is straight from the manual)! So far, I definitely like this compressor (oil-free rocks!). I took one star away because of the seemingly missing section of the manual, which is my main concern right now. I will post an update if I find out anything new about this, but for now, here is the link for the manual from the Dewalt Site: UPDATE: 8/12/2015 As I was reading through some of my old reviews, I realized I've had this thing for 5 years! Still going strong, and I while I don't use it every day, it's there when I need it. Only thing I've had to do so far was to replace some seals (easy, with a kit) on the knobs. Definitely glad I got this thing. [...] EDIT 7/21/20 I've had this for 10 years, and still working! I had to rebuild the seals (easy procedure), but the compressor still runs! Great buy.

So-so on this beast- There has been a disturbing trend in tool design lately- TOO heavy duty. My theory is that so many people have been burned by cheap and flimsy tools that tool designers are trying to be the beefiest, heaviest, most “heavy duty”- looking in the store. But for those of us who use tools every day, this beefing up is starting to get in the way of actual utility. Kobalt is the leader in this category. The best tools are strong AND light. And functional, designed with the user and task in mind. When it comes to power tools, true “heavy duty” is on the inside- bearings and switches and lubrication and sealing against dust and so on. This compressor, unfortunately, is of the overly beefy variety. It’s only problem is that it’s just way bigger and heavier than it needs to be, in a bad way. It’s all a marketing gimick to convince you it’s heavy duty. Let’s start with the power cord- it’s the diameter of my thumb. This thing is meant to be used on a normal 15a circuit, it doesn’t need a power cord that’s as thick as a 50a range cord! For prevention of cord damage, I’d rather see a replaceable/detachable cord like the ones on some older Milwaukee tools. A peak inside reveals another waste- the motor/compressor is about 12 inches away from the tank. Why? That’s 12 extra inches of steel bar and hoses and space in the truck wasted. Ease of manufacturing, maybe? Just to make it look bulkier? The extendable bar handle was a good thought, but it doesn’t lock into place, so the unit can’t be effectively pushed as it just wants to collapse-which makes navigating stairs difficult. The wheels are pneumatic- again, a waste of space and weight. Does my air compressor demand a cooshy ride? Am I going to tow this thing behind the truck? I might have to, it’s so heavy. There are superfluous “roll bars” in odd places, like on the tank in the same place as the extendable handle. There’s a big steel plate on top that says “no step”... well then why is it there? Just for extra weight? Just a little bit lighter and the unit would be light enough for safely loading and unloading by one person, but they just missed it- it’s just a little bit too heavy. Don’t get me wrong, the unit seems good In other aspects; powerful, quiet, good regulator control, etc. However, the insecure, overcompensating “heavy duty” marketing-driven design is a slap in the face, although it may or may not be an accurate representation of internal build quality. Only time will tell. But right now, I’m wishing I had gone with the smaller, lighter, and cheaper Husky competitior.

La qualité

excellent produit, très bon rapport prix/qualité, on a travailler a quatre hommes avec des outil a air sans aucun problème. pour construire deux maisons.

Excellent compressor. Great price.

Box that the compressor came in was in really bad shape and there was no manual. I found the manual on line and printed it. The compressor is very good, powerful and quiet enough that I don't mind running it inside my house. I bought it mainly for reshingling my house next spring but the price was really good so I bought it now.

Work well so far nice product
