Questions & Answers

Is it 1.8 hp or 1.6 and 5 CFM @90 or 5.2 @90

The picture shows its is 1.8 hp and 5.2 CFM @ 90 PSI but the specs show 1.6 hp and 5. CFM @ 90 PSI which one is correct?
Asked by: Brandin
It is 1.6 horsepower with a 4.5 gallon hotdog tank. It was $349. Well worth the money.

Has anyone else had the air pressure regulator go out on this compressor? Happened to me and several contractor friends

Asked by: Nick
Yes! Knob broke or stuck after maybe a dozen uses within 2 years.

Can this compressor be ran upright(storage position), as well as laid down or can it only be ran while it's laid down?

Asked by: Brian
It'll function in both positions but is not recommended to function in upright storage position and would risk in damage in low oil lubrication to cylinder.

Can use a 3000 watt digital inverter hooked up to my car to run this air compressor?

Asked by: James
Electrical systems on vehicles vary; please check with your vehicle's manufacturer prior to using any accessory/tool.

Customer Reviews

4.5 Gal. Portable Electric Air Compressor is rated 4.3 out of 5 by 93.
Rated 5 out of 5 by from Everything I could have asked for. When I was looking to buy a compressor, I was looking for something that would always have more power, functionality, and reliability than I would ever need. I never wanted to worry about whether or not my compressor could handle whatever I needed it to do, from filling up truck tires, blowing off a lawnmower, or running tools. I'm not any kind of power-user, just a diy-er, but I wanted something that was future-proof--I'm a "buy your last tool first" kind of guy. This compressor is exactly what I wanted. It has a large enough capacity, and fills fast enough, that I've never been out of air. It's simple to use, and reliable. And, even though I've only ever used one hose, it has dual couplers, so there's room for "expansion" of sorts, if I ever need it to do more for me in the future. This compressor is possibly the Dewalt tool that I use the most frequently, with the possible exception of my drill-driver. I've never regretted spending the money on it.

Rated 5 out of 5 by from air compressor:top of the line I am very happy with the new compressor. i started it right away and was suprised how much quieter and less vibration than previous brands, last being a 175max psi." Rigid" compressor with double tanks but one tank won't fill up and its loud and real shacky when filling. But the best of DeWalt is the fact its on its own dolly which makes the 90lbs feel like 30lbs and I don't have a problem getting it around since I recently had back surgery and can't lift anything heavy but I can still pull the compressor with no problem. I love it and anyone looking for a quality, dependable, powerful compressor then this is it, look no further. oil free too, one less thing to worry about. I know I'll get another one down the line if this one here goes bad an the warranty is out but I plan on using this one a long time before expecting any setbacks due to DeWalts reputation an their other tools I've used that have all been top quality.

Rated 5 out of 5 by from Well worth the price Had one of these compressors in the past and it was stolen, left my garage door open, Stupid me. The price may be a bit much but with the 200 psi and 4.5 gallon tank you will be free to use just about any air tool you can throw at it. I am a DIYer and do most of the remodeling of my house. I use it for all my nail guns, framing and finishing and also for bicycle tires. Allot quieter than the previous one I owned. The wheels seem to be a bit cheaper though. The last ones were rubber and the ones on the new one seem like they are plastic based. I like that there is very little to do to it when you take it out of the box. Fill the tires to 32psi and you are ready for action. Pretty much plug and play. I would recommend this to anyone who does allot of projects at home. Cant say anything about the pro users. Easy to move around and tucks away nicely in the garage. I chain it up now, LOL. Get it delivered to the store and pick it up. Saves shipping cost and it's not just dumped on your porch for someone to take if you are not home.

Rated 1 out of 5 by from Piston / Pump went bad - Less than 2 years old The Compressor worked Great for the first year and a half. Started to hear a rattling noise. Went to the Dewalt Factory and they indicated the Pump and Piston are going bad - Warranty is only for one Year. I would have hoped they Covered Internal failures longer than 1 year..

Rated 5 out of 5 by from At last a well designed compressor for all occasions...almost This compressor performs as described...but working with it is an even better experience. I want to emphasize that I am not happy with most Dewalt experiences I have had in the past. This compressor however was designed to fit the need. I am using it for everything FRAMING, SIDING, ROOFING, TRIM FINISHING. It is not a portable compressor, it is a transportable unit. I have set it in a work area and can get to anywhere I need to with 2 50' hoses. I can also move it closer if I need to with a 50' extension cord. Yes it is very quite but most of the time it does not matter because it is so far away I can barely hear it My old Emglo had problems not starting up soon enough and forced me to hammer the last nail in before it started up. This unit starts up way before you reach your limit. Even with 2 nailers going all nails are equally punched in. Don't try to save a few dollars on a cheaper compressor. Get this compressor and never look back. I picked it up on special just over $300.00

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 1 out of 5 by from 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.
