Question: Does a air hose come with the item purchased? If so, how long is it?
Document: I will update my review as I find more positives/negatives.Forgot to mention...it is not recommended to use an extension cord with compressors in general, although this one says its OK to use a 12 gauge or larger for a max of 50 feet. Unfortunately my garage is about 75' from my house with no designated line. I may need to either try and use a 12 maybe even 10 gauge extension cord and hope motor doesn't burn out OR use a long air hose.
I purchased this air compressor about 3 years ago and it has been the best air compressor I've ever owned. I bought it to replace the Craftsman compressor I had and it  is  quiter than the craftsman.
THIS Item Works Excellent. You Can adjust The Output Pressure. The Unit Really Does The Job Of A Commercial Unit. It Works great With Any Air Tools. It Comes Well packaged. No Sales Tax And Free shipping. It Is just The Right Size. I Have Not Been Able To Over Use The Item It Keeps Up Extremely Well. There Really is No Difference Between A New Unit And A Refurbished One. It Has The Same Warranty As A New One.
It works as advertised! It is a lot quieter than my old air compressor. It would be nice to have a hose reel on it.
The Dewalt D55168 air compressor doesn't take up much garage space, and is not as noisy as other brands. I purchased this factory reconditioned compressor mostly to fill a portable air tank used for adjusting the tire pressure on our vehicles but also to be used to run some air tools occasionally, etc. This compressor is continuous duty, but the instruction sheet advises not running the compressor more than 35 - 40 minutes each hour to extend the compressor life.
I've had my compressor for about 6 months now. I use it primarily for finish nailing (low air consumnption), and also for dlowing out the dust in the shop (high consumption). The unit is well constructed, and the design is good. The "handle" on the front is designed to protect the control panel and your hose connection should the compressor be tipped over for any reason.
The Dewalt unit does not. In fact, aside from draining the tank (i.e. letting the air out) at night, there really isn't anything you have to do.The Dewalt D55168 compressor is rated at 200 PSI - however, that's tank pressure, not hose pressure. In other words, you can't dial the regulator up to where you are supplying a full 200 PSI to your tools (nor would you want to).
It's pretty quiet. Can actually carry on a conversation within a few feet of the compressor while it is running. Also, it is well sealed. What I mean is that I charged it up to the max pressure, used it, then disconnected the hose. When I came back to use it 6 days later, it had lost no air pressure! Love that.Just one small issue to mention.
The power switch can be set to either "off", or "automatic on" setting which kicks the compressor on at 175 psi and kicks off at 210 psi. The compressor takes around 6 minutes to fill the tank, then turns on and off automatically as the air is used. The working pressure to the air hose is adjustable with a knob on the front panel where the tank pressure, and working pressure gauges are located.
This isn't any problem, however, since most air tools only call for between 50 and 80 PSI. Even when blowing out parts, 100 to 120 PSI is plenty. Basically, the pressure available at the hose is the same as most other compressors.This air compressor is outstanding for several functions. For filling up tires, it's great. For blowing out parts, it's wonderful. It's also perfect for running air ratchets and impact tools (such as impact wrenches).
Answer: yes
