Question about Dewalt Air Tools & Compressors

1 Answer

How to change Emglo air compressor from 220v to 110v. Compressor is running at half speed when plugged into standard wall outlet. I bought the compressor new in the early "90's" and since then have heard other Emglo (same model) run on 110V. And they run twice as fast as mine. I believe I bought one that was already wired to run at 220V. Any help you can offer would be appreciated. TXS, Pete

Hi Pete,
On the side of the motor on the label should be a wiring diagram. The diagram will tell you how to wire fro high 220v and low 110v ...
If the nameplate is single voltage only then the motor cannot be rewired for the lower voltage...
Also check the motor RPM nameplate as compared to the others...you may have a 1725 motor and the newer ones a 3450 motor...that would give them double the RPM's if the gearing or pulley sizes are the same...so.. if you have the right voltage and the RPM's of the motor are the lower, then you possibly could change the pulley sizes to speed up the compressor...

Lots to check and think about...

Not enough electricity to run my air compressor


If your compressor runs on 220V and you only have 110V service where the compressor is located, you'll need to contact an electrician to set you up a 220V service.

I accidentally plugged in my pulmoneb in a 220v outlet


plugging a 110v device into a 220v outlet is not likely, as the plugs are a different configuration. In the event that you somehow managed to do that, your device is probably fried, as that would be to much voltage. Hate to say it; but you are probably gonna need a new one

How to use it if we have 220V outlet?


If the AC unit is 110V then you must plug it into a regular 110V outlet. You cannot plug it into the 220V outlet. Either get a bigger 220V unit or use a 12 gauge extension cord to get it to a 110V outlet.

I have a compressor that is wired for 220v however I only have 110v receptacles in my garage. This is a rental and running a 220v receptacle isn't an option. My plan is to change the cord from the...


The link below explains the extension cord requirements / amps. According to the chart, 14 gauge is good for about 50 feet, however you could bump-it up to 12 to be on the safe side. If you have a dryer plug in the garage or close, you could share that plug when not in use. Go to electrical supply house (or Lowes) with drawing of the plug /outlet needed and buy the components to make cord. If you have a 115v plug in the garage with its own breaker at the panel (plug with direct wiring to the panel) you could have an electrician convert it to 220 very easily. Good luck with your future projects.

Mdl.919.165250need to change wiring from 110v to220vshow wiring diagram for compresor


Your compressor was made by Porter Cable for Sears. The motor / pump is used on many different compressor models depending on tank size and style options. None of the models /including yours/ were ever designed for 115/220v. I did happen to see a compressor that was built for european destination that was 220v. It was easy to identify because it had a two round prong male plug (it could not be wired for 115v however). Good Luck

Electric Motor running slow


Century / Magnetek motors are used on many compressors but usually is an upgrade to have the option to easily switch from 110 to 220. Dewalt, Rol Air, Jenny, Emglo and others are considered high end compressors and come with switch for selecting voltage. One still must change the cord if selecting 220v setting. One thing in common is that 115v motors are never more than 2-3 HP because the amp draw for anything over 2hp is likely higher than 20 amps and would trip most common outlet breakers. You noted that your motor sticker lists 6.5 hp at 15 amp 220v so it could not work with 110v because it would draw over 30 amps and just not be practical. Magnetek motors are very good quality and most always state on sticker 110/220v and show wiring diagram for proper connection. Your compressor was most likely built to be stationary and be hardwired into an outlet/switchbox with heavy duty wiring or special cord to run such a high hp motor. You made a great buy however, because the motor alone lists for several hundered dollars alone. You could replace the motor with a 110v but you would loose the fast performance / recovery of that 6.5 hp motor. Like replacing a v8 engine with a 4 cyl. but expect to pull same load, not likely. Good luck with your purchase, and post again if you have other question.

For a/c unit, is there an adapter available or do I need a new plug cord


Actually you should buy and install an AC wall outlet. An AC uses more amperage than most any other appliance due to the fact it has 2 motors the compressor and the blower / fan motor. An AC wall plug has larger terminals so that the plug does not ever heat. Changing the cord to a different and smaller terminal plug is a bad choice due to the danger of overheating the wall outlet terminals. You can buy the AC horizontal terminal outlets at any hardware store. Unless you have a 110V AC unit you will also have to run a 220V #10 Romex (3 wire) with ground to the outlet to be in code.. An AC unit 1 HP (10,000) BTU or larger requires over 15 Amps for start up. Those that are 20,000 BTU or larger obviously require more than 15 amps as a power source.

Thanks for using FixYa.

Change from 220v to 110v on air compressor


I can't blame you for askig, but here's my response. 5 HP is 3750 running watts. or about 35 amps at 110 volts and it would take somewhere around 50 amps to start it provided the motor could even be wired for 110 which I don't believe it can and for that exact reason. I'm sorry, but it's just not practical.
