I have added photos of the compressor and the pressure switch.

You are going to have to remove the shroud covering the guts to find it. Given the size of this air compressor, it is not a more traditional pressure switch.

Cheers,

Airmate by Emglo - compressor wont start at all

by bdawg
(stockton)

I have an Airmate by Emglo 1 1/2 hp, 200 psi portable air compressor that was my dads, has been in storage for 2 or 3 years worked fine before, now when i turn it on, the motor humms for maybe 30 sec or so, then the motor reset fuse pops....?
_______________
It worked fine when it went into storage, but hasn't started properly since you took it out?

I think this compressor is oil lubed. If so, is there oil in it?

If oil in it when it was stored, and that oil has dried out on moving parts, that might be it.

If all parts move OK, then I'd next look to the capacitor to see if it's working OK.

Cheers,

Bill

first outlet
by: Anonymous

Bill, I have owned one of these for years. Even when it was brand new it always started and ran best on a 20-30amp breaker. If it is plugged into an outlet on a 15amp breaker make sure it is the first outlet (which is usually the closets outlet to the breaker box) in the line. If you get that thing in this location and it still pops its' breaker button then you want to try getting the air compressor warm. This compressor always has given me fits, I should have given it back the first day.

my emglo air mate electric compressor will run but won't build pressure above 20 psi ,.

I have an emglo air mate electric that i havn't used in about5 years, it will run and build up to about 20 psi and won't build tank pressure any higher.It's missing the air intake filter which i need to replace.

Rick, the first thing I think of when I hear about an air compressor not building pressure, is the valves.

Since you lack an intake filter, it's pretty easy then to feel up around the intake (carefully) to see if the compressor is pulling air in when it is running.

If so, then shut it off, dump all the air, pull the line from the pump head to the tank, and then start the compressor.

Is air coming out of the high pressure port (where the line was connected)? If so, can you stop this air by pushing a gloved finger over the port?

Post your response as a comment here, please and we'll press on figuring out your compressor problem. Also, look at the Troubleshooting category on the site map page for links to more pages with info.

Cheers,

Bill

fixed, thank you
by: rick

Thank you for your help, it was a cracked valve under the head, made one out of a hack saw blade.

Good for you Rick. Please let me know how this works out, as many other folks have been searching for a good metal stock to replace valves.

How to turn up tank pressure?

by Kyle

How can I turn up the tank pressure on my 4 gallon twin tank emglo compressor? I have the regulator set on 110 and the motor doesn't kick on until the tank pressure reaches 100 psi. Any suggestions?

_______________________

Kyle, unless there is something failing on your Emglo air compressor, the cut in pressure level and the cut out pressure level are factory set.

To me that means that the settings are optimal, set by the factory, and the air compressor will run best at those settings.

If you would like to increase the cut out pressure, recognize that in so doing you will likely overload and ultimately destroy the compressor.

If you increase the cut in pressure, the lower level where the compressor restarts, then you are possibly not going to allow the compressor time to cool between cycles, and that, too, will ultimately damage the compressor.

Having said all that, the device that controls both settings is your pressure switch, and that info is covered on the PRESSURE SWITCH page.

Cheers,

Bill

I was using my compressor and a rubber air tube is now having the air come out it and the unit will not increase in pressure.
Do you know where this hose goes. It is rubber.
