huge air compressor...

Its alive!!! This thing runs like a champ, i wired it up just like you said, motor to regulator, regulator to load. then grounded the motor out to the tank. it may be the quietest air compressor ive ever heard. the only thing i gotta do now is figure out how to plumb the rest of it in, and get rid of the mountain of rust on the bottom
 
Just make sure there's a ground path from the tank and motor back to the breaker panel. The ground is basically there as a safety in case something fails and shorts to the chassis... keeps you from getting zapped.

As for the rust... the outlet on mine feeds from the side of the tank. I've got a length of 1/2 copper pipe running off the drain on the bottom to a ball valve. Works for draining, but also works to blow out any crap that collects at the bottom of the tank. Let it run up to full pressure and open the valve.
 
ran into another snag. I installed a pressure gauge on the side of the tank, to find out what im workin with here. Im assuming its around 200psi, but i wanted to be sure before i bought a drier, filter and lubicator, so that i dont buy a max 165 for a 200psi system. anyway, i put the side mounted gauge on, nothing happens. I open the drain valve on the bottom, easily 150psi comin out. so i took the gauge back and got another one, same story. there is a little pin lookin thing inside the valve on the gauge, is there a special fitting this has to be connected to in order to open that pin?
 
it looks like a normal gauge, and ive never heard of a special fitting to install it into, but i cant figure out why the gauge wont read. its a 0-300psi gauge.
 
kinda, but instead of having the pin sticking out in order to push the valve stem in, it is flush. does the gauge need to be in a T? Right now i just have it screwed directly into the tank, does it need to have air flow through it? this is how i have it now,


TANK----gauge
should it be like this?

The gauge should work either way, The gauge is just giving you the pounds per square inch of air in the tank, if you have it screwed into a fitting that allow air to flow out when the gauge is not plugging the hole, than it should work. Where did you get the gauge?
 
yea thats what i thought, but im just tryin to come up with ideas why it wont work.. i got the first gauge at lowes, 2nd at home depot, both made for air compressors, not for something else.

Barring both gauges being bad, is the hole where you have it screwed into, if you take the gauge out does it spew air out?
 
did the one on your other compressor have a pin in it too? I checked my gauge on my comp and it does not have a pin in the center. maybe the ones with pins in the center need a special fitting to go into?
 
Do the gauges look like this?

I was at Lowes today and snap a couple pics of them
 
im thinking that what it is. yes the other compressor gauge looked the same as the one i bought. both having pins in the middle. it looks like yours except the center isnt hollow, there is a tiny valve, almost like a special fitting needs to push it in. heres the picture of it. i looked for a gauge like the one you have, your lowes must be different cause all they have is my style. oh and it looks like mine is hollow, its not it goes down to a cone with a hair sized hole in the bottom.

well got a filter, regulator and gauge. the gauge tops out at 20psi, and very very slowly climbs. it took about 15 minutes to get to 20 psi. I opened drain valve, and it just about blew my arm off. still absolutely lost on ideas...

mmm i said this before but maybe that orifice is plugged up.. try maybe tee-ing in at the pump-> tank or put the connection on the bottom of the tank to test? or rather let me ask this.. are you only getting out 20psi of air at your regulator/filter setup?

also I looked at mcmaster carr and they don't sell any special kind of fittings for air gauges..
 
Plug the gauge nipple on the tank and plumb one inline. At least you'll know what your line pressure is.
