compressor question

[Hemi-T]

As a side benefit, now that I have 220v in the garage, I can also use my welder and my powder coat oven out there. I garbage picked an old electric kitchen oven for free. Hard to beat for the hobbyist powder coater.

well i guess "experience is the best teacher" even when it is someone else
thanks a lot guys
P.S. do bolt feet to floor, or does the unit stand o.k. on its own?
i have not seen one over 60 gallon on wheels.

Uusally you can just let it stand on the floor. However some people choose to bolt it to a wooden skid for easiar moving with a forklift or making it easiar to slide.

Traditionally compressors are botled either to a skid for maneuverability or for sake of absorbing vibration. You can also pound some 3/8 X 3" concrete lags through the available holes into the floor, but put a block of rubber down sandwiched inbetween the two. Standing on concrete for hours is bad enough without all the vibration going to your feet

how noisy is 220v compressor (not oil-less) when it is running in confines of 20x20 garage?

[non-stick]

it's got a good hum to it, lol... that's for sure. After a while I guess you get used to it and it just becomes one of those acceptable background noises. This is why I always suggest rotary screw type compressors as opposes to piston type. A little more expensive but the added bonuses are sooooo worth it. Quieter, quicker reclaim on lost air pressure, ease of maintenance,etc. Of course... they cost a wee bit more. There's no major difference between 115V and 220V as far as sounds goes, I believe. Noise is noise, so they say. Perhaps a decibel here or there, but you'll not notice the variance.

hmmm, decisions,decisions,decisions

cheers & happy thanksgiving to all

If you get a quality brand compressor, chances are it will be a lower rpm motor....between 1250-1725 rpm or so....this will actually be a bit quieter than a 110 compressor which usually run at a real high rpm to make up for its lack of power. The lower the rpm, the longer the life and quieter it is

Running a outlet for your a equipment and having it hard wired is a great idea but dont do it becuase you think it will have a problem running on a extension cord. The trick here is not to use smaller wire than you are plugging your cord into and making sure you put a bigger breaker in that will carry the extra load (if you have to at all). I know we have all used an extension cord at one time or another had had it get hot especially those 50 to 80 fts. the reason for this is not the lenght of cord but that the cord is made of wire that is smaller than what it is plugged into. (yes I know that their is more too this and eventually on very long power runs you need to go bigger to maintain line consistincy but I am assuming your not trying to run down to the end of your 400ft building and put a compressor in the farthest corner)
Just think of a cord or hard wire outlet as the same as long as you use the same or bigger wire.
I use cords for everything be smart and dont over load your system and you can run a cord quite a ways.
with a cord in the garge you will find it nice later when you add a arc welder wire feed hot tank etc. I use a 75ft cord just on my miller 210 wire feed alone. without the reach of the cord I would be limited to what I can get to to weld.
also another thought that just came to me is a gas powered compresser my brother has one of these at his house. works great and he can take it with him when he needs to. a small gas compressor is a few horse power right out of the gate and they have very fast recovery. he actually has a propane tank he bought at lowes or home depot (100 gallon). he just tied the tank into the system and it gives him a tremdous amount of voume and he has no problems at all blasting. (he is a plater)
by using a propane tank you can have a bigger system for less money. Its always cheaper when you do it yourself. well most of the time.
one last thing that i think everybody could benifit from is a good line air dryer. I am a diver and use a hooka system on my boat. hooka is where you are connected to a compressor all the time so you do not need tanks and you can stay as long as you like under. so for a air dryer in the compressor we simply go down to the home depot and buy a 2inch copper pipe about as long as two tampons long and the end peices that you solder on that gives you threads on both ends and also the caps that thread onto the ends that make it look like a pipe bomb. now just drill and solder one brass air line fitting in both end caps and connect it between your line and compressor and stuff it full of tampons loosely ( nut snug). This will give you two things the best dry air you could ever have for a few dollars and a reason to kepp the wife. no man in his right mind would ever go into a store and purchase tampons.

thanks 11111111
i had thought of a gas unit, i guess you would have to have it outside as the noise would deafen you, or is there some way to suppress the noise? & then there's the neighbours to worry about if you can't quieten it down,the mobility aspect has my interest though.
are you diving abs, or do you do salvage work?
