As topic says. Im confused if a lubricated compressor like most dental compressor will work. Cause i believe the sil air has lubricant in it but its a recommended compressor. Also wondering if these would work either.

Cause it says its oil less but here you can see what looks like a oil plug in the case.

The reason i ask about the ir is my dad has that exact compressor. And at 45cfm @ 175psi yes i said 45cfm :D and a 120gallon tank. I dont think it will run much when using the shoebox of it. lol

The problem is that oil mist is explosive. If it gets into the pistons and gets compressed, it ignites and could blow up. A kid was killed when he put a few drops of oil in the fill nipple of his paintball tank and then filled it up. The tank exploded killing him instantly. So that's why we don't recommend anything but oil free compressors.

Yes tom but i dont understand what oil free is...cause some compressor say oil free. Then you look into them more and they are lubricated compressors. Just like the sil air one i believe that you have a link to on the site. I think they use oil for lubrication. So it has to basically be a diaphragm compressor then?

If the compressor says oil free it doesnt use oil to lubricate the sealing rings. Most of these compressors us carbon fiber pistons and sleeves.

So as long as it says oil free. Im good to go. I was just scared if it said oil free but had oil in the crank area some how alittle could get past the rings. Anyways thanks tom for the help.

Here are some examples of suitable 'oil-free' compressors -

I bought that compressor (GMC 6310 off Amazon.com)
1. it IS oil free (does smell of oil though, presumed to be from manufacturing)
2. it IS very quite compared to the $99 compressor (http://www.lowes.com/pd_103500-43657-FP209599DI_4294795218_4294937087_?productId=120553 5&Ns=p_product_prd_lis_ord_nbr|0||p_product_quantity _sold|1&pl=1&currentURL=%2Fpl_Air%2BCompressors_4294795218_4294 937087_%3FNs%3Dp_product_prd_lis_ord_nbr|0||p_prod uct_quantity_sold|1) that I will be returning to Lowes.
3. It does not come with any air hose.

I have not used it yet with my Showbox and will post up a review once I do so.

Just picked-up the RIDGID Tri-Stack Oil-Free Compressor (http://bit.ly/RIDGID-Tri-Stack-Compressor) today at Home Depot (http://bit.ly/RIDGID-Tri-Stack-COMPatHD).
4.9 SCFM @ 90 PSI / 150MAX PSI / 5 Gallon Tank
Got 10% off using this coupon (http://bit.ly/HDmoving) = $257.84 out-the-door.

I'll be using it with my friend's ShoeBox compressor (and my booster) later on this week
(as I'm not sure if my buddy's shop compressor is oil-free or not.)

I'm also curious about acceptable compressors. I have a large shop type dual piston compressor which uses oil. I keep it below all of the access points in the system (it's in the basement) and the point at which I might be using the Shoebox would be about 20' away and on the other side of two water separators and a filter.

Is "oil mist" really something to be paranoid about in a situation like this? I'd hate to have to buy another, considerably inferior, compressor if this could be made to work safely.

I think this is all you need for Shoe Box Compressor. If I am wrong correct me. Harbor Freight $59.00. 100 psi max and just shy of .04 cfm output

I checked your link and wanted to chime in.
Yes you can use it because it does not use oil to cool the compressor pistons only the rest of the compressor.
It says "designed for applications where oil free air is required" in the description.

Aslo, Lowes has this one rated: .36 SCFM @ 90PSI

It comes with hose and 2" nailer for $79, but gotta hurry sale end today.
It goes back to $99 which is still a good deal.

I bought it, and filled my new 13 cu tank from empty in 20 minutes.
It came on 3 times for about 30 seconds.
