Can’t wait to get this thing all hooked up.

Finally upgrading from a little old 10 gal compressor to this beast. 1.6 CFM was fine for filling up tires and running a blow nozzle, but I’m gonna have to start building up a proper air tool collection now.

Spent hours unloading this shelving unit and pulling it out of the corner to make room (decided no to cut shelves out from it after all) . I’m gonna box this compressor in, like I did with the old Campbell Hausfeld, but I’m sure it’s gonna take more than bath towels and cardboard to keep the noise down this time. Gonna have to figure something else out.

!!! UNKNOWN CONTENT TYPE !!!

So far, I’ve managed to build a small frame with rubber dampers for it to sit on, cut an air vent, and run wiring. Despite having thought far enough ahead to install a 220V outlet nearby, it’s just a little further away than I want it, so that’s turning into a junction box, with a new length of wire jumping over to another box closer to the compressor.

In the above pic, you can see an initial test fitting, but I’ve pulled it back out of that space in order to work on plumbing. Been getting by with running a 50 ft hose across the rafters to the hose reel, but it’s time to install a rigid, permanent system.

Copper would be nice, but I figured that would probably be expensive... Now PVC tubing seems to have good pressure ratings, but I shudder at the thought of something happening and sending sharp pieces of shrapnel flying. Metal it is, then. I hear that black pipe has a tendency to rust inside, so galvanized looks like the better option... Except that lo and behold: copper is apparently cheaper than galvanized, even if I use the thicker type L stuff! Well I guess that settles it haha.

Planning to run some copper piping, with valves, drip tees, risers, and install a water separator/filter and regulator just before the hose reel. This upgrade has been a long time coming. I’m psyched!

Make sure whatever type of hard lines you’re using are rated for air line use.  Just because it will handle the pressure doesn’t mean it is good to use for compressed air.  Also put a couple feet of flex line between your compressor and the hard lines.  You need something there anyway to get everything lined up easily and it will isolate the hard lines from vibrations.

Egg cartons should help.

Oh yeah definitely. Look ing at putting t y pe L (the thicker stuff) copper against   th e wall, with flex hose at the tank and at the hose reel. Not going crazy with a lubricator or anything like that, but I’m hoping that the risers, drip tees, and water separator will be enough not to need a drier.

Egg... cartons...

Interesting!  Never thought of that.

Nice! I have the smaller version of that and it is LOUD. Part of my garage renovation will be to box it in for noise abatement. It seems the only time I really have to work in the garage is when my girls a napping, and their bedrooms are directly above the garage. The compressor hasn’t been used since we moved. :(

Yeah, found this one on Craigslist and got the seller to leave it plugged in for demonstration before showing up and purchasing. It sure is loud! Not sure how much I’m going to be able to do about that, but I want to at least take the edge off.

Oh and I finally got my hands on a decibel meter to prove how effective the old 10 gal’s sound box was. The compressor runs about 70 dB, which drops down to about 60 once boxed in. That comes out to about  50 dB if you’re standing on the opposite side of the garage, and outside it’s in the 30s. Haven’t measured the 60 gal yet, but I have a hunch it’s probably somewhere around 100 dB.

Very nice! I’d probably try 2" rigid insulation to box it in.

Would that be too rigid? I’m sure it wouldn’t echo as badly as the wood, I just dunno how absorbent it would be.

Similar in construction and material to the stuff you see in band rooms/sound rooms...that kind of stuff. Egg cartons and some foam behind it would help cut down on the noise. Gotta be the cardboard type though.

If effective, this is very much the style of solution that I’d love to go with. It cost me $0 to throw together some old bath towels and cardboard for the little compressor, and I ’m really pleased with how that turned out.

I honestly don’t know.

I didn’t get any measurements of mine, but at my old house I just had it inside a closed closet in the garage. That took it from my-ears-are-bleeding-and-so-are-the-neighbors’ levels down to a much more tolerable level. I think I’ll apply the same treatment with some eggcrate foam inside the enclosure. I’ll have to figure out how to get it some ventilation, though. I never ran it hard in the closet, but after a couple of cycles it would start to get a bit warm.

Y eah, you definitely want some ventilation there. My little 10gal was up near the soffit, but I never did get around to cutting a high-point vent to help the hot air escape . I never noticed any performance issues, but it was all boxed up there so I never checked to see how hot it was really getting. FWIW,  I was only filling the occasional tire and using a blow nozzle...

This time around, I’m venting it directly outside (fortunately the closest neighbor is over 300 ft away w/ plenty of trees between us ).

Very nice. My 60gal IR is very loud but I can deal with it, doesn’t run much. I have a 2' section of flexible line from the tank to the wall, with black pipe hardlines (including drain Ts). I’m not too concerned about potential rust in the lines; with the Ts (I put ball valves on the bottom) and the filter/regulator being after all the hard line, there’s not much risk.
