I remember when this NG was full of useful info apropos its title. Desiring
to be faithful to that memory, I'd like to relate this. Yesterday I brought
home an Ingersoll Rand type 30 vertical compressor (99.9% metal and lots of
it). Was considering how to bolt it down to the concrete garage floor with
some kind of isolation pads. I hadn't really thought of something I could
purchase locally so I could get the thing operational and decided to wander
around Lowes in hopes of finding the right solution. I think I came up with
a winner and it may be of use to anyone in the same circumstance. Somewhere
in the hardware isles you'll find chair leg tips, gliders, rubber feet and
the like. They have these Waxman Super Sliders that seem perfect for
mounting just about anything under, say, 1000lbs. The ones I got are 3-1/2"
in diameter and are about 5/8" thick. They have a thin felt layer that I
don't care about but otherwise they're made of some very dense foam which
only compressed slightly under the considerable weight of the compressor. I
haven't bolted it down yet but I did run the unit with these things in
place. The compressor was much quieter and you couldn't feel the vibration
in the floor at all.

Sounds like a winner. Considering they are foam, it might not be necessary
to bolt it down.

If you don't use similar isolation if/when you bolt it down, some of not all
of the vibration will return.

The one I used with my vertical compressor was called "plush carpet".
It worked great.

Plush carpet also works great. McMaster has pages and pages of
isolation pads.

Hi Nok, nice idea you wrote above.
Another alternative is as follows. I have an 80 gallon 6hp 2 stage vertical
compressor. Concrete floor. I simply placed a piece of rubber (old truck
inner tube, free at your local tire store) under each foot. Then, to keep
it from walking around the shop, I drilled a small hole in the concrete
under two of the feet only. Within the holes I dropped in a phillips
screwdriver (they were to be tossed anyway). The compressor runs quietly,
doesn't vibrate, doesn't walk around and can be moved out of the way by
simply unpinning it (two screwdrivers).

Works great but be sure to take a look at the foam thickness every few
months to make sure it is not compressing. Most of the closed cell foams
will eventually sag to almost zero. Better yet, measure it to see how
far it has moved.

I made some of these for my 5hp 60 gallon compressor. I find they are too
stiff to do much for vibration on something that light weight. Also they
allow the machine to move a little each time it starts from the sudden
torque. It desn't move when it's running though. A layer of something
more plaible in contact with the concrete may stop the walking around. I
just haven't gotten round to it yet...

One of the best isolators is cork, unlike rubber it becomes less stiff
at high loading. Similar stress-strain curve as copper. Recommended
pressure is between 7 and 20 PSI. Thickness between 1" and 6" . It does
need an inertial mass such as a concrete slab or block between the
vibrating machinery and the cork.
