Thread: Compressor Mounting

Tweet

I've just finished building my dream garage.

Bought my first "real" compressor.


How do I mount it to the floor ?

Drill holes with masonry bits and epoxy studs into floor, then bolt compressor to floor ?

well that will work. any way you can secure it, you will be ok

Studs are a pain since you have to lift the compressor over them

Easier to go to Home Depot and buy lag shields (the lead anchors) and drill for the appropriate size. Get the shields and the appropriate lag bolt. Also, pickup some 1/4" or 3/8" thick rubber pads to put between the compressor leg and the floor....makes it a little quieter. Set the compressor where you want it and mark the floor for the holes; slide the compressor away and drill.

Dont forget to accommodate a drain valve on the bottom of the tank. Screw an ell into the tank and run a line out to a valve so you can drain it without crawling to reach under the tank. We ran our drains thru the wall so we can scare the rabbits outside when we blow off the water.

If it is fairly big size..........60 or 80 gal. tank you might want to put a 1/2" rubber insolator (for vibration) between the tank & the concrete floor. This will save you some hassle down the line.

That's what I did!!

Thanks Mike !

Where do I find these "lag shields" at HD, do you think they'll know what I'm talking about if I ask for them ?

And how bout that 1/4" - 1/2" Rubber Padding, any ideas where I can locate some of that ?

Thanks All !

Here is a picture and install instructions.

Yes, even the Home Depot zombies will know what you are talking about. As for the rubber pads, go to a rubber supply and get enough rubber to make some 3inch squares ......if you have a three legged compressor, make three. Cut the hole in the middle for your lag bolt. If you cant find thicker rubber, stack a couple of layers up. Graingers sells machine mount pads with the hole in them.... I think they are 4 inches square.

The lag shields and bolts should cost less than $5 and the rubber pads about the same. The most expensive part is the concrete bit to drill the hole.

mike in tucson is right on..........get the machine pads from grainger........you'll be happy that you did.

You may laugh but---The first time I installed my compressor, I lagged it to the concrete garage floor, and it made everything in the garage vibrate, and was terribly noisy from "resonance". I researched a bunch of different "anti-vibration" mounts, and they were all painfully expensive. I had a bunch of old chev small block mounts around---(they have an insulating neoprene bonded to them to keep engine vibration away from the car chassis), so I lagged one part to the concrete floor and bolted the other part to each foot of the compressor. Many, many, times quieter, and no vibration at all afterwards. (Take a look at the rust and then tell me its not humid in central Ontario.)

And tighten them each an equal amount,not to loose,not to tight,,,,you'll see what I mean when you start it.You can also get vibration isolators for the line if needed.I use that because mine is in my basement and noise travels outside and I don't want the neighbors to know when it is running.

Go to your local sports store and buy hockey pucks. They're firm rubber, and work perfectly as insulators for a compressor.

Dam Henry,,,I'll just mail him my womans biscuits they have been called called hockey pucks more than once!

I put anchor bolts in the floor and laid down some 3/4" thick rubber pads then scooched the compressor over the bolts and dropped four more thick rubber pads over the bolts and then put the nuts on with fender washers. Well isolated and no vibration in the shop. A single piece of 3/4" hose connects the drier to the wall plumbing. I used a lot of isolation valves and copper tubing to plumb the shop. There is an electrical box and air drop every eight feet around the shop four feet off the floor. Plus an electric and air reel in the middle. I hate extension cords and hoses. Sadly, I did not add the auto drain until afterwards so it was pretzel time when I put it in. Added auto drains to the filter units too for pure laziness.

Great ideas guys, I will definately use some of them when I mount my compressor. Currently it is still sitting and working on the pallet it came on. My eventual plan is to mount on the corner of the driveway outside the shop, then build a small shed around it with an access door using the shop wall as one wall of the shed. I figure that will isolate some of the disturbance it creates. From there I will run the plumbing inside with the appropriate drops and drains.

I used shock absorber rubber grommets on the last one I mounted in a truck, one under, and one on top of each mount leg. But, I think Brian has the best idea, only I was thinking of the "donuts" like old ford motor mounts, or the front mounts in my '59 Chevy truck.

I never took mine off the pallet it came on. Been that way for 10 years. works great.
