Air Compressor reserve tanks

[DiverRay]

Rob,
Try putting a rubber grommet on TOP of the compressor mount bolts. You should "sandwich" the legs in rubber to cut vibration. All you will need to do is loosen one bolt at a time, insert a grommet UNDER the flat washer, and re-tighten.

Hockey pucks!

Hi Rob,
DiverRay is right but I'd go further. Buy as many pairs of hockey pucks at a sporting goods shop as your compressor has legs.
( Looks like the tank has 3 legs, so 6 pucks) Drill them through to fit the hold-down bolts.
One goes under and one goes over each tank leg. You may have to hacksaw the top ones D-shaped.
Jack up the compressor, remove the square things, substitute the pucks, put big washers atop the upper pucks and reef the nuts down.

When I read the post about the use of hockey pucks I was thinking that they are rather hard rubber so I bough those compressor pads at the compressor shop. There are med density rubber and cork. I am sure the issue is in fact that the vibration is going through the anchor bolts which are of course in the floor so ... The next time I am out at the fasteners shop i will see what they have in the way of grommets that can be used to prevent contact at the sides of and through the tops of the bolts.

Hi Rob,
a quick Google-search found these things:-

A better answer than my own Mr. Cheapskate solution of stacking up old hockey pucks or discs cut out of used industrial floor mats.
Mind you, the bought ones do have to be paid for.
BTW, got my own compressor up and running again just in time for my youngest to use the air tools to change out his car ball-joints.

Well they look pretty high tech don't they? I was talking to the lad at Bytown Auto Propane the other day and he uses hockey pucks under the feet of his bigger 2 stage compressor by the unit is NOT BOLTED to the floor. I am now sure that the issue I have is the fact that I bolted mine down. I'm going to start by using XS11 engine mounts to sandwich the feet in place like grommets. If that fails it's OFF with the bolts and I will put in on a short leash :-)

Why did you bolt it down?Was it walking across the floor?I have mine sitting on the floor and have never had a problem.

My garage floor has a pretty good slope to it and I figured it would be moving down hill so I fastened it to the floor. I may just set it on a rubber outdoor mat.

In my opinion, it is best to hire an electrician for your installation. All the advice in the world is useless if it results in a house fire or invalidated insurance policy when you need it. Internet electrical advice has to be one of the worst ideas going, no offense intended to any of the previous posters. Bolting the compressor to a floor that isn't level can lead to premature tank failure. I have seen a 120gal air tank fail in less than one month due to stress induced hairline cracks about a foot long produced by bolting the tank to floor that was not level. Normal running vibration did the rest. Hockey pucks worked well for vibration isolation on many installs for me, up to 220 gallons and 30hp. Leaving it bolted to a skid is another idea. Unless it is leaking a lot of oil the skids last quite awhile. I wrenched on compressors full-time for over 10 years, now I tend just one in an air supply plant for a blowdown windtunnel.

The compressor you bought is built by a company called Laplante compressors in Hong Kong. It should do you fine, but Princess Auto are terrible for stocking replacement parts (8 week wait for a replacement flywheel for instance). This is a single stage machine, as you can tell by the identical sized cylinders and the fact that each is drawing in air from atmosphere and pumping to full tank pressure. This limits you to about 125psi or less, as single stage pumps rapidly lose efficiency at higher pressures due to excessive heating of the air. They do produce more air at lower pressure than a similarly sized 2 stage though. More stages are required for higher pressures. The centrifugal unit I work with has 10 stages to produce 300 psi. It makes 40,000cfm.

It was a rule of thumb that compressors draw at least 10 times the rated current on start up, some were worse, some were better. Time delay fuses were usually required due to the fact that this load was sustained for longer periods with a compressor than with many other types of machinery which tend to spool up faster than a recip compressor. It is best to lengthen the hose/pipe than lengthen the wiring. Keep the electrical supply lines as short as possible.

Most likely this is about a 3hp unit, which is about the max you will run on normal household service, and which is why you always see some cop-out rating like "Peak HP" or air delivery ratings at 40psi, so they can claim it is more powerful than it actually is. Campbell Hausfeld was successfully sued over this a few years ago.

You should be satisfied with your machine. For the money, it looks pretty good.

I leveled the compressor at the same time as i mounted it to the floor. that was also part of the reason i wanted to mount it. So it would stay level. I am content that it is wired safely at this point in time.
Thanks to everyone for their input on this setup.
