Installing a Quincy for shop air - tips and advice?

Hello
What are the best types of sealant do people use for installing a shop air system on Brass Pipe fittings?
My installer used Loctite 567 which is very hard to get! I ordered a tube of 50 ML on Mon Feb 28,2022 at it came today Sat Apr 2,2022! What happened to 2 day delivery?
Looks like the country of origin is China??
The tracking details in the Amazon order only shows the last 2 days when it first arrived in one of the Amazon distribution warehouses!
The support email is [email protected] ?

 

Great info - thanks so much.
This compressor works great! I just blew out the LT1000 tractor’s dirt and leaves. Also took off the blower and put on the mower deck.

Set the compressor on rubber pads and it should be fine. Tire tread sections work well. The deeper the tread the more cushion....

 

Good Idea, but since the compressor is 720 lbs I got the heavy duty OEM pads from Quincy but the installer said this unit is soo heavy the feet will still sink in. Therefore I ordered 4”x4” heavyGuage 1/4” steel plates. I primed and painted them to avoid rusting. We used the drill press to get bolt holes in the exact center and then using the special anchor set, bolted the leges thru the plates and thru the pads. So far so good.

 

As long as it isn't bolted to the floor, pads will work well. If bolted to the floor with pads, you just shot yourself in the foot because the bolts will transfer the vibration anyway.

 

I agree However, As part of the Quincy installation they bolt the compressor to the concrete floor so it does not move and break the pipe connections. They do not simply use bolts into the floor. They use special threaded rod anchors and nuts that are not tight so the pads have some flex to absorb the vibration. They have been building and installing them since 1919 so I trust their expertise.
On smaller compressors, it is also ok to leave the compressor bolted to the pallet but the pellet would not fit in my installation area.

 

Right. Bolting through the rubber can intensify vibration because the machine will hammer in an upward direction on the fasteners. Putting anchors in the floor and setting the isolators and feet over them with locked bolts or pins floating above the feet would be better.

I have been tempted to use magnets in opposing directions as isolators and use rubber retaining rings to prevent side slip.

 

Pads aren't as much for vibration as they are for support. Before rubber pads you went through a pia job of shimming and sometimes grouting.
I was stuck on a plane with a mechanical engineer insurance inspector. He mentioned that in ruptures, more frequent than you would think, bolted compressors cause far less mayhem than ones just sitting.

 

Hello
My take on this is that bolting the compressor directly to the concrete is not good, but using pads even these heavy duty pads is better but do to the weight, 720 lbs of this compressor that eventually the weight of small feet will sink into these heavy duty pads! This is what the installer had seen in his experience. That is why I added 10 gauge 4” x 4” steel plates to the the top of the vibration pads so the feet will NOT sink!
The bolts are not tight and this is what the compressor manufacturer recommends for their warranty.

 

Putting plates on top of the pads is a good thing especially if the feet are cupped. Little compressors like that are pretty accommodating to mounting issues.

 

Good point
It maybe that compressors that weigh more should have better and larger feet just like us Humans but I do understand it is not always cost effective and that is ok but there should be a recommendation! Luckily with the tip from my very experienced installer those 10 Guage top plates are the adjustment that were needed. ??
