GLOAT bought Quincy air compressor

[yota]

whatever it is it looks top shelf. that 3 phase motor may be nice for something with a VFD.

Many commercial compressors use a VFD to control their speed/air flow. I’d see if there’s a controller you can get that would do that for you. Will make it much more efficient.

I just got this for $111 (plus 15%)

Machines Used | Quincy 5HP Air Compressor with Kruge-Air 80 Gallon Tank

Its 3 phase motor. I will change it to single phase.

Anybody think I paid too much?

I think this guy's a few short of a six pack. A nice way of saying you can't fix stupid. Mike

Speaking of Harley, have you seen this video?

He’s probably going to make 5x the value of the bikes in revenue short term.

He’ll be the next wheezing diesel.

Looks like a Quincy to me-older model with no filter cartridge. Binks also used Quincy QR for their compressors. Rebuild kits are decently priced and it is easy to remove the valves and dunk them in Evaporust and clean them to like new condition. The old Quincy compresser allowed for a wide range of speeds so a VFD can work nicely. You can dial in the speed you need for cfm and the slow put put sound is actually kind of calming compared to the horrible noise of most compressors. Dave

Yep, I'd rather have an old quincy than a new almost any other brand.

I got an old 10 Hp QR325 about ten years ago. Rebuilt the head and added a VFD. Runs like a champ and is quiet. Bet it will FAR outlast any new unit.

This one is destined for my winter shop after a rebuild. I am leaning to single phase because a 5 Hp motor is way cheaper than a VFD. May change my mind here.

Usually not one to recommend cheap VFD's for use on compressors as most go up in smoke under heavy loads, but may be worth trying as a lot less than a new single phase compressor rated motor. Also easy install, if everything else is working well. Most compressors work over a defined speed range, limits on the low end is lubrication, but running at a say 60-70% can make them quite a bit quieter along with adding some baffling to the intake air filter. Automation Direct tends to stand by their products, other two you would need to check on warranty. But at $300-400 and not having to deal with replacing a good 3 phase motor would seem to be a reasonable route to take.

I bought a defective Champion from university surplus that had a 3HP/ 3 phase baldor motor on it. I went even cheaper and bought a Mollom VFD on amazon for less than $100. I speculated that it would go up in smoke quickly if it was not up to its specs. But it has been working like a champ for the last year. Maybe I got lucky but the other reviews are good once you discount that there is no manufacturer support.

BTW, the enclosure and peripherals were more expensive than the VFD in the end...

Dependant on the internal condition of the compressor head and the internal condition of the tank, you **may** have scored a decent bargain.

I take it the overall cost is $127.65c ?

Plus tax, so 135 ish.
And riggers fee, probably end up around two bills all in...
