Compression - Show Off Your Compressor

[Mr9two9]

I just picked up this, and an oxy actelene setup from a guy on cl. I had to separate the pump from the tank to fit it in the minivan to get it home. It will go under my porch, on hockey pucks /threaded stock drilled into concrete. Also got a funky splitter/ dryer setup. Gonna need you guys help for the wiring, as my box is about full. I thing its setup for 220. Guy had a shop in his garage from previous owner.

Here is my Quincy 310. 60 gal. 1964(date on tank) Bought it from an old gas station. Took it apart and cleaned and painted it. Replaced all the bolts, tubing and wiring. Every where there is metal to metal contact, I have put rubber pads or sheet between. From empty to 140psi takes 12 min. Just wired in the breaker and recp. this past Tues. 06-14-11 . Have yet to run the piping.

Hockey Pucks

Runs so quiet. Sounds like the African Queen.

No compressor to show off, but wanted some opinions. I was in Harbor Freight today and they have these two models:

http://www.harborfreight.com/2-hp-29-gallon-150-psi-air-compressor-68127.html

http://www.harborfreight.com/25-hp-...-cast-iron-vertical-air-compressor-67847.html

I do not have 220 in my garage so that sort of limits me at this point and not in the near future upgrade list.

My needs are to run my impact wrench for the car, truck, trailer wheels, some small tools , etc. Would these suffice for my needs? Anyone own one and how do you feel the quality is for longer term. I know some of the HF stuff can be junk, but then there are the tool boxes that are pretty decent for the money.

Thanks.

I would spend the extra $150 for the 68127. There is a huge difference in these two machines.

The cheaper one (67847) is a direct drive single piston pump so it runs at motor speed. In this case that's 3,400 rpm and 3,400 compression strokes per minute. I expect it's going to sound like a 50cc dirt bike at cruising speed.

The more expensive one is a belt drive two-piston pump that appears to run at about 1/4 motor speed. For the same motor, that's 850 rpm -- but because it's two cylinders, it's still giving you 1,700 compression strokes per minute. It probably gets its higher CFM output from a longer stroke. Expect it to sound more like a lawn mower at idle.

 

[PDACPA]

Thanks Bob. I was leaning to the more expensive one. I just put the two up (I skipped the "oil less" ones as everyone has said steer clear of them) to see what everyone thought. They also have the bigger ones that require 220.

No issue doing what I need though? My little nail gun compressor cannot even tighten a lug nut.

The tools you want to use need PSI rather than CFM. Once your tank is at 150 psi, your impact wrench should work just fine. You will be waiting for the compressor to catch up if you are breaking free all 20 lug nuts in a row.
You will have the same problem as the rest of us. The compressor is handy, the air tools are cheap and you'll find more things that need the compressor. Don't go overboard on this one because you'll want a really nice one when you do upgrade and have the 220 outlet installed (probably the same time you decide to get a welder).

Nice Quincy and Champion.

 

[89GLH]

I do not have 220 in my garage so that sort of limits me at this point and not in the near future upgrade list.

Neither did I, $80 for cable, $5 for a breaker, $8 for a box and an outlet and a few minutes on here doing some research and I was ready to go. Cost me less than $100 to run the cable and add the new breaker. NBD.

 

[PDACPA]

89GLH - you are way braver than me! I will install lights and swap out switches and plugs, but I am a bit out of my league when it comes to the BREAKER BOX! Though seeing how cheap the parts are, I do have a buddy who is a GC so maybe a 6 pack and everything all mounted, he can dig around in my box and make the connection!

Brought this guy home saturday - 1996 SpeedAire 5v401b - it's a 10hp 40cfm 4 cyl 2 stage pump. It was a real too good to be true deal, but I took a risk on it and brought it home.

Alas, pulled it apart and found that someone ran it for a loooong time either full of water or without oil. Spun rod bearings on all 4 rods.

Only put $100 bucks in it, should be able to recoup my loss selling the tank and motor (3 phase, so unless I want use it as the generator in a rotary phase converter, it doesnt do me much good at home...)

Got a good set of heads and lines for the 5v405 pump, if anyone needs them, too.

[bobadame]

Here's my old compressor. Still need to plumb air lines through out the shop.

 

[PsRumors]

Here is mine. It came out of the Coke restoration shop in Atlanta. Haven't been able to find anything about the company so I assume it is either a rebadged pump or chinese knock-off. Either way it does pretty good providing 15.5 CFM at 165 PSI (per my calculations).

And for $500 who can complain.

 

[FlameOut]

My new Quincy 7.5hp. It makes some serious air!

Nice! I wish I had gone with that one. I bought the Quincy model right below that one

If the tank, motor, pressure switch, etc are still good, why not spend a couple hundred on a new pump?

 

[keen]

If the tank, motor, pressure switch, etc are still good, why not spend a couple hundred on a new pump?

for starters - to replace that pump it's more like a few thousand - new it's $2500, lightly used on ebay right now it's $1500. To replace it with a few hundred dollar pump, the 10hp motor would be a bit overkill...

second, the motor is 3 phase - which I can't use.

third, I have a good 140psi vertical tank. I'd like to have a 175 psi tank, but don't have any real desire for a horizontal tank (space, you know...)

pressure switch and check valve I'll be keeping.

What are you going to get rid of/sell? Where are you located?

 

[Neuswede]

Here's my Saylor-Beall when it was set up in my old shop. It's in storage while I build the new garage. It was a 3 phase motor that had been used in a salvage yard in NJ. Brought it home and converted it to single phase and it has been a great tool for the past 5 years. Can't wait to get it moved into the the shop shortly.

Gotcha. Just for arguments sake,

Eaton replacement is 499...

http://cgi.ebay.com/Polar-Air-10-HP...242?pt=LH_DefaultDomain_0&hash=item53e8438f2a

Might be a deal for somebody on here then!

interesting - eaton doesnt list that pump (or any 2 stage pump, actually - they tend to downplay them) on their website (at least not under bare pumps..)

might be a good deal.

 

[bobemmerich]

Man, some of the compressors you guys have are awesome! Unfortunately I can't run 220 to my garage, so I'm stuck with a 115v oil less Craftsman unit. No actual pic, but here is the "newer" model....
http://www.sears.com/shc/s/p_10153_12605_00916472000P?prdNo=1&blockNo=1&blockType=G1#specs

 

[JCQuick]

here's the new one in my garage we got what I think is a smoking good deal.
The ole craftsman 30gal oilless my wife got me 30 years ago it still works but we have projects that require more air. this pic was just after it was wired in

 

[chrommagman]

Hi guys!

I just bough a new used compressor today, it's a speedaire 20 gal
it has duel volt 120 or 220 I have it set up for 120V because my shop is 120V
5.7 CFM @ 90
4.9 @ 135 (max pressure)
the only bad thing is that there was a **** load of water in the tank when I bought it. I think the last owner was a painter because there is some over spay on the motor + pump
here are some pics

the rusty water that came out of it

Mitch and I have been struggling with a lack of sufficient compressed air, especially for sandblasting. Today, we solved that problem when we purchased three compressors out of a powerhouse. These were used for pumping up the air starting reservoirs to start four enormous 16 cylinder stationary Diesels.

Here are a few specs on the new units:

Model: Quincy QR-25 5120
Pressure: up to 250 PSI
Volume: 95 CFM at 175 PSI
Weight: 1,600 lbs each
Power: 25HP

Here's a photo of them:

And a video when we test-ran one of the units:

Now I need to buy the biggest sandblasting gun TP Tools sells. The compressor should cycle nicely while running it. The new Quincy will be able to pump up my current 60-gallon air receiver in about 50 seconds.

I'll be keeping my 3HP IR SS3L for light-duty tasks. Not sure what Mitch has planned for his yet, but I have a feeling it will be interesting!

What can I say? We like big iron! We'll be selling the third unit shortly if anyone is interested.

[1984Datsun]

Here's mine... it still resides on the pallet, and is on the dirt/gravel side of my pole barn. Simple hookups, and when the door is closed between the sides, can't barely hear it running. Go stand by it, damn it's loud... Please excuse my ugly and cheap *** manifold set up... I don't have disposable income like some of you here do.

That will change sometime... I am going to do this...
http://www.dune-buggy.com/webs/Off-Road_Buggies/todd_kirkwood/compressor.html

That will greatly help the severe water problem and possibly some noise. I will add an extended shroud to cover the cylinders completely so air flow is at its best. Also gonna make a bracket for a little squirrel cage blower I got... it's tiny, but moves a **** ton of air. I will have that blow air through the shroud when ever the compressor is switched on.

On the wall in the other side (quiet side...) there is a spot where I ran the 10/2 down so later when I can afford to buy one, I will be able to put a motor starter box in to help the life of the Emerson which some here say is junk... (or whatever motor I have if I have to replace the Emerson before then)

It has no problem keeping up with my air sander. Plenty (11.5 SCFM at 40psi and 10.5 at 90 psi.) Plenty enough for me. For now anyways. I still have the old tank from my old tiny 30 gallon compressor. Thinking about making a bracket, and hanging it on the wall on the quiet side as a reserve tank to reduce the amount of start ups, since I hear the pressure switches on these ain't made for flipping on and off and on...

If I ever wear out that cast iron pump, I'll probably slap a higher end two stage pump on, and slap a good single phase 7.5 hp or so motor on there.

For the price, I say you can't beat this deal if you want to buy new.

Oh, running my IR QTiMax... through 3/8" hose and 1/4" fittings. No problem busting anything loose so far. Will get to try it on a crank bolt soon when I pull the engine from the parts VW... that will test it for sure.

Bet it's time to hook up the big phase converter.

You might like it but if your running them on a single phase non-commercial service your neighbors and the power co are not going to be happy

My 390 @ 20 hp pulls 135amps @500v 3 phase on start up, yours is going to hit 300-350 EASY on start up! I recommend you repower them with a smaller motor and only run them in unloader mode. My power co says max 20hp for my commercial service w/o soft start.

BTW with my VFD I can start and run mine at 2/3 speed on a 20amp breaker! I also have some extra, large Wilkerson coalescing M32 filters and another F35 if your interested

Here's my home set up. I know it's pretty cheap stuff but I got it all for peanuts on Craig's List (Like new 22 gallon compressor $50, Reel 25' for $30.) and it does what I need it to at the house. I have it all set up just how I like it and It's there purely to make life easier.

Thanks!

The trans cooler does sound like the way to go... I was thinking of using the old A/C condenser that I pulled out of my roadworthy VW... but it is corroded and very old... so it probably would just pop if I use it. So then, rather than waste money adapting that cooler on, and then having to redo it all later to put a trans cooler on, I think I'll just go with the latter from the beginning.

One guy (GJ thread IIRC) said he picked up a new in box trans cooler from Autozone for 45 bucks. That's a good starting point for a project like this.

If you use an old trans cooler from a junkyard car or the like, you might want to clean it up real good before using, especially the inside of the cooler.

Again, new probably is a good idea, just because you don't have to spend hours cleaning it up, etc.

Nice. That's a super cheap CL bargain set up if I've ever seen one!!

I need some hose reels... and also to run the PVC air hoses through the hole I made in the wall so I can route them to where I want my drop points to be. I thought of pipe, but it'd be a major PITA to run, be expensive, and having to deal with leaks, etc.

Anyone know if the tank pressure dropping from 135 psi to about 90 overnight is too much loss? It'll hold about 50 psi for a week or so. This is with the ball valve that I have on there shut off. Thinking it might be the gal. pipe from China causing the problem if it isn't supposed to lose that much overnight.

 

[chrommagman]

1984Datsun:

it sounds to me like why your tank is dropping so low it because you don't close the ball valve? but after you are done using your air compressor you should switch it to the "OFF"
