Compression - Show Off Your Compressor

[EOC_Jason]

Someone help me. I tried searching for compressors being outside in the cold weather. Looking for AC's that would go inside a shed protected from elements, but not cold NY/LI weather. Most likely not advisable but what the hey.

Any posts/search terms to use to find such topics?

Been tons of posts on the matter... Best advise is to run synthetic compressor oil, that's about all that is required...

Yes im sure there has. Have you tried searching?
LOL... I mean I did but alot has lil mention and most
of the time I get diverted looking at diff garages that
I forget what I was looking for. Besides, it's sometimes
within the topics I mentioned.

I'll have to find some time this weekend.
Thansk!

Found one here: https://www.garagejournal.com/forum/showthread.php?t=379786&highlight=compressor+winter that EocJason mentions

This was in the rafters when my friend bought her garage.

Wow...rivets and a wooden mounting platform.

 

[dkmc]

That's probably one of those tanks that's 1/4 or 5/16" thick.

 

[Trey T]

fixed!

Wow...perfect rivets and a wooden mounting platform.

mechanical/adhesive fastener is still the preferred choice in supercars and airplanes.

 

[redmondjp]

Yeah, the rivets are just fine! It's those two welds on the RH end that are, well, interesting. But at the thickness of that tank, and the low pressure (probably shuts off below 100psi, maybe even at 80), I wouldn't be too worried about it.

It looks like it's been restored! That's a real barn-find compressor, that one is. Complete with vintage warning sign.

picked up an older Devilbiss 5hp, 80 gallon compressor with the 44643 (predecessor to the 247) pump. Gov't surplus auction, came to about 250 after auction fees. Only visible damage is the squirrel cage, looks like it got beat up during a move. I'll clean it up, change the oil and belts, and do any other necessary maintenance, then plumb it in. My shop is slowly coming together.

spent an hour or so with this old Devilbiss Tap-5050 this afternoon. First task is just to clean decades of grease and dirt off it

 

[redmondjp]

WOW did that clean up nice! Excellent job and thanks for sharing the pictures.

I got my new compressor hooked up (finally). It’s a Quincy QT-54. I used a 1/2” hydraulic hose from the compressor to the copper line. Copper tubing is 1/2” Type “L” soldered with silver bearing solder. The regulator is a Parker 06E24B18AC with a Winters PFQ gauge. The compressor is modified with a Square D pressure switch, and a Winters PFQ liquid filled gauge. The power is fed from a 40 amp breaker and #8 wire. The hose reel is a Reelcraft 50’ x 3/8”. I tried to buy “Made in USA where I could. Overall, I’m very pleased with this setup. The biggest issue I had was air leaks from the compressor itself, which were fixed under warranty. Quincy’s choice of pressure switch on this unit is not ideal. It’s really too small to terminate the supply wiring without cramming everything in the housing. Otherwise, it’s an awesome compressor. Well worth the cost.

Can I see a picture of how you have the compressor tied to the copper lines.

Sure-
Nothing too fancy, just a 1/2” hydraulic hose.

Maybe I am missing it, but why is both copper AND black iron being used? Why not just one or the other?

The setup looks very nice. I’ve even saved the photo to mimic stalling my hose reel and ater trap/regulator, just wondering why and how you dealt with the electrolysis from using dissimilar metals issue?

 

[UglySign]

Hey im back.... my QT5 delivers Monday the 9th.

Have a Q because of all the ideas you see during the search while waiting.

This video where the guy puts a Kenworth Air condenser on the wall.
(T2000 condenser, equivalent of Kenworth 486-684-5008)

Is this possible for the QT-5 and has anyone have a setup like so?

Wouldn't it be best that there's less heat esp in the tank?

Is anyone using a high temp & pressure hose from the cylinder head?

Looking to keep things cooler eventually as well as dryer air.

Next Q: Or is it better to just get a refrigerated air dryer and call it George?

Searching is a boon as some of the posts have 20k+ replies.

Thanks

"Next Q: Or is it better to just get a refrigerated air dryer and call it George?"

It is better if you enjoy higher electric bills for no reason. A coil cooler uses little, if any, energy for cooling verses a refrig dryer. Using both will give you super dry air at the least cost. Hayden DB 1260 or 1290 are good cooler to use.
What so terrible about searching for...... compressed air cooler..... or similar words, this has been answered 20k times

Well, looks like I’m going to be picking this beast up. It’s an industrial duplex compressor with twin Quincy 340 pumps and electronic alternator, mounted on a 200ish gallon tank.



I’m either gonna pick up an inverter to use it at my shop, or clean it up and flip it. Not sure which way I’m gonna go, it’s awfully big for my needs. My 80 gallon IR suits me just fine and is a fraction of the size.

Anyone have experience with these big pumps?

Wowee! When you say picking up, what do you have to lift that thing with?

Beast is right, as it weighs probably close to, lessee here (opening up the QR25 brochure), assuming that is a model FF340 with twin 7.5HP motors and a 200 gallon tank, you're at 2250 lbs. (1675 lbs. with 120 gallon tank).

With both pumps spinning, FIFTY-TWO ACFM @ 175psi!!! That will easily run two sandblasting cabinets at the same time.

Nice unit, I would have a hard time parting with that.

Lol, yeah it’s heavy for sure!! That’s sort of the reason for me thinking of flipping it. If I keep it I’d set it at the far end of my storage area and that’s that. I certainly wouldn’t be moving it around!!

Here's my Quincy 240 that I've pieced together from several different sources, I still need to put the motor started together and figure out where I want it as I certainly don't want to move it more than once!

 

[Trey T]

That's a heavy duty single stage beast ... for light duty jobs (home or even auto shop) push it to 120psi @ 900rpm.

Yeah you certainly don't want to move that heavy-*** beast around. How did you managed to get the ~300lbs pump onto the tank?

 

[Bigblockyeti]

With an 80 gallon tank, setting the cutout pressure at 115-125psi should be plenty for what I need to do in my shop. I picked the pump up and set it on the tank platform, it's heavy but I don't think it's 300lbs.

 

[Trey T]

I forgot to mention that all QR-25 single stage pump, except for 210, has a design pressure output limit of 100psi. You should push it to 120psi and it'll be fine

These pump are typically seen in industrial use, such as manufacturing, refinery, or oil field for continuous use (24/7/365days)- the beast of all beast air pump

I did something different with my recently-aquired DeVilbiss 342. I mounted the compressor/motor inside and the tank outside. It is quiet and I actually enjoy hearing it run.

 

[Richard D]

Pictures. I have some somewhere of it finished.

Exactly what I want to do. You in a cold climate?

It’s 80 degrees already so nope!

 

[Richard D]

I cut the mounting plate of the rusted out tank and mounted it in an aluminum frame secured to the wall.

Can you send some of that here? We are all really tired of cold and snow.

Thanks. I used what fittings I had at the time. I’ll change it to all copper sometime soon.

Just picked up my first compressor at an auction this past Saturday! Says it's a 3.5 hp 20 gallon that will do 6.4 cfm at 90 psi. Haven't used it for much other than blowing stuff off and filling tires, but for $130 I was happy.

Changed the oil and cleaned it up a bit since this picture, and fabbed up a hook to mount on my workbench for the air hose.

Possible for the following. QT-54 / 60 gal.
Looking to get a High Temp/Pres SS Braided Hose
made for it. Hose going to Hayden 1260. Im a lil
patinaed going the copper tube method.
Thx

 

[EOC_Jason]

I think 1/2" or maybe 3/8" compression fitting...

What problem are you trying to solve? They use copper tube for a reason- it serves as an aftercooler prior to the air entering the tank.

 

[UglySign]

Thanks Wham, I appreciate your concerns but this is what I'd like to do.
Others have done it, so.....

Yes EOC... 3/8

 

[pcmeiners]

A Hayden 1260 is what you want, just enough fin surface area to cool to near ambient temp, which will drop out a good bit of moisture. As to ss braided hose, I purchased some Teflon lined (1") off Ebay, you will need to locate fittings for it.

Low & behold Moreland Hose is right down the block from my job, who knew. As far as the guy told me, they will have me setup.

Okay, now I get it. I thought you were simply replacing the line because I usually see coolers plumbed in after the tank.
