Good4her,

did you get that 220 line installed?

They never made them in the first place.

That's nearly identical to my DeVilbiss compressor, right down to the belt shroud. Likely the Craftsman was made by DeVilbiss. Doesn't matter though, it's still a very good compressor!

 

[Zrexxer]

Likely the Craftsman was made by DeVilbiss.

No "likely" about it - the pump I had on a Craftsman compressor like that was actually labeled DeVilbiss.

Not technically mine but I assisted my neighbor in getting this 1960's Wayne series 5000 2-stage 175 psi compressor back into operation. It has the original 80 gallon tank with new Baldor 5HP 1725 RPM motor, Siemens mag starter, safety valves, motor sheave/bushing, air cleaner, and pressure switch. This compressor was pulled from a local Firestone Shop in running condition when it closed and sat for 15 years in the corner of his garage. It purrs like a kitten and will probably outlast him!

Brought this guy home a few weekends ago. It's an interesting mix. Basically a Curtis 5E2VT8 clone - a genuine FS Curtis E57 pump, baldor 5hp motor, manchester reciever, assembled in jacksonville florida by Air Compressor Products in 2004.

Works great, a nice 80 gallon 172psi 2 stage 18cfm setup. It'll do 23 with a few more rpm (and maybe a few more hp).

What I haven't entirely figured out is if Curtis had offshored pump production by 2004 or not (or ever? but who can afford not to these days?). Doesn't look like the E57 has changed much over the years, but no clear makers marks that I can find about where it was built. Just the FS triangle logo.

No unloader hooked up, but the valves are there - just have to apply pressure and do the wiring, if I needed to run it that way.

 

[chrommagman]

^ you have a pressure switch right ? they should have a fitting for a unloader valve

 

[keen]

^ you have a pressure switch right ? they should have a fitting for a unloader valve

We're not thinking of the same type of unloader. The unit is setup to depressurize the lines.

I guess more specificly I'm refering to a pilot unloader.

An pilot unloader allows the pump to keep running without producing pressure - allowing for continuous operation without overpressure. Cycling then produces less wear on the motor and pump, and reduces startup power draw.

Not particularly common for most small operations - but pretty common in industrial equipment. And for me, could be useful when sandblasting. We'll see.

I was randomly searching CL and ran across this IR 5hp 14cfm 60gal. It was a thurs night and located about an hour away. I jumped in the truck to go look at it. The owner was asking too much and we settled about $50 apart. My top offer was $250 less than his asking price. I thanked him and left. I was on the road and he called me back saying he talked with his wife and she said he should take my offer. So I went back and picked it up. It came with some rubber isolator foot pads and 50' of hose, not that I needed it, but I'm not gonna complain.
So I got it home and rewired to my needs temporarily till I can get it permanently installed. I also wasn't too fond of the dull grey. So I gave it a nice $5 gloss black paint job. Looks great for whole whopping $5 in rattle can paint I already had on hand. The lift worked great for getting it off the ground to spray the bottom and install a ball valve drain. Oh life is good sometimes.

Nice snag.

 

[Jawn]

I just snagged this compressor on Craigslist for $65. Tank has been repainted, but the gauge says Sears. I'm guessing it's all US made, as the (manifold? the gray part next to the brass coupler) is made by some company in Milwaukee, the motor is marked General Electric (says it's a 1hp, 110v or 220v), and not marked as imported. I didn't notice any meaningful markings on the compressor itself.

Brought it home, checked the oil, tightened the set screw on the motor pulley (it was wobbling and making a horrendous knocking racket) and fired it up.

The good: Runs, pumps up to shut-off at 120psi in a reasonably quick time. Once the pulley was tightened, no odd noises.

The bad: The shut-off valve (red button) leaks, and appears to be one piece with the manifold. The power cord is too small (16AWG, gets kind of warm). And obviously, there is no shield over the belt.

Well post # 175 was at my old house. After moving in (2 + years ago!) I finally took the time to hook up my compressor and plumb a new setup. I decided to bite the bullet and purchase some 3/4" "L" copper and follow some advise and setups I have seen here. I have not used it other than testing for leaks and blowing out the garage, but I have not seen much moisture, even though it has been pretty humid.

I decided to run a radiator type setup rather than pipe around the garage. I plan on building a workshop eventually and this setup would be easy to move and adapt to the new location. I placed it behind the compressor, thinking the fan will facilitate with cooling the air. There is 30' total of piping before the filter.

Had one and it sucked big time, would not even run my 1/2 IR impact,

not a great air compressor for the money..... think it was made by DeVilbiss for sears if your using it put a auto drain on it it makes a ton of water when it runs

 

[jtbinvalrico]

Husky I picked up off CL for $300. My old regulator setup was trashed so I picked up a new one and the filter. The 90* exit saves some wall space for more toolery. Replaced the stock drain with this easy-to-use setup. Finally, I used the hockey puck idea I picked up from you guys to make these adjustable feet.

 

[GTOGreg]

Finally, I used the hockey puck idea I picked up from you guys to make these adjustable feet.

I used that idea too...works great, and can't beat it at $1/ea most places. Just make sure you don't tighten the nuts all the way down tight. You want to leave just a bit of clearance so it doesn't stress the joints on the compressor feet.

I guess now that I've posted on this thread I owe a pic of my own setup...

This install is under a "porch" outside of the shop. I will be enclosing it with walls before winter and adding heat trace to prevent freezing. The original outlet from the factory tank only had a 1/2" valve, so I removed and added a 3/4" valve and piping into the shop.

After the pipe enters the shop, it T's. One outlet is currently used, and the other is for a future drop. After the 3/4" T, I chose to use 1/2" stainless steel tubing and Parker fittings. The PSI rating for this is well above 1000 psi, so it is safe. The reason I chose this is I had access to used fittings so my cost was only for the ferruls and tubing.

The regulator & filter is mounted under my loft as close as possible to the hose real. When the next drop is added, there will be a second regulator & filter.

The compressor is set to turn on at 150 psi, and the air regulator is adjusted to the recomended 90 psi max for my air tools. Why leave my compressor at 150 psi? The higher the pressure... the less pressure drop across an orifice (ie pipe).

There have been no issues operating any of my air tools at 90 psi with this system... it works great! I have also been very pleased with the moisture that falls out into the water trap... and have had no water collect into the bowl of the regulator. This tells me that all of the water is condensing out before entering into the regulator.

I also purchased rubber feet from McMaster-Carr for the compressor... they seem to dampen the vibration very well.

Here is mine, after years of great service and hour after hour of pumping 50% air and 50% water in this Florida humidity, I finally upgraded from my Home Depot special 50 Gallon, to this nice Curtis. The real nice addition is the refrigerated cooler. If you live in Florida, you can't live without it.
I justified it this way. When I paint a car project, I spend $1,500-4,000 just in paint and materials. If I screw it up, I am out a big chunk of that money.
That plus the benefit of clean dry air through the plasma cutter, and there is no other way.
I also splurged on the auto-drain and have never looked back. I am set for the next 10-20 years!

Here's one I'm building. 308 Quincy. I had gotten the compressor from my dad that he had rebuilt who knows when. It was never used since. I just fired it up and it's not building oil pressure. I guess something is stuck from storage. Anyone has any knowledge on these before I start investigating?

Thanks.

 

[A_Pmech]

I just fired it up and it's not building oil pressure. I guess something is stuck from storage. Anyone has any knowledge on these before I start investigating?

1) Does it have sufficient oil?

2) What direction is it rotating? When standing on the flywheel side and looking at the flywheel, standard rotation is counter-clockwise.

3) If it has been in storage a long time, consider priming the oil pump though the oil pressure gauge port. If the oil pump is entirely dry it will not develop sufficient suction to pull lubricating oil from the sump.

4) After priming the oil pump check and adjust the oil pressure relief valve adjusting screw directly left of the oil pressure gauge.

Whatever you do, be careful running the compressor without oil pressure. It doesn't take much dry running to destroy journal bearing inserts.

Thanks for the reply. It was the sleeve around the vane rotor that was stuck. I got oil pressure now.

 

[2manytoyz]

Jeez, some of ya have MONSTER compressors!

Nothing fancy in my shop.

Nice that the storage tanks can be removed for easier transport.

I also modified a Q89 12V (45A) air compressor with an external tank & pressure switch, and put it into the back of my truck. Now it will support limited air tool use, filling tires, and blowing the sand out of the bed of my truck.

CH 60 gallon, 5 hp, 220v.
Price ........ FREE!!!!
Buddy who runs a rental shop had this "die" on him one night. I got it mainly for the air storage to plumb into my existing compressor (crapsman 33 gall upright). Well after checking it out I found an O ring had broken in the pump head. Found the rebuild gasket kit and ....... $26 bucks later she runs!!!!
Had it for 6yrs now and still counting.

I used a MAXair 60 gallon in my shop for awhile, then picked up a larger Champion 10hp unit to better run my cabinet blaster. Got it used from a VO-Tech for $300 and it has been going strong for 3 years.

 

[47p2]

My kind of thread, some superb compressors here.

I have 3 compressors at the moment, the first is a single phase (240v in the UK) 2 hp which I bought many years ago, it's adequate for blowing up tyres and running some smaller tools and that's about it.

This is a 3 phase (415V in the UK) 1968 Ingersoll Rand. Almost silent but just not enough puff for the larger tools

This is the daddy compressor. It's a Hydrovane screw compressor with an output of 23CFM and more than adequate for my needs. It doesn't require an air tank as I have no tools that can outrun this beast.

I also have an airdryer, but only use it if I'm spraying

That is amazing that this works with out an air tank? So does it ever go down in Pressure? I have just never seen anything like that

 

[petee_c]

I got this Champion, "Porta Champ" 20 gallon oil lubed compressor used on kijiji for $140, with the hose and blow gun back in April. Runs well, 10x quieter than the Campbell Hausfield 13 gallon one it replaced. I sold the CH one for $120 to bro-in-law.

Someday, I'd like to piggyback a 10gallon storage tank to it for slightly more capacity, I run mainly a impact gun with it, sometimes the air ratchet. Also use it to power a variety of nailers.

Not with any tools I have, the first picture is it running without any tools

This paint dryer was connect to the compressor and uses 15 CFM

and it only dropped a couple of pounds

 

[kams1973]

Here's my latest air compressor build. It's a 2 stage, 3hp, United States Air Compressor Company air compressor saved from the junk pile. The tank was also a USACC saved from a different junk pile. It's not 100% complete, but close enough for pics.

 

[NewShockerGuy]

You can do that! here is a tip that I found out. Put the teflon tape on then put some disk brake quite on the fittings, wait till it's tacky (almost set) then put the fittings together. It works very well because that disk brake quite forms a silicone seal.

With this leak have you tried soapy water in a spray bottle??

I can't stand using teflon tape... I use loctite for all my fittings. Ever since paintball and messing with the tape I could stand it...lol Loctite to me has never let me down, especially when it came down to fittings and a 4500psi air tank.. I always use blue threadlocker. And used it on all the fittings for my air compressor/hoses/reel.

I will have to post pictures up later today of my air compressor.

[70chevellegsp]

I found mine in an old guys yard in a residential part of town. He used to own a bodyshop and was selling it. It's an 80 gallon Speedaire with a Champion R15B pump and 5 hp GE motor. I got it for $275. I'm going to need a new tank at some point in time, but it works very well and I can rebuild the pump when needed for about $125. I plumbed the compressor in with 3/4" copper with 3 drops.

 

[phiftyseven]

Nice compressor and piping job. What caught my eye however was the garage door springs. They look pretty scary to me. I'd replace them as soon as possible. Also add a couple of safety cables inside the springs. I'd be affraid to work in that garage with springs looking like that.

Here's my 57 DeVilbiss that came with a house I bought back in the 90s. Owner decided it was cheaper to buy a new one than it was worth to move that one. I'm glad he took the lazy man's route. I don't use it a lot, and it gets awful noisy pumping when it gets above 120 PSI but other than that she's still going strong.
