So, I'm starting to get into gear-acqusition-mode (which can only be cured by purchasing item in question) on an Air Compressor for the garage. I've done work on all of my cars and boats for years without an air compressor. I'm ready for an impact wrench and all the other goodies that come with 90PSI worth of air. I don't see myself using high-CFM tools like sanders and paint guns. Mainly air rachets, impact wrench, etc.
What I'm finding is that it's tough to find a compressor with the following attributes, roughly: - Oiled (not oil-less) - Belt Driven (I don't know why in particular- cool factor?) - 20-30 Gal - Under 300 bucks - Vertical if possible I don't need/want some huge 90 gallon professional compressor, but a the same time I don't want a cheapie noisy oilless consumer model either. I want the sweet spot inbetween. There are not many choices in this particular space. Harbor Freight has the cheapest compressor that meets the majority of the requirements that I've set: http://www.harborfreight.com/air-tools/oil-compressors/35-hp-25-gallon-125-psi-air-compressor-99925.html - HF 25 Gal Oiled Direct Drive Vert With a 20% off coupon that compressor would go out the door at less than 200 bucks which is completely insane. Checked this one out in person and it looked OK but I went in with the intent to buy and walked out after I saw it in person. That said I'd reconsider if there is no reasonable alternative. Menards has a horizontal twin-cyl belt drive 30 gal for 369.00. That's a little more than I wanted to spend, but I have my eye on it. Lowes seems to only have consumer oil-less or pro giant compressors. Haven't checked Home Depot recently, nor Sears. Thoughts? Ideas? Input? ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

Joel,
The biggest spec you need to look at when looking at one of theses cheaper compressors is the CFM rating. Do not go by the HP BS. That is peak locked rotor HP and not a true running HP. It's a marketing scam that you find all over now especially at the home centers. Looking at the CFM, that 3.5 "HP" at Harbor is really only between a true 3/4 and 1 HP. Figure out the CFM you need for the tools you want to run and go from ther. You also need to consider a duty cycle. These less expensive compressor are not meant to run 100% of the time unless you want a very shot life span. Unfortunatly, you don't find a duty cycle listed on many of these cheaper compressors. This in one item that really fits into the catagory of "you get what you pay for it". ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Not a bad choice but here's the other problem you may run into. Joel, what power do you have in your garage? The above is a true 2 HP needing a 50 amp circuit at 120 volt or a 25 at 240 volts. 240 in the garage? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I second the idea of Craigslist or Ebay, a good brand used is better than an El Cheapo from Harbor Freight or similar.
There are a ton of compressors sold out of defunct machine shops and other plants, but hard to find the smaller ones, most will be higher power, bigger tanks. But, you never know, so might be interesting to search for auctions or liquidation sales in your area. Like Pete said, figure out the cfm you need and go from there. I've got a few 20 HP 3 phase if you're interested, you could supply air to the whole neighborhood with one of those! ------------- '63 American Skier - '98 Sport Nautique |

I feel your pain Joel. It's hard because my natural instict is to buy really nice tools/equipment that'll last. But trying to balance that with the "weekend warrior" frequency of use, and not wanting to spend a fortune on things that won't see daily use.
I agree with Pete, you typically get what you pay for. But I couldn't justify a super nice compressor. I went with a 240V 60 gal. with a little over 10cfm @90psi, all cast iron. I don't like the 60 gal. tank size, but I had plenty of room so it's not a big deal. It lists for $450, but they were having a sale one weekend...got it for $400 & got a $50 rebate, so $350. It's still overkill for what I'll use it for. http://www.tractorsupply.com/tools/air-compressors-air-tools-accessories/air-compressors/campbell-hausfeld-reg-60-gallon-cast-iron-air-compressor-3310006 - compressor ------------- Craig 67 SN 73 SN http://www.correctcraftfan.com/diaries/details.asp?ID=6103" rel="nofollow - 99 Sport 85SN |

When I lived in Orlando I bought a 3-hp Gas powered air compressor it has a 30gal tank on it. It was a great investment and being gas powered I could utilize it anywhere. I rebuilt a couple of jumps it came in handy when we changed out my brothers motor in his truck. getting a electric compressor kinda limits you to an outlet where gas lets you utilize it anywhere. Mine is now mounted on a flatbed trailer along with a welder that my brother in law and I share from time to time. ------------- Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise. 1993 Shamrock "fat" 20. 2008 Nautique 196 5.0 |

Not given, You must need plenty of air! What are you into that you need that much? You've never told us. The IR compressor isn't one of the real cheap poor quality compressors but it certainly isn't a very good one ether. Although cast iron, it is a Chinese import without many of the features needed to make it a high quality compressor. IR like so many of the old line US companies have fallen into having their products made over seas and then sticking their name on them. They are running on there name and mass marketing. You are lucky to have the power to run a 10 HP. Most here including some commercial members do not even have the 3 phase needed to run 10 HP. Yes, 10 HP single phase motors are available but over 7.5 HP are rare and expensive plus need a dedicated 90 amp 240 line. The single to 3 phase converter I pictured above is a alternate but at 10 HP converter costs as much as the IR compressor!!!! The converter is a "no other choice" method of having to run a 3 phase motor without having a 3 phase service. If you do need that much air, your choice of compressor type is a poor one. Anything over and including 7.5 HP it's best to invest in a rotary screw.
Now, with that IR recip, you will need to purchase 2 or 3 times!! Sounds like you shop for compressors the same way you do for oil and filters!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Joel, for the money you're looking to spend anything you buy will be in the same league quality wise. For the amount of hours you will put on it all you need to do is keep the oil level full, change the air cleaner regularly and oil your tools. If you keep a reciprocating compressor oiled it will run for years.
I have a not very expensive Campbell Hausfeld 7.5 hp 2 cylinder single stage at the shop that I've been running since 1996 8 hours a day 5 days a week at a 50/50 duty cycle. I've replaced the valve plate 3 times but that and regular oil changes and it won't die. ------------- You can’t change the wind but you can adjust your sails |

Alan, I'm thinking the same thing. I'm leaning more and more toward the HF unit. Apparently a lot of that US General stuff is manufactured by the same factories that manufacture other brands (they just slap different labels on them), and I could buy 2 of them for the price of most other compressors in that league. It's also the ONLY oiled unit even remotely in that price range and that configuration that I've been able to find. Typically at around 200 bucks you'd be looking at a PowerMate oil-less. ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

Pete, I don't agree on your screw compressor comment. Rotary screws are definitely the way to go if you use a lot of air, a lot of the time. If you use a lot of air, some of the time I'd still go with a recip, and if you go with a recip and a large tank you reduce the number of cycles.
I'm reading with interest as I need a little compressor for home use. At the lake I have a little Craftsman compressor, not even their better green line, one of the cheap red ones. It has been fine for around 10 years now, but gets only a few hours use a season. For home I'd like something a bit larger, a bit quieter, a bit better quality. I get all the Harbor Freight ads, have been tempted to go with one, but decided to look for something used and better. I do have a Harbor Freight charger/starter that has worked great, it's built really cheaply but I'm careful with it and it has done the job. ------------- '63 American Skier - '98 Sport Nautique |

David, You are correct that it all comes down to the air required and proper sizing of a compressor for it's duty cycle. However, I'll stick to my comment on going rotary with anything over 7.5 HP. I manage a maintenace crew that takes care of 10 compressors totaling close to 800 HP. We've been through a few recips but not one screw in the past 21 years! But, for the home garage shop no!! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I defer to your opinion, sounds like you have a ton of experience with both! We're running a 10 HP recip to death, mostly because it's in place and we have so many other projects we can't think about it right now. When we need more air, only a few hours here and there during the week, we kick on a 40 HP screw, it's got to be 40 years old and still runs strong. I've got an old Gardner-Denver horizontal recip, I believe 40 HP, that we ran until the mid '90's, it only needs a valve job and would still run today. What a neat machine, quiet as can be, just a low pitched thump-thump-thump and made a ton of air, but only good for about 90 psi. ------------- '63 American Skier - '98 Sport Nautique |

Joel, everything you compare is a trade off, remember that cfm is rated at differnt pressures, make sure you are comparing aplles to apples.I would agree with getting an oiled compressor for longevity, so long as you will never run it outside below zero, I would take the time to consider everything you might wish to do with it, you will likely never NEED to buy another one in your lifetime. Will you ever want to take it to a family members house and run roofing nailers? Will you someday want to run sanders or buffers off it. For occasional air ratchet use a ten gallon with high cfm might be enough, It takes 15 amp power and you could still take it somewhere, but if you want to buff out a boat it would be undersized. I have a little makita, maybe two gallons that I use for flooring nailers, it is oil filled and has outlasted any oiless I have ever owned (5 I believe, I used to go through them every 12 to 18 months.) It will run three flooring nailers all day long but empties quikly with an air ratchet (it will get a tire off my truck, just have to wait to refill between lugs). The cool part is it has a large pump geared down so it refills quikly and is quite. It can be run in the garage at 10 pm without police visits. It sold for about 200$ new, and they put the same pump on larger wheeled tanks. I also have a little $69 husky in the garage for filling bike tires. It has about a half gallon tank but it is the one I pulled into the basemnet when I re-upholsterd the boat. You will enjoy having one around, it is easy to find uses once you have it. I cannot imagine life without one. ------------- For thousands of years men have felt the irresistible urge to go to sea, and many of them died.

I bought a Craftsman compressor off Craigslist today, was a few miles across town so very convenient. An older woman whose husband was now sick was selling it, very pleasant and a good transaction all around. I paid $120 for it, seems to be in very good condition, not used much and manual came with it.

Just to wrap this up- purchased a compressor, finally. Had a bunch of Home Depot gift certificates burning a hole in my pocket so I went with their Husky Pro 30 Gal, belt driven, single phase, oiled 2-cyl compressor. 379.00. Not bad at all. It's actually a CH unit, and I can even see the shipping label saying it came right from CH! It's insanely heavy and came bolted onto a pallet. It had to be taken with a forklift to my truck, into which it just barely fit amidst jeers and side bets from HD employees. It can be wired for two-phase, which is probably what I'll do down the line. It's quiet, it doesn't pop the 20A breaker (although I get a satisfying dim of the lights when it kicks on), and I pretty much like everything about it so far. Just broke her in and changed the oil for the first time. Thanks for the help guys. I'm finally air-powered.

I have a Airmate by Emglo 230V 3hp direct drive with oil. I think it has a 30 gal tank and has served me well for about 25 years. I believe the electrician used two spots on the fuesbox to get the 230. It has a twistlock three prong. I bought it from an Auto Body supply shop. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=4487" rel="nofollow - 1998 Ski Nautique |

Joel, I think you have the rough idea but bad terminolgy. Altough "two phase" was used many years back in some rural areas, What you really mean is the unit can be wired 240 volt which uses both hot legs of the power coming into the house. It's still single phase. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

No, still single phase. 1 leg and neutral for 120, 2 legs and neutral for 240. 3 phase has 3 live leads in the service, 4th lead is ground for safety, actually not a part of the power circuit.
This explanation is from a non-electrician, so I apologize if any terminology is wrong, but I think the jist of it is right. My understanding is that the 2 live leads in a single phase service are in same phase, but not sure of that. ------------- '63 American Skier - '98 Sport Nautique |

63, that sounds about right. I was figuring any multi-leg input would work like a 3-phase motor, using the offset of each phase to it's advantage. It would make sense that the residential single phase legs would be in sync. ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

I don't understand the phase thing either,but my Dad had 3 phase in his business 60 years ago.It was a different because back then it was pretty rural where he had it.I guess the advantage was you used less electric on big motors. I think Joel the same would be true on your compressor too,220 over 110 would use less electric, but you might not notice the difference on your usage tho. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

you probably want to hook it up to 240 initially, easier on the pocketbook when the electric bill comes, I dropped a 240 line right under my fuse box in the garage to run the compressor ------------- "the things you own will start to own you" |

No. Go take a look outside on the utility pole. You'll have one transformer being feed from one primary. That primary is only one of the 3 phase oscillations. The transformer can not change that wave form. For 3 phase, you need to use all three primary lines on top of the pole. The 3 phase comes all the way from the generation source! FYI, the "neutral" coming into the service entrance, is the center tap off the secondary winding of the transformer. Half way in the winding is what gives you the 120 volts off a 240 transformer. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Ever have one of those useless conversations at coffee break that just pass the time? We had one on your 50/50 comment. Our electrician said it can't be 50/50, he hooks up 3 leads but each lead isn't 50/50 since it depends on the others, he said he has a 2/3 chance of getting it right. I said no way, it's a true 50/50. I don't have a clue who is right! Over the years watching countless machines hooked up it seems 50/50 to me. ------------- '63 American Skier - '98 Sport Nautique |

David, It's a 50-50 chance since you only need to swap any two of the 3 phase legs. Hook up first time - wrong direction - swap any two legs - correct direction! That in my mind is a 50-50 chance. Ask your electrician if he's ever had to swap legs 3 times to get it correct! If he has, he must not be keeping track of his connections! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

The CH guy (who has been very helpful) said the safety valves are set to 150PSI. My pressure switch is stopping the pump at about 135 PSI (normal) and that's pretty much exactly when the safety valve is popping off. They're going to send me a new SV first, we'll see how that goes. ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

Here is one everyone should stash into memory.
P = I x V P=Power (watts) I=Current (amps) V=Voltage (Volts) An electric company charges you for watts over time (kW-hr). Like Pete said, changing the wiring of your motor to 240V will decrease the amps it will draw, but will not affect the power. ------------- Craig 67 SN 73 SN http://www.correctcraftfan.com/diaries/details.asp?ID=6103" rel="nofollow - 99 Sport 85SN |

Halston,
The IR isn't bad for your planed usage as long as you size it large enough so the largest air load doesn't run it past it's duty cycle. Up from IR would be a Quincy and then top of the line of recip's I'd go with a http://www.fscurtis.com/ - Curtis . ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

You need the cfm to run the air tools, but also a compressor that will hold 120 psi plus for the impact wrench without dropping. The largest 110 volt compressors will be OK, if you can go up to a 2 stage 220 volt you'll never run out.
My little Sears that I bought on CL has been great, though I haven't tried an impact wrench with it, my guess is it would be fine in short bursts but would drop if I had much steady use. ------------- '63 American Skier - '98 Sport Nautique |

I'd have to agree here. I'm looking for a compressor for my home garage to run sanders,etc. I've been told to take the highest cfm consuming tool you intent to run and double it since the duty cycle of a recip compressor is 50%. That puts a 6 cfm air file needing a 12 cfm @90 psi air compressor. I can not find that at 110 volts. I was handed a 5hp 240v compressor last week for the cost of a new pressure switch. It will get me 9.3cfm @ 90 psi, not really enough but it may get me by until the right one comes along. Need to wire the garage now so we'll plan for the future plus put in a hookup for a larger welder too.  ------------- You can’t change the wind but you can adjust your sails |

I bought the IR SS5L5 compressor about 4 years ago and it was trouble free until the motor exploded back in January. I checked online and found it was a common problem and the motor had been changed on later models. Called IR not really expecting them to do much, got right through to customer service and 3 days later I had a brand new motor sitting on my shop floor free of charge.
For a one man shop this compressor does fine. Plenty of cfm for sandblasters, both cabinet and pressure tank, HVLP spray guns and air tools. |

I have seen these at Tractor Supply. They seem like nice compressors, However i am only 23 and want to buy something that will last me a long time. I am wondering Pete if a 7.5hp or should i say 23.5 cfm 80 gallon compressor is enough in the Curtis brand and what is the cost on one i cannot find a price online. You would say that http://us.fscurtis.com/products/?id=45 - CURTIS is top of the line ?  ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=5528&sort=&pagenum=1" rel="nofollow - 76 Nautique "If you do what you always did,You'll get what you always got!"

Just to follow up here- my
Has been working great so far. I've run tons of different tools on it, but nothing crazily air consuming like a DA. Seems to charge up pretty quickly and it's one hell of a chunk of machinery to run on 110. My garage is on a 15A breaker and I can run all my shop lighting, radio, trouble light, etc. along with the compressor with no problems. Love that. ------------- 2000 SN GT40 w/99 Graphics/Gel 2016 SN 200 OB 5.3L DI https://forum.fifteenoff.com |

Halston,
If you are looking to spend a couple grand Air Compressors Direct has a http://www.aircompressorsdirect.com/FS-Curtis-775VT8-Air-Compressor/p4462.html - 7.5 HP Curtis for about $2200. For comparison purposes I love my 93 vintage http://www.drillspot.com/products/35819/speedaire_4xa59_stationary_air_compressor?s=1 - Speedaire it makes short work of any sanding, painting or cabinet sand blasting I have thrown at it.. a very luxurious compressor for a home shop. I previously used the largest 115V unit I could find and even at a little over 15amps you would never want to run a sander or even a decent right angle die grinder with it. I am sure there are great compressors between those two sizes as well. I am sure that the curtis unit would be spectacular and Air compressors direct does seem to have some great pricing. Of course I am cheap and picked mine up for about $300 on craigslist. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

Halston, Unless you plan on doing alot of painting, then a refrig drier is really more than you need. Most of the better recip's are offered with aftercoolers and auto tank drains. It's really a simpler way to go. Then, if you do want to do some smaler paint jobs, get a coalescing filter on the line. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
