It won"t check out a ton of usage, just periodically as soon as I require it to inflate a tire, blow off sawdust or dry a component, or carry out some airbrushing, so I"m thinking a 5+ gallon tank and also 1 HP or so. My 30+ year old Speedaire tank is losing air, more than likely a rusted-thru pinhole somewright here, and it"s time to replace it.

Mine has been working fine for around 3 yrs. I use mostly to shoot nails, but also usage for cleaning, pumping car tires, and so on Even sprayed paint. it kicks on more than I would like and also it"s not going to win any awards for quietness, yet it works for the handfull of times I use it annually.

I had 1. I sold it once. I uncovered a bigger Craftsguy at a garage sale. My first one went back. The manager told me no one puts sufficient oil in them and the directions are negative. He said fillit till it starts to run back out the hole. It functioned fine as line as I had it after that.

That shelp I bet you have the right to discover a far better deal on a provided compressor on fb marketplace

I’m buying a new compressor quickly as well. I want to have the ability to spray clearcoat and use air tools, so I’m gaining a large 220v dual stage of some kind. Basically “shop air”.

Check out https://www.aircompressorsdirect.com if you haven’t yet.

I have a small porter cable pancake compressor that I’ve offered the hell out of for the last ten years. I usage it to shoot nails, inflate tires, blow gun, and so on it’s excellent because it’s basic to lug about.

Harbor freight is excellent for some things however I’ve had trouble through tools. Just shed out a 2nd hammer drill. Won’t buy an additional from them. Haven’t been brave enough to attempt their compressors.

Well, whatever brand you go through (especially at HF) it the majority of most likely won’t be built as well as your Speedaire. I think you’d be better off trying to discover out where the leak is coming from and also seeing if it’s repairable. You sounded like you weren’t certain. They just don’t develop em like they they offered to...

If the tank has a pinhole leak, then it is a ticking time bomb and should be replaced. If you have ever before checked out one let go in a shop, you will certainly understand why I say that. Not worth the few bucks you would be saving.

Yeah, I sat on a product licapability jury for a big commercial compressor manufacturer. A manifold (basically, a 3" lengthy L-shaped exhaust pipe) that flew off of a compressor under test. It flew 30 feet through the air and also hit a man in the head.


I usage mine for minor points. The rare instance when I had actually it associated to a nail gun, but mostly for inflating tires, and the occasional blower nozzle. It"s loud, but it functions. The ground prong damaged off of mine, have actually yet to relocation the cord as I"m also lazy...I have the 8 gal tank, bought it with sale/coupon for less then $100 IIRC numerous years earlier.

I"ve heard The golden state Air provides a nice quiet small compressor. I"d most likely obtain one of those if I ever need to replace mine.


I have actually a 21 gallon Central Pneumatic compressor (actually on my second one). If you"re going to buy it and use it, make sure you get the 3 year plan. The motor is super loud, runs a lot and also doesn"t last too lengthy. I flipped my house I am in, so did interior and also exterior stuff (both spraying paint and nails/brads of all sizes). The motor will speak functioning and you need to recollection or save jostling the switch on and also off to make it work-related. Once you know the nuances its not also poor.

By no indicates the best compressor, however if you understand what your gaining, its tough to beat the price.


Find an old craftsman digital that has an actual piston for pumping press rather of those new cheap vibrators. I have been using mine for heavy stuff for over 40 years.

It hasn’t been identified that it’s in the tank though. I had actually a leak on my 35 y/o compressor and turned out it was a fitting on the hose that was leaking progressively. Just saying it’s worth a shot to investigate. But I agree that if it’s the tank, then don’t try to repair. Should have actually been even more clear in my initially short article.

EDIT: I guess that’s why I shelp “if it’s repairable” earlier.


They last a pair years however are certain noisy. I’d like to pay a little bit more and also acquire one that’s quiet. Any suggestions?


Quoted from Electrocute:

They last a couple years but are sure noisy. I’d choose to pay a little even more and also acquire one that’s quiet. Any suggestions?


Never before get a Harbor Freight straight drive. They are loud. Belt drive for quiet operation. Also, avoid "oilless" compressors as they are loud.

Campbell-Hausfeld FTW. They currently sell straight drives that are supposedly quiet. Try prior to you buy.


Quoted from Pinzap:

It hasn’t been figured out that it’s in the tank though. I had a leak on my 35 y/o compressor and also turned out it was a fitting on the hose that was leaking slowly. Just saying it’s worth a swarm to investigate. But I agree that if it’s the tank, then don’t try to repair. Should have actually been even more clear in my initially article.EDIT: I guess that’s why I shelp “if it’s repairable” earlier.


I just checked it out a tiny closer. I kbrand-new the leak was coming from approximately the moisture drainpipe valve, so I filled the tank and also sprayed some water on it yet didn"t watch any fizzing. Then I sprayed it into the hollow of the threaded component of the valve that transforms to open it, and might hear a fizzing noise from inside. So, I"m guessing it just needs to have the valve replaced? The rest of the tank is solid, so apparently there"s no genuine require for a new one with the infrequency that I usage it.


They are garbage, don"t bvarious other. I made the mistake of buying one. The damn point wouldn"t fill the tank. Took it back.


Ridiculously loud, yet I’ve had actually mine prob 10 yrs. I put actual compressor oil in it, forgot which brand yet it was USA made. Which is prob why it still runs. The crap they sell tbelow is water. I have the 21 gal 2.5hp model


Hft compressors arent a lot, cant also obtain extended warranty. Buy a compressor through oil in motor, oiless compressors are a lot louder, I hsvent had a lot luck with craftsman, huskies from home depot ok


Quoted from atum:

The motor will certainly sheight working and you need to reset or save jostling the switch on and off to make it work. Once you recognize the nuances its not too negative.


This typically happens when you have an undersized circuit or expansion cord. Make certain any kind of extension cords you usage are of the correct rating and you will not have a trouble.


HF is excellent from some thing prefer bar clamps, spring clamps, c clamps and devices that have extremely few moving parts, I"m a firm believer before in one gets what one pays for, learned the difficult method through automobile components from rockauto. Nothing like doing the exact same task twice in rapid succession, it"s twice the price and also as half as a lot fun!

I"ve obtained one. I mostly supplied it once I had a sandblasting cabinet. It functions fine, however it"s noisy and produces a LOT of water. If you arrangement to use it for sandblasting or paint, you"ll have to connect a pair of driers inline to sop up all that water so you obtain clean, dry air. Without a doubt not somepoint I"d select if there was any type of volume or consistent usage involved.


Quoted from Atari_Daze:

HF is excellent from some thing prefer bar clamps, spring clamps, c clamps and also devices that have incredibly few relocating components, I"m a firm believer in one gets what one pays for, learned the difficult method with vehicle components from rockauto. Nopoint choose doing the exact same job twice in quick succession, it"s twice the price and as fifty percent as a lot fun!


Replaced the draincock (heh heh heh!) this afternoon and also no more leaking. The motor is still noisy, but I love a $5 deal with so a lot more than a $100 resolve.
