$200ish for a new air compressor?

Can it be done without buying a POS?


I have a 10 year old oilless devilbilss compressor, and it's getting louder and taking longer to fill. Just put a new pressure switch in it, and that helped (old one leaking)

It still just doesnt cut it. 3.5hp, 20 gallon. Run an impact wrench for a few bursts then needs a 5 min recharge if you need any force out of it.

I want something quietish, and able to keep up. I'm guessing that puts me at a cast iron oiled unit, but even the harbor freight ones are $250+

Should I just bite it and buy a decent one?

Those small ones dont have enough capacity to do much more than air up tires, if you use real air tools - you would be better off getting a real piece of equipment, i tried the lowes equivelent and had to take it back, it couldn't cut it.

Another option is an older used compressor. I saw one at auction last Saturday that was made specifically for service stations, by Service Station Equipment IIRC. I don't know what it sold for, but it was represented as in working condition. It was built to last a lifetime. I have for my own use a 1967 John Wood with a Westinghouse pump on it, it already has lasted a lifetime and looks like it could go for a second. It's also relatively quiet.

Basically, yes. It's a tool that you will have for a long time. Buy a good one.

I would look for a small used unit. About 10 yeas ago, I bought a 12 gallon Sanborn Magna Force for $75.

It's a low RPM belt drive model that's pretty quiet and it also has enough capacity that I was even able to paint a car with it.

I picked up one of the 4 gallon oil-lube 2 1/4 HP units at harbor freight and it makes a ton of air....I can run my impact for close to a minute before it can't keep up, then it only takes about 30-40 seconds for it to fill/click off again....for the $90 I paid....its a beast, I've used it a ton so far.

On Air Compressors, bigger is always better. Both in terms of longevity and usefulness. Having said that, budgets do not always allow for the best tools at a given time.
Forget all about HP ratings. The only thing that matters is air delivery at pressure. Compare air delivery at the pressure that is closest to what you will require, and buy the most that your budget permits. You can always upgrade later.
