Default Gonna purchase a compressor

So like a lot of people here, my hobby is also my daily driver. I have been slowly going through her from top to bottom. Unfortunate for me, my ambition has gotten ahead of my tools. In other words, I must upgrade the wee little 33 gal compressor. It has done well for me, but it just cant do what I keep asking it to. I would like to be able to do some sand blasting and some small amounts of painting in addition to the regular air tool tasks assosiated with refurbing and older truck.Thats what I'd like to do, but all bow the $$$$$

My questions to you guys are these,

1) what is the main difference in preformance between the single phase and 2 phase?

2) what kind of performance differences do a 60 gal and the 80 gal have?

Thank you for your feadback in advance.

No one has an opinion on air compressors for a shop?

Dual stage will give you the ability to store a higher pressure in the tank, 170 vs 135 of a single stage. Higher pressure is more air stored, and the compressor wouldn't kick in as often as a lower pressure.

If you can, a dual stage, 80 gallon, triple would provide a decent amount of air. I think the best thing to do would be get the equipment you want to run, then buy a compressor to meet those demands.

Thanks. The most demanding thing I have is the sandblaster. 100 lb media blaster. Other than that its just wheels, grinders, and guns (1/2 & 3/8) . I want this to be the last compressor I purchase.

The sandblaster will require a healthy CFM rate, so match your compressor to run it.

I've been leaning towards the 80 gal 2 stage, but the $$$ difference is a huge jump from 60gal to 80, and single to two stage. I guess it's gonna be one of those things where you get what you pay for.

For sure, a significant difference. But, if you do bite the bullet now, you shouldn't have to buy another one again. I have a buddy with an automotive shop that has 2 compressors, each on an OK unit. The total cost for them is more than one really good one that will do the job.

I guess I was waiting for somebody to tell me less is more. I knew that wouldn't happen on here though LOL. It will make life a bunch easier having a good compressor. I just wont be buying that new welder for a little longer now. LOL

Not sure what size tank mine is but I'm guessing its an 80 gallon at least. It is a three phase motor, dual stage compressor, piped throughout my shop at 185 psi. It will keep up for sand blasting but it does run quite a bit when you do. Any other tools are not an issue at all. If you're doing blasting you want the bigger compressor for sure.

I debated the same thing a couple years ago. 60 vs. 80. I ended up getting an 80 gal and I am sure glad I did. The smaller one might be good enough for what you have right now..but remember you never stop buying tools!!!
