Whats the deal with single vs. dual stage compressors? I've long been thinking that I'd want to get a decent 60 or 80 gallon two stage compressor when I upgrade next. But I was reading the recent TP

Mark if you are going to run a blast cabinet you want all the cfm you can get, but I admit I don't know how to evaluate different rating. And every mfgr seems to use different ratings to make compari

I thought that the point of 2-stage was higher PSI, but that doesn't seem to be the case here. In other words, I bought a single stage IR with a max pressure of 125 PSI, and the 2-stage was rated at

In my opinion it is "the amount of energy you can store in the tank". A single stage will usually have a tank pressure of 125-130 and a dual stage is usually around 175. So you are able to store more

I think you are confusing maximum pressure with the pressure for a rated flow. "19.1 cfm @ 125 psi" does not mean it won't go higher, only that 125 is where they measured the 19.1 cfm. Also note tha

The main thing is that 2-stage compressors are much more efficient at higher pressures than single stage. That means you can store almost twice as much air in the same size tank. No big deal if your

The other side of that is that if you don't regularly need the higher pressure, 2-stage compressors are less efficient than single-stage. You'lll get more air with the same actual horsepower from a s

AGREED, I learned while shopping Craftsman stuff...IGNORE the HP rating, look at the amperage draw of the motor, there is just no way that Craftsman motors can put out 5HP with only 12amp draws, they

The problem is that the rating of the air compressor is in cubic feet _after_ it has been expanded back to atmospheric pressure ... in spite of what it says. Another way to look at it is cubic feet

If that's the rating, then there is no problem. The size of the tank is immaterial (once it's up to pressure) if the free air (SCFM) rating of the tool is less than the free air (SCFM) rating of the

That's not quite right. The die grinder needs its air supply at 90 PSI, but in a minute it will exhaust 4 CFM of free air, not 4 CFM of 90 PSI air or 28 CFM of free air. The drop in pressure across
