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 happen to own the Champion compressor and its awesome. The thing easily keeps up with my blasting cabinet, comes on for a very short while and shuts back off, very short cycle time while blasting w
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
Oops. Here's a discussion of just such an arrangement, saying it's becoming popular (with much larger compressors than we are discussing) http://www.plantservices.com/articles/2006/278.html Randall _
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
Now what could I add to that ? <G> Things have improved somewhat in that regard, since someone successfully sued for false advertising a few years ago, but I still wouldn't pay any attention to "hors

I need one that goes to eleven! I mean if my compressor is at ten, and my tool is at ten and I need just a bit more.... hmmm, what are they putting in the coffee around here :) _____________________
So in the latest TP tools catalog (who, btw, are local to me...) they show the following compressors that interest me in one way or the other. Champion Centurion $1299 5hp, 2 stage, 175psi max, 19.1

I've always thought it was the same rating method they use for shopvacs - an I.L.S. rating - If Lightning Strikes ... _______________________________________________ Support Team.Net http://www.team.
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
I found this article about electric motor horsepower that answered a lot of my questions. http://www.bacharach-training.com/norm/electric.htm BillG OKC --Original Message-- From: shop-talk-bounces@au
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
HuhHuh... the company I used to work at had a 50HP rotary vane compressor, and a "backup" 25HP. Along with all the CNC equipment, HVAC, etc we typically had $11,000 - $13,000 a month electric bills!
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
