Friends,


I'm new to pneumatic tools. I'd like to get an impact wrench and ratchet to add to tools.


Right now, I have a small compressor (Hitachi 2hp/4.0 CFM at 90 PSI). I use this for inflating tires, blowing off parts, etc.


Many of the air tools I've looked at require 4.0 or more CFM to operate. Here are my questions:


1) If I shop for an impact wrench and an air rachet that require 4.0 or less, will I be okay, or is this not something you want to cut close. Should I be running a compressor that far exceeds the requirements of my tools?


2) If I need a beefier compressor, what specs should I be looking for--how many CFM, gallons of capacity, one-stage versus two stage, etc.?


3) This won't be something I use everyday--just for maintenance on my rig and some light duty work on my quad/dirt-bike. I know Ingersoll Rand is a big name in this space, but would I be just as well off saving the money and getting a Craftsman? How imporant is name-brand in this area?


Thanks,


Terel

terel,


Most air tools that are capable of bigger torque numbers required for larger fasteners start in the 6cfm range. If your just looking for light duty stuff, then you'll probably be ok with what your looking at.


If you want to be able to bust loose a big nut, then you need a bigger compressor. Dayton and Speedair both make 220v (uses less amps), 25+- gallon, belt drive, horizontal roll abouts that will put out about 7cfm @ 90psi and cost around $500. These would handle the majority of your needs.


I wouldn't hesitate to buy the IR impact tools they're HQ and last.

If for only for light maintenance, you could get by with adding a storage tank between your current compressor (Hitachi) and your tools. You could exceed the supply of your existing compressor (4.0cfm) for light duty work with the large storage tank and a small compressor. If you have additional question on air volume vs pressure, send me a PM
