Thank you Ranger for the advice. Good to know 20 gallons is good enough (makes a big difference in pricing).
As far as the recovery rate goes, i'm not too clear on how exactly it works. I'm assuming that 10.2 CFM means that it takes less time for the tank to re-fill itself as opposed to the 5.5 CFM?
I know what you mean about buying the higher rated products. I do the same for the simple fact that I think of how annoyed I would be if I skimp out on a purchase now and then 3 years down the road my equipment craps out on me and then I have to spend more money fixing it (or buying the better equipment that I should have purchased to begin with).
CFM stands for "cubic per minute". As to recovery time, more volume (cfm) means faster recovery time.
That's the one I have, except mine is an older model with a steel cage around the pulley assembly. I found that you have to be careful about the CFM rating of any impact wrench. My first one was a single hammer that needed a bit more air to be really happy, so I sold that and switched to a dual hammer version that needed less air. Also, like people have said, grinders use lots of air, but that model is fine for light grinding, and it's only a matter of a minute or so if you drain the tank for it to fully recover. C-H puts some pretty cheap regulators on their stuff, as do others. My advise would be to switch over to a set of ARO regulators & oilers once you get used to using your compressor.
I've been thinking, I'm not really gonna be doing any sanding (if I need to I can use an electric sander). So my tool needs are only going to be impact guns, air rachets and the ocational brief grind job here and there.
You guys think 10 CFM is still required or should I go with 5 CFM?
I have a Husky Pro 30 gallon. I have alot of blue point air tools. When it comes to an air compressor you want the most volume you can get for your price range along with the best motor and highest psi. Mine fit my needs for home use 120V and portable. I have to pause occasionally when using 1/2 ratchet or 3/4 impact. I could not see going any smaller than 30 gallon. I do have a snap-on lift but it's electric over hydraulic. This was the biggest I could find in 120V and with a oil pump when I bought mine. It gets the job done but that's about it. Don't forget about fittings, air separator, hose, and etc my budget was $600.00.
I have a Campbell Hausfeld and couldn't be happier with it. I went as big as I could go on a 120 volt, as 240 requires at least a 50 amp breaker. It does everything I need it to.
Well fellers. My awesome brother in law got me an Ingersoll Rand 20 gallon, 135 psi, 5.2 CFM compressor as a Xmas gift. It Got delivered today !!!
Haven't started it yet but the thing is built like a tank! From what I've learned so far 20 gallons should be enough for my needs. Changing wheels and working under the car doing exhaust installations.
Can't wait to put this thing to use man!! Now I need an air hose and air tools !!
