if you wanted to run a 1/2" impact gun.

something that can keep up with the air supply demads the gun needs.

currently i'm looking at 2. one is a CH 3HP belt drive pump with 16 gallon tank. and the other is also a CH 5HP belt drive pump with 22 gallon tank. and there's about a 140 dollar diffrence between the two.

i'm kinda leaning toward the 3HP one for the price but some might say the 5HP is better.............

any suggestions?

 

if i was you i would get a stronger one, trust me in the long run you'll be saved from mad headaches

 

SCFM is more important when looking for a compressor than hp. Get the one that is higher

 

Go with the bigger one. You'll kick yourself if you don't

 

A 1/2" impact gun will empty that 16 gallon tank in a heart beat. The air compressor will kick in every few minutes. You're better off with the 22 gallon one or bigger if you can afford it.

 

Spend the money on a larger tank. The size of the compressor isn't as important, except for the fact that a larger compressor should last longer because it's working below it's max to keep the tank full. In the long run, $1-200 isn't that big for a tool that you will have for a long time.

 

I have a 5hp crafstsman with a 20 or 25 gal tank- i forget which. Good compressor for my 1/2 inch gun. Good warranty too, you can just take it back to sears, tey that with a CH. Something to consider is that if you go larger than 20 or 25 gal. you might not be able to tramsport it in the car if need be.

 

there both rated at 125psi. i'm sure the regulator can be changed to get 130-140psi out of it.

i think i'll go for the 5hp/22gallon one........thanks......
