Working on 85' Cutlass Supreme body & frame.
Jus purchased a Portable Abrasive Sand [email protected] compressor requirement: 2 HP, 3.3 CFM @ 90 PSI.
Heavy Duty Spray gun, Required pressure: 60 PSI; Maximum pressure: 115 PSI; Average air consumption: 10 CFM @ 60 PSI(Under body paint & Frame).
1/2 composite impact Air wrench, 1/2" square drive; Average air consumption: 6 CFM @ 90 PSI; Blows per minute: 509; Air inlet: 1/4"-18 NPT.

What size compressor do I need for these items?
3 HP, 10 Gallon, 115 PSI Air Compressor. * Air delivery: 5.6 CFM @ 90 PSI; 7.2 CFM @ 40 PSI

* Easy-start two capacitor heavy duty motor
* Thermal overload protection
* Clear view oil window lets you know when its time to refill oil
* High impact ABS shroud for maximum protection
* Easy-to-read pressure/regulator gauges indicate CFM and PSI
Or
2 HP, 4 Gallon, 115 PSI Twin Tank Air Compressor
Direct drive for smooth, consistent power.

* Powerful 2 HP motor
* Automatic shutoff
* Twin horizontal tanks
* Anti-vibration rubber feet
Thanks for your time :biggrin:

If you want to paint cars you need a 60gal tank minumum with 5hp or more for CFM quality. You also need to think about air dryers and regulators if you dont want water in the paint or sudden blasts of air when running the gun.

Thanx for the info guys.
Kinda on a budget, 3.5 HP, 25 Gallon, 125 PSI Air Compressor for sand blasting & painting frame should be fine?
No need for auto body paint.

don't use it for sandblasting it will never keep up sandblasting uses alot of air


just use power tools and sand it if it's just a frame...and yes it will do ok for frame painting


try to match the gun's cfm's to your compressor's cfm's

good luck man

I was using a 17 gallon, 1.5 125psi and it wouldn't do shit for sandblasting, ran out of air way too fast. Check craigslist, I bought my 60 gallon 6.5hp for $250 it's a cambell hausfield with a cast iron motor. Watch the bigger compressor though, some are 3 phase.
