Time to upgrade the air compressor... Questions?

[CGCINC]

All right... I'm gonna have to rethink my whole plan here!
My current compressor is like 3.7 CFM or something rediculous...

So is it the HP rating that increases the CFM rating or is it a cobination of tank size and HP?

You can only extract so much power from a 110v source. They usually max out around 4 CFM @ 90psi so one thing is only look for 220v units if you want more output.

When under 110v, they try to keep the amps 15 amps or lower which limits the amount of power you can extract from the wall. 220v circuits typically have higher max amps available and are double the volts so the CFMs you can get will be much higher.

Horsepower numbers can be manipulated so be careful looking at those numbers.

I've been researching compressors also. I know the kobalt unit you are speaking of at Lowes. It is a single stage compressor 15 amp running, not sure what the start amp requirement is, but a 30 amp breaker should be enough. It is 220volt. It will run shop tools ok (except for impact wrench), but a sandblaster really needs a two stage compressor and 80 gallon tank, which gets up in the 1100 area at Lowes, HD. The horsepower like undercut says can be manipulated. I think the kobalt says 3.5 horse running, from memory. I never looked at horsepower that much. Instead, tank size, cfm, and price. All these kobalt, husky brands, and some others, are made by campbell-hausfeld from what I've read.

I don't know lowes policy, but Home Dep. will give you 10% discount for your veteran's service, and there may be some sales at all the stores for July 4.

These days HP numbers are almost worthless, (in the consumer space) check the volts and amps to compare.
