Air Compressor Selection

Objectives: - As quiet as possible - Budget is around $500 - MUST run on 110V. I do have a 20A circuit available - Low use, probably several times a month. Impact wrench, cooling system vacuum filler, inflating tires and occasional air hammer use (1-2x/yr) for loosening axles from the intermediate bearing. These are the two I am considering: https://www.californiaairtools.com/...-grade/2-0-hp-air-compressors/cat-20020/ https://www.lowes.com/pd/Kobalt-KOB...XwwJEAQYASABEgKn7PD_BwE&gclsrc=aw.ds Thanks.

Both of those are 230V, correct? The second one says it can be operated at 115V but the amperage would be double that at 230V.

Both should run on 110V. I just corrected the link for the first one.

Reciprocating air compressor, they all make noise. Direct drive make a higher pitch noise than belt drive. To get quiet you have to put one in its own sound proof room There is a type of compressor rotary screw or scroll that make much less noise and cost more $$$$ You do not get to combine inexpensive and quiet.

On a 20A branch circuit?
The 20A circuit I have in mind is for the furnace only; I can unplug the furnace when the air compressor is in-use.

The biggest tank you can get, and the highest pressure, like 150psi minimum. You can always daisy chain another tank for extra capacity, which also helps cool the air, which helps get the water out of the air. And ALWAYS drain the tank before you fire it up.

Yeah, I don't think any of these options are truly favorable.

I've had the previous version of the Kobalt in the OP for 12-13 years. It's perfectly fine for what you're doing. The newer version should be even better.

The Kobalt wont run on your circuit. It says [email protected] what it does not say is it will draw [email protected] and even with a 30A breaker it will probably trip the breaker when restarting at 100+ PSI. Since you are a DIY and only need it occasionally the 20 gal tank or larger will work. I am running my impact wrench on a 150 PSI max 6 gal pancake when I have to work in the driveway. Its a bit slower than using the larger 230v unit but its easy to move and runs on a 12ga extension cord. If you can find a belt driven, oiled compressor, go that route for longevity and lower cost of repair but most of the direct drives from a decent company like California will last years with occasional use.

Run a 220v circuit. Buy a 2 stage Quincy or Ingersol-Rand with an 80 gallon tank and have something that will accomplish all goals going forward. It is nice to have a compressor large enough that isn't continuously running to partially accomplish a task in high demand situations

Right on!
