Craftsman 3hp 150psi 15gal ????

[legenddrug]

I finally going to get a compressor for my garage, but not sure about this model being the right one. What I'm looking for:

1. must be able to run a 1/2" impact wrench
2. vertical tank--limited space--
3. 110 to 120v
4. affordable

The impact wrench is my main concern because most require right around 4 CFM

15amps
3hp motor
15 gal tank
150 psi
4.9 SCFM at 40psi
3.5 SCFM at 90psi

Will this compressor fit the bill?

Also, any reasonable 1/2"impact wrench suggestions? ~$80

Thanks in advance for the advice.

I would go for the 33 gallon size. This will give you more CFM to use your gun.

On sale now! Free air tool kit, too:

For 80$ look at campbell hausfelds... The IR guns (the 231, original) start at 110 and go all the way up to almost 300. The CH impacts are designed here, built in taiwan, and have a decent warantee on them. Id also consider, like BMW said, getting the craftsman compressor with the free air tool kit. Get as much CFM as you can either afford or have the power for. You mention 110/120, so probably no more than 6 cfm or so. Keep in mind you wont be getting the full torque out of your air tools, but they should run. IF possible go for an il lube model, as oiless tend to be loud.

I have a 33 gal oil-less that works well for my needs... basicalyy impact gun stuff. I went to Lowes and bought a Campbell Hausfeld Ironforce 1/2 impact. It is a twin hammer design, generates 500+ lb/ft torque, has a three year warranty and is made in Taiwan instead of China. So far, it works pretty good, although it likes to be run at about 125 psi. It cost about $65 IIRC... heavy as hell, though.

basically my option at this point is the 15 gal 3hp model, so will it run an impact wrench well enough to to lug work on cars?

Yes, it will handle an impact, but you may have to wait for a bit of catchup after every few lugs. Also, Since the compressor doesnt put out what the gun needs @full load, you wont be seeing those sort of torque numbers. My friend has a compressor similar to this one, in terms of air output, and It struggles running his air ratchet. Just keep in mind you will be playing catchup running certain tools, but an impact gun sure is nicer than a breaker bar for doing wheels lol

Check out the thread in "general Discussion" titles something about "looking for a lift and a compressor" for a bit more info

The CFM rating on the compressor doesn't have anything to do with the CFM rate on your impact gun, if you're using it while the tank is full. The CFM rating on the compressor is a measure of how fast the actual compressor will fill the tank. Pressure is the #1 factor for impact guns, but there isn't much that I come across that 125# won't take off. If you are using die grinders, sanders, drills or other rotary tools, tank size is your #1 consideration.

I have to disagree with some here.. I gave away my larger compressor to my father n law and got a smaller unit.. I got tired of waiting for the tank to fill up.. I only needed mine for smaller jobs.. so I am happier and dont have a problem with running out of air with my air ratchet and such..

Thats why I turn my tank off... My system leaks about 5 psi a day from this one threaded fitting, no big deal. I just turn off the tank and I dont have to wait for it to pump up. Also, What are you doing with this ratchet? One or Two bolts here and there or like major disassembly?

Jim, I used to do the same thing and then started to get worried about the water and rust issue.. so I drain my tank every time to slow down that process. But maybe I am just a worrywart..

Yeah, I share the same concern, so I shut off the tank As the last part of cleanup after a job, so I know the air inside has cooled and the water has condensed. The tank is usually cool to the touch after about 10-15 min from the last cycle, I give it another 10 min or so, which, Im guessing is enough time, because a ton of water comes out of the drain... If I go back 10 min later to drain water again, Virtually nothing comes out. Cleaning up and putting tools away usually takes 15-20 minutes, so the timing is perfect.

By shutting off the tank, your saving your compressor from having to pump up all that air as well. IDk, Whatever works man, what ever works
