Is my Husky/Porter Cable ‘Easy Air to Go’ 2 SCFM @ 90PSI/135max big enough to run an air tool such as a 17 SCFM die grinder. Thanks.

Husky easy air to go air compressor


Hi Bret:

The easy answer is…yes it will. The tougher answer is not very well and not for but a few seconds before you run out of air.

If you’re relying on your little compressor to provide enough air to use your die grinder for long periods of time…and particularly if you are in a hurry, then you are going to be disappointed.

If you’re running a die grinder that sucks 17 CFM of compressed air at 90 PSI for a production environment…that is, using it for hours at a time, then you’re going to need at least a 5HP compressor with as large a reservoir as you can afford to have sufficient air supply.

Is 5 HP Craftsman big enough to run a Devibiss starting liner spray gun.

I have a 33 gallons 5 HP air compressor craftman. 12 scfm @ 40psi 10 SCFM @ 90 psi can I use this compressor with this gun.thank you.


Ray, I would like to say yeah, or nay, to using that air compressor with your gun, but I cannot.

You give me the specs of the air compressor. That’s good. You didn’t give me the flow requirements or compressed air pressure requirements of the gun, so there is no way for me to tell.

What are the gun specs please?


How big an air compressor and how many scfm do I need to take off a truck tire?


Oh… I dunno… maybe three hundred million! 🙂

Or, you could check the specifications for the impact wrench you are planning on using, both for the air pressure required (measured in PSI) and the flow required (measured in CFM).

You see, a small air compressor can deliver the force necessary for most air tools. Typically, and air tool will run at around 90 PSI in terms of air pressure required.

What you and I don’t know is what is the flow rate that 90 PSI is required at for the air tool that you plan on using?

Get that info, and the question is answered. Since I don’t know what wrench you are using, nor the specs for it, I can’t be specific. Sorry.
