Will this compressor run my die grinder?

Will a Husky/Porter Cable 'Easy Air to Go' 2 SCFM @ 90PSI/135max run an air tool such as a 17 SCFM die grinder. Thanks.

Hi Bret:

The easy answer is...yes it will.

The tougher answer is, not for very long before you run out of air and have to wait for the compressor to catch up.

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.

If you use the grinder for a minute or two at a time, with lots of breaks for the air compressor to catch up, then you'll probably be OK with the small unit though you want to be well aware of it's duty cycle.

Cheers,

Bill

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?

Cheers,

Bill

Air Compressor big enough to sray gun.
by: Ray

Hi bill me again Ray sorry for for not sending the spec on the sray gun.
I have a 33 gallons 5 HP 240 volt craftman air compressor, 12 SCFM @ 40 PSI, 10 scfm @ 90 PSI.
Can I use my DeVilbiss starting liner spray gun
with this compressor.
Spec on gun.
30 psi inlet pressure.
Delivers 10 psi air cup pressure.
at 13 cfm.
thank you...

I'm still not quite sure what the flow DEMAND of the paint gun is. However, based on what you have provided, I think your compressor should be OK.

One thing you do want to check is the duty cycle of your air compressor, if you are planning on using it for production. If the compressor isn't 100% duty cycle, then you will need to stop it for 30 minutes every 30 minutes to let it cool.

Cheers,

Bill

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 air tool you are using, nor the specs for it, I can't be specific. Sorry.

Cheers,

Bill

Kobalt cutting tool air demands?

by Jamie
(festus, mo)

I am trying to use a Kobalt cut off tool with my air compressor. It is a craftsman 25 psi 3 gallon compressor. The kobalt tool requires 90 psi working pressure... The tool stays going for about 1 minute then quits moving the cutting attachment. help please?

Hi Jamie:

It sounds as though you are running out of compressed air.

You say the tool needs 90 PSI working pressure. You also say that your compressor is "a craftsman 25 psi 3 gallon compressor".

Two things you need to check.

What flow does your air tool need at that 90 PSI, and, is your air compressor only capable of putting out 25 PSI? I suspect you meant 250 PSI (maybe?), but since you don't tell me what the HP of the compressor is, I can't even guess what the discharge capacity is.

Cheers,

Bill
