Compressor to run 1" impact

[Drummer79]

I need a compressor to run a 1 inch drive impact gun. Something semi-portable or gas powered would be awesome. Suggestions?

Most service trucks use something like this for changing big rig tires with 1" impacts.

How long/often do you need to run it?

[Drummer79]

I'm not in the tire business or anything but I do the brake work on my 3 dump trucks when needed. I don't use it often enough to make 2 grand a good investment :eek:

Almost any compressor will work you just need a big enough tank to hold the air.

Back in the old days I pulled a 45 foot covered wagon that i installed extra air tanks for just that very thing. So I ran using the truck compressor.

Worked rather nice for changing the odd tire also great for brake jobs as well.

A single stage compressor will work with an extra tank of at least 60 gallons, if you run out of air just wait a few minutes to let the compressor catch up.

I have seen cfm needs of between 16 to like 9 with most in the 10 to 12 range for one inch drive impacts.:grinpimp:

Cool. I've already got a hose connector on 2 out of 3 of the trucks...so I could just take an old big air tank to have on site and hook up the truck and let the truck pump fill the big tank along with the truck tanks...
:smokin: I love it when a plan comes together

You might want to put a regulator on the line before it goes into the impact gun.

Some guns just don`t like any more air than 90 psi for long times.

Glad I could help, I hope they are newer and have the outboard drums , it was a pita to do the old style where you had to pull the axles to get the drum off.:D

I think I'd look into one of those cordless rattle guns. I know you can take all the wheels off a 8 axle dump truck with one. I'd go for a 36 volt Dewalt or a makita maybe.

been searching and looking for an answer. I am looking to run a basic air tools set up. All the compressors in my budget are 4 cfm @90psi, will this be enough to run a 3/8 impact, angle grinder ect??

Nice try but no. :laughing: Id like to see a video.

Edit: http://www.dewalt.com/36v :flipoff2:

325 foot lbs MAX. :laughing: they are good guns no doubt. They will take the tire off your wheelin rig but they WILL NOT remove a lugnut from a dumptruck. This is almost laughable. Sorry.

technically, it will "run" the tools you want.. it will go like this..


RAP RAP RAP RRRRRAAAAAAAAAAA RRRRRRRRRRRAAAAAAAAAAAAAAA WWHHOOOOOSSHHHHHHHHHHHHHHHH

angle grinders will eat up a ton of air. same with impacts.

those compressors like your looking at will run nail guns and finish guns all day long. It'll even pump up your football, tire and maybe the occasional clown baloon. It is not practical for wanting to run air tools. You will be sorely disappointed. Search craigslist for an older, larger compressor. Your going to want something 10-15 CFM range at 90 PSI. THIS IS IMPORTANT!!!! smaller compressors can/will be rated at 10-15 CFM but they will be rated at 40 psi.

[Wyoming9]

It all comes down to how much cfm at the pressure needed can be delivered to the air tool of your choice. Impact tools are not to bad but things that run longer periods of time .

Like grinders or sanders consume air like anything. A compressor on the small side can be used if you have a big enough extra storage tank. I knew some people that ran a shop with a 2hp single stage compressor but the tank was 120 gallons.

Being we don`t know what your budget is I would say keep looking for a good used single stage one with a single phase motor. two stage would be nicer if you plan to spend a lot of time grinding.

[freerider5.0]

i really don't plan on doing a lot of grinding. a little at most, I will be using the impact on things like atv wheel lugs, misc truck stuff. i am looking to spend $150 or less. I found a decent used one on craigs list. I am just going to keep looking

[FullsizeYota]

two stage would be nicer if you plan to spend a lot of time grinding.

a two stage is really only good for higher pressures (PSI) and not much for CFM, albeit most two stages are large(r) and usually have a higher CFM than a single stage..

a single starts to sign off around 120 psi, a two stage will be north of 150

[M CRISIS]

I have seen users, even with a big compressor, starve their larger air tools by using too
small of hose and connectors. Typically the tool gets the blame for being underpowered.
You can have all the air in the world but if there is a restriction anywhere in the line the
air tool will not perform as expected. So be sure to use, at a minimum, 1/2" hose with 3/8
fittings to assure proper air supply for your larger guns.

Wow I must be real lucky because my 2 stage compressor puts out more than twice the amount of CFM at 90 psi then my single stage.:D

I'm sensing some sarcasm.

2 stage pumps are used in more industrial applications. industrial applications need more CFM generally. so they go hand in hand on a 2 stage, who needs 175 psi, but only 5 cfm?

single stages are more non-industrial. They work, they pump air but not to 175 PSI, most sign off around 120-130. then the pump starts to over heat, they are not designed for that type of pressure. Just the nature of the beast. if your not needing a whole lot of pressure, you more than likely wont need a ton of CFM, there are exceptions, sure but this is the general idea.

[Wyoming9]

My two stage compressor has installed a single stage pressure switch that shuts off at 125 psi

I agree I don`t need 175 psi but I do use every bit of the 26cfm at 90 psi on some days:smokin:

If your going to run a 1" impact don't forget to use a larger diameter air supply hose. Large impacts need plenty of volume.

[dopeassjackson]

a 1in impact gun is overkill for a dump truck. 3/4 with a 3/8th in line will work just fine for taking off lug nuts. a little oil in the gun goes a long way. the only time i have used a 1in gun and 1in hose was to spin a rusty loader bucket pin, those times required massive amounts of heat.

[blu125GQ]

In my tyre retail stores down here in Australia, we only use 1/2" & 1" rattle guns. 1" guns last a LOT longer than 3/4" guns for a modest increase in price. Obviously, with lug nuts, space is not a problem...... ;)

[silvrjeepr]

I've used my 1" drive impact once or twice with my kobalt 3hp compressor. It works fine as long as you're not trying to rattle down more than a nut or two in quick succession. I'll admit that the old yellow 2 stage compressor kept up much better, but i can still crank the torque on a big nut or two before it needs a break with my current setup. Good enough for my few and far between uses...


x100 on the larger hose. You're just pissing in the wind otherwise regardless of the compressor used.
