Any of you guys running air tools of your OBA ?

[Slo.Mo.Shun]

Anyone running an impact gun out of the on board air ?

If so, what size line are you using and are you using a pressure regulator ?

TIA.

[markfif]

yeah i am running an air chuck off my 5 gal tank. I use 1/4" line.

[Slo.Mo.Shun]

Have you ever tried using an impact gun with that line ?

[16v_HOR]

I have 1/4 line in my car and run a 3/8 impact. It's enough for a quick shock to loosen wheel studs or get a top strut nut off which is all I really need it for.

[Clean PG]

how exactly does this work? do you run a line right from a spare port on the tank and connect it to the impact wrench? how do you plug the line so when it's not in use air isnt being pushed out of it?

any info on how this is setup would be appreciated, i'd be interested

[VWRedcoat]

.... quick disconnects? just like a normal air tank/compressor setup..

[Rob Cote]

I'm not finished yet, but this is part of my plan. I will be teeing off the line from the tank to the valve block with a female quick disconnect. The beauty of these fittings is that when you disconnect the air hose, they seal off their opening. This will allow me to store my air hose neatly coiled on my spare tire in the well. For shows and other long trips, I plan to carry with me an impact gun, tire filler upper with gauge and maybe one or two other items if I deem them necessary. I think being able to puff up a tire that is low, for myself or a damsel in distress will be a very handy feature to have.

i feel like this is a making a mountain out a mole hill. whats so fancy about this concept?

a metal schrader valve would be something neat to have.

It's definitely not complex. **** the factory does it (well, did it anyways, not sure if they still do) in the Allroad. One compressor for air ride, a separate compressor to fill the deflated spare.

hmmm this is something to consider...

[nickbeezy]

i have done this
but there really isnt enough air in the tank to really run a real air tool off of it. its good for a blow gun or tire inflater
but not to run **** like air impact or w/e


then disconnected

[Slo.Mo.Shun]

Thanks for the replies guys.

All I want an impact gun for is to change my wheels. I found a couple of 3/8 guns with low cfm rating and 300 ft.lbs, which is more than enough.

I am planing on using a 0-200 psi regulator @ 100 psi to make the most of my 3 gal tank and 2 480s.

[Clean PG]

i have a schrader valve on 1 of my ports but if i'm not mistaken, that is only used for input, to manually fill the tank if the compressor dies, correct? if i want something to output air for filling my tires, i would need a quick disconnect like shown near the top of the thread? can the tire inflator and coiled line be found pretty much anywhere then? i've never shopped around for this stuff, so i'm not 100% sure what to be looking for.

thanks

Use a quick disconnect on your tank. It can be used to fill the tank incase a compressor stops working or it can be used for an air tool. Depending on the size of your tank and how many compressors and types you are using you may be able to run a decent sized impact gun off of one. I know at my house i have a 5cfm 4 gallon air compressor and i can use my impact gun a little bit off of it. In my car i will have 8cfm and 8 gallons of air so i am going to be better off than at home.

The performance data for my compressors (have to multiply by 2 cuz i have 2 of them)

[Slo.Mo.Shun]

Wow

I knew OB2s were powerful, but I had no idea a single OB2 had more CFM output than dual 480s.

Dual 480s @ 100psi = 2.08
Single OB2 @ 100psi = 2.47

Dual 480s @ 100psi = 2.08
Single OB2 @ 100psi = 2.47

a single 400cc viar is like 2.4 cfm i have two

[Slo.Mo.Shun]

^^^That is only correct at 0 psi.

2 400s put out 2.47 CFM @ 100psi, but they are 33% duty cycle and 150 psi comps.

Dual 480s @ 100psi = 2.08
Single OB2 @ 100psi = 2.47

They kinda kick ass, plus they draw a little bit less current and its only a single unit instead of finding space for two. This was my dilemma when trying to choose between 4 480's or 2 ob2's and the ob2's just win.

a single 400cc viar is like 2.4 cfm i have two

A single 400 is 2.5cfm at 0psi, but only 1.27 at 100psi. I don't like the 400's for a few reasons:
1 - they are only a 33% duty compressor in the pressure range that we fill from and to
2 - they draw 26 amps EACH
3 - they are only good for 150psi (they can probably do higher but its going to make them fail quickly)

So to get the same cfm as my 2 OB2's you would need 4 of them, with a total amp draw of 104 instead of 70 for the OB2's, you would need room to fit 4 of them with plenty of dead air around it for heat dissipation and it would only fill to 150.

^^^That is incorrect.

2 400s put out 2.47 CFM @ 100psi, but they are 33% duty cycle and 150 psi comps.

Just what i was thinking, get out of my head

We are both building setups right now, so we are obsessing over the same stuff.

Its just the OCD...

I have the exact same tank as you by the looks of it (No drain port?) I'm looking at air tool fittings but I'm unsure which coupler etc I need. I have two spare ports on the end of my tank, one is 3/8 and one is 1/4.

Was looking at this > http://bagriders.com/modlab/products...L-COUPLER.html Anyone know what the actual threaded end size is? I think the 1/4 refers to the plug in end?

I want to have an air line constantly fitted (As it will be hidden) so maybe I should use something different? A PTC on the tank with an airline pushed in, and then a fitting like the above on the end of the air line to have it closed off/tools fitted?

It's 1/4" NPT

Thanks Will. PS: Not forgotten about buying the other fittings, just got busy with someone who threatened my Dad.
