Shopping for a on-board air system
 

Lookin' for advice ...

Converting the a/c compressor is not a option.Since, I added a second alternator for welding..

The duty cycle must be high,since I wanna air 35 tires.

Heres one I'm interested in.....

Anyone running this one and/or something similar?

I ran one of those with out a tank and it sucked ass...Might be better with a tank...The compressor didn't last long. But that might be because it was and still is mounted under my winch and it went swimming a few times lol..

Thanks for the input. Before I spend 369.95 .Just wanna make sure it'll do the job.

Their specs they claim it will air a 35 tire from 15psi to 30psi in 2min.20sec.

I guess thats good?:confused:

What about the CO2 tanks?? Anyone using this setup and where in cincy can you get them filled?

Heres one on Ebay. Seems pricy

Thats pretty slow. If you notice the CFm is what is doing the work for the compressor. So with only 2.54 CFm thats a lowerend rating. I think my stock Sanden compressor puts out like 8 ish CFM and I have a 7 gallon tank. I can time how long it takes to fill my 35" from flat and I think its right at 2min 30sec.

CO2 air seems to becoming more popular but I don't like having to go get it filled and paying each time I do that. Maybe I just use mine too much to ever think about CO2 air. Just some thoughts for you.

BTW I obviously have OBA and I am close to having my OBW done. maybe a route for you since I made my OBA for about $125 or $150.

Yep pretty slow... Been sittin' at the putor the last few hours looking at options. Viair is all over,I'm finding better models and pricing than E-Bay.

The search goes on...

Yeah Viair is very nice stuff, its just the fact that it isn't belt driven so there isn't enough power for 12V. I have two Viair parts, pressure switch and a manifold.

There are many similar write-ups to this one on naxja IIRC, this is just the first one I found:

You can't beat a York for oba, it will do whatever you ask of it.

I remember seeing an article where the A/C compressor was operated by a 12volt winch motor. Had the benefit of the A/C on-board systems but utilized a separate motor, not a pulley directly off of the engine.

There was discussion on the thread as to how much electric current draw there was and if a battery upgrade was needed or not.

I'm not an electrician or much of a mechanic. With that disclaimer in mind, I would think if you are able to supply current for an onboard welder, you could supply the 12V motor for the compressor. Especially if you are only running one at a time. If you are welding a broken part, air in a tire can probably wait.

Sorry I do not remember where I read that thread to post a link. I'll look at a couple of other site to see if I can find it.

This is not the homemade version I was talking about. It is a commercial product using a winch motor. It may help with the idea I saw, I just haven't found the original website thread I mentioned earlier.

that sounds like a decent idea...
i would think you could use a starter motor to run the compressor with a small tank, then the recovery time would be short and not take to much power...
just my 2 cents
:beers:

There's a place on Glendale Milford Rd that can test and fill a CO2 tank.

Some welding shops will refill them and any paint ball shop can refill them as well.

Everyone,thanks for the info... Never knew about the Oasis HP1000, man that thing is bad azz. It's weight and price of 825.00 will keep it off my rig.

So far this one is the best deal I've found...

The specs look good and looks like the kit has everything you need to install.

I'll check on the co2 tank refill.

The search continues..

Are you used to working with a shop air compressor with a 20+ gallon? If so this thing will not be fun but it will run run and run some more. Plus it can run while you engine isn't running, just for a little depending on your battery.

Don't mind it running while airing the tires.I would like it faster ....I'm amazed the price jump on these systems. They go from 400 to 800 quick.

I'm in no hurrry.. Need to have somthing in the heep by Feb oh-ten.

might want to check Viair's website first. I looked and that model, might leave you dissappointed. Here's the 10007 specs. Multiply those times x4 if your airing up and down for trail/street.

450C Tire Inflation Rates
Begin/End PSI 31" X 10.5"
0 To 30 PSI 4 Min. 05 Sec.
15 To 30 PSI 2 Min. 10 Sec.

Begin/End PSI 33" X 12.5"
0 To 30 PSI 5 Min. 30 Sec.
15 To 30 PSI 2 Min. 50 Sec.

Begin/End PSI 35" X 12.5"
0 To 30 PSI 6 Min. 55 Sec.
15 To 30 PSI 3 Min. 30 Sec.

....
 

The 400c #10005 has faster inflation times.

400C Tire Inflation Rates
Begin/End PSI 31" X 10.5"
0 To 30 PSI 2 Min. 28 Sec.
15 To 30 PSI 1 Min. 25 Sec.

Begin/End PSI 33" X 12.5"
0 To 30 PSI 4 Min. 00 Sec.
15 To 30 PSI 2 Min. 00 Sec.

Begin/End PSI 35" X 12.5"
0 To 30 PSI 4 Min. 50 Sec.
15 To 30 PSI 2 Min. 20 Sec.

never mind, I'm guessing the 33% cycle isn't what you want.

That is how my setup is that I have been running for several years now. I run an aluminum York driven by a winch motor in my bed mounted tool box. Works great, but weighs in at a thin 43 pounds. I love it.
