On Board Air

[goodtimes]

You may want to PM Goodtimes on this forum too - he has one and also complained of the duty cycle I think (shuts off pretty quick in summer time here in AZ). He has 33" tires on his Rubicon.

Yes, I did run into a duty cycle problem with mine the first time I used it. But, to be honest, I was likely due to enviromental issues. It was 108* outside (Florence Junction in July), and my compressor is mounted under the hood of the jeep....making it even hotter. I filled up 3 of my 33" tires from 10psi to 35psi before it overheated and shut down. I have not had a problem with it since then (also, I have not been trying to air up when it was that hot out.....). The next time I need to air up when it is that hot, I will not go to 35psi...I'll stop around 28psi which is plenty to get my 4000 pound jeep home on it's D rated tires.

I use the ExtremeAir unit from Extreme Outback Products. At 4LPM it will run most air tools without a tank. It is also very quiet, more like a V8 rumble than 4cyl scream.

I think Scott's compressor it quieter than mine (mine only moves 2.4Lpm).

Scott, what is the amp draw on yours? Mine will pull 30 amps (FLA), at 12 volts.

I , like Scott, am running the Extreme Air from Outback products. I like it very much and I have a 2.5 Gal Tank in the bed that i work off of instead of the compressor itself. I can run air tools, but I think they would work better if I had more stored air and better quality tools. Here's a couple of Pics' Tu Comps , Suty

Superflow

I used mine again this last weekend. Aired up my 33's and my brother-in-laws 31's. I carry this thing in the Land Cruiser all the time now. Got one for the Jeep. Got one for my parents 4runner. You really can't beat this thing for $59.99 at Pep Boys.

Sorry I missed out on the $24.99 closeouts but this thing is worth $59.99 for sure.

Someday, after more important mods, I will pony up for the Extreme Air.

I missed the 24.99 deal also! Still bought one at the higher price, haven't used it yet but from the sounds of it it will work a lot faster than my trusty TruckAir (100% duty cycle but takes 45 minutes for all four tires).

I just carry a 10lb Co2 tank. I got about a dozen fills of all 4 tires from appx 18psi to 35psi on one tank. I didn't keep real good track of how many fills I got on the last tank. Plan on keeping better record on the next one.

Can they be mounted horizontally? (these MV50s)?

MV-50 and OBA

I've been thinking of setting up an OBA system for quite some time. I have picked up an MV-50 when they were $24.99 US.

Today, I was driving by a store called Parts for Trucks and went in to see what they had. They service and sell parts for big rigs. Well they had 2 styles of air tanks that are used in the air brake systems for big rigs. From what I understand, the brake systems typically run between 100 to 125 psi. I picked up a rather large tank, 6.4 Gal, for $49 CDN taxes in! :jump:
The only catch is that the ports are 3/4", 3/8" and 1/4". Not an issue since the store also carried a full line of bushings, fittings, adaptors, etc...

I'll post up a few pics of the tank once I get my digital camera back. For the time being, I'll be installing the sytem and using the MV-50 as a compressor. I intend to upgrade to the ExtremeAire unit once the funds are collected. The plan is to install everything so that once I can afford the ExtremeAire I'll be able to just remove and replace the MV-50. All the relays, circuit breakers, wiring, tank, hoses and fittings will be able to handle the ExtremeAire.

My main uses will be to inflate tires, activate a front ARB in the future and run some light duty air tools.

I'm not sure how long the MV-50 will last or if it can be mounted on it's side, but for $24.99 why not give it a try?

Cheers :beer:,
