My onboard air system
- Thread starter tobiism
- Start date
All four with the Morrflayte system. I ran 1/4" truck air lines into the tub and they're tucked next to each seat.
Version 2.0 will be removing the mesh panel in my fenders, making that a push to open latched hatch with QD air and Anderson connectors.

If you haven't already can you time airing up one tire vs airing up 4 tires. I'm curious to see if there is a benefit to the 4 tire system.
My benefit is I can flip on the air compressor and put recovery gear away or pick up trash...do other things while it airs up. Usually takes about 8 to 10 minutes to air up from 3-7 psi to 28-32.
I need to figure out how to build an Arduino relay box that'll shut off the compressor when it hits a certain pressure. I can put a pressure sensor on my manifold under the hood. That'll be v3.
We also pull the wife's JK up close and inflate her tires.

Some of the numbers in this thread are much faster than what would make sense, yours seem about right.
I spent some time trying to find numbers for filling a 35" tire on a 15" wheel and most are saying 1.25-1.5 minutes per tire with single inflation. This matches the numbers I tested a while back. (all using arb dual, which is supposed to be faster than twin viairs). I'm not seeing how 4 tires can be filled in under 4 minutes.
It's all about volume. I have two separate compressors providing air to each side of the truck. With a 3/8 line going to each manifold at the seat that then splits down to quarter inch. Your dual ARB compressor has one quarter inch Outlet there's no way it can compare even if it has slightly higher numbers
I like the idea of the cutout relay. I was thinking about building something like that last night
I've been looking at the EGOI dual because it includes that cutoff capability
Be great to figure out a simple circuit with a pressure transducer/sensor and a relay.

There was a company that was selling a system that did that a while back. Lite Brite was running it years ago.
I'm surprised that if going to 3/8" lines would allow people to fill tires in 2/3's the time that ARB wouldn't be selling 3/8" fittings and hoses.
Problem is everyone wants $250 for $20 worth of parts. Or they add bling like Bluetooth and an app.
I want simple and cheap.

I can't speak for arb. All I know is I'm happy with my system and I'm certainly not up here lying about it
I like the looks of that. I was talking to a buddy of mine who works in the special equipment maintenance field and he says he has some normally closed pressure switches that are adjustable and I was thinking I could use the normally closed to control the ground to the air compressor relay so when it reaches the determined pressure it opens and kills the ground of the relay which would shut off the pumps
Gonna try one of these on that suggestion of an adjustable pressure switch.

Unless these people are also changing their Schrader valves to something larger, then not much is going to change with larger hoses and plumbing.
When I was running one quarter inch Airline out of the manifold to run to all four tires it would take about 11 to 12 minutes to fill all four.
Now, would I have gotten the same impressive result if I had switched to two quarter inch Airlines off of the manifolds instead of 3/8? I don't think so.
I'm just showing people what I built and what my results are.
I would like to try some of power tanks larger Schrader valves that they manufacture but don't want to tear my beadlocks down to install them
Also I'm a plumber and I can tell you that if I ran a quarter inch water line to four faucets and turn them all on at the same time I would have markedly less flow than if I was to run a half inch line to all four faucets even though they all have the same inlet size of a quarter inch on the inside of the supply hose to each faucet.

I wasnt sure if I ever really timed it with 37's, I know I did w/ 35's, I ran home at lunch and timed it to make sure I wasnt talking out of my neck, I wasnt too far off
I started at 7psi took 6:04 to fill to 27psi.
Then i aired down to 7psi it took about 4: 30ish, pic didn't take b/c it blinks when pused...
I then did just one tire, from 7psi to 29psi was 2:01.
A few pics of my set up. I have a 6 port manifold w/ air chuck at each corner & a bleeder on the grill. I keep the hoses in a bag w/ recovery gear.
