OBA tank vs no tank: How long does it take to fill your tires?
- Thread starter jjvw
- Start date
What would you use the tank for? If it is connected to the pressure side of the pump and you don’t have any special vaLving then it would empty just the same when filling tires?
The tank is used for things that require high pressure, airing up tires doesn't so the tank isn't needed. Have you been taking notes?
Yes, you would need an valve, preferably a solenoid.
When full, it's a second source of air; which can be used (with the compressor) or stored for later.
When empty, it can be isolated; because of a leak or to reduce compressor run time.

Notes? Nah. What high pressure things are you referring too? The only purpose, for me, would be reseating a tire bead. But there are ways to do so with out having a tank. Tools? Other than my die grinder I have not touched my air tools in a very long time. My lithium powered tools run circles around my air stuff.
If a tank makes sense for you then have at it, there is nothing wrong with that.
The bead is a great example, lockers obviously and air tools for like 15 seconds. I took out my tank and I agree, nothing wrong with doing it either way.
I sometimes just open an "incognito" tab or another browser so I can check before I post. A few people that post often have me blocked and I think its a disservice, especially to newer Jeepers that might not understand the blocking feature to parrot another response if it's correct. Just me, I don't feel the need to re-answer a question and if I have anything to add and I try to mention the person that answered in the first place that I agree with regardless of their post count or how I feel about them personally. Its a bit of an inconvenience but if it keeps people happy then Jeep on.
I do this also but it still requires you to go to a different window or page. Just a PITA IMO.
You stop electricity by tying a knot in the end of the extension cord, don't you?
That only stops lightening strike surges.

Who was making them heavier?That only stops lightening strike surges.

edit- Facepalm because you don't know the difference between lightening and lightning? Hah your ownself.

Ok, I've got some numbers
Particulars:
ARB dual compressor
Viair 2.5 gallon tank
Viair air chuck with gauge used for filling
ARB quick deflator used for deflating
Starting at 8 psi to 25 psi
35 x 12.5 x 15 Mickey Thompson Baja Boss's
15 x 9 Trail Ready Beadlocks
DR - Driver Rear
DF - Driver Front
PF - Passenger Front
PR - Passenger Rear
Test one - filling the tank
It took 1:36.03 for the compressor to switch off, gauge in jeep said 170 psi, compressor is rated to 150 psi and gauge in jeep was always right on when my old 200 psi viair 480C shut off at 200 psi.
Test two - All valve caps removed and no tank
1:28.16 - DR tire fill
0:12.19 - Time between DR to DF tire
1:27.72 - DF tire fill
0:21.02 - DF to PF tire (phone app switched on me too)
1:30.61 - PF tire fill
0:13.65 - PF to PR tire
1:27.26 - PR tire fill
6:41.65 - Total time
Test three - All valve caps removed and starting with full tank
1:03.26 - DR tire fill
0:11.24 - Time between DR to DF tire
1:30.65 - DF tire fill
0:15.61 - DF to PF tire (phone app switched on me too)
1:26.76 - PF tire fill
0:09.53 - PF to PR tire
1:27.90 - PR tire fill
6:05.38 - Total time
Test 4 - Removed and installed all valve caps with full tank
0:09.30 - Remove DR cap
00:56.04 - DR tire fill
0:21.12 - Install DR cap move and remove DF cap
1:18.62 - DF tire fill
0:25.50 - Install DF cap move and remove PF cap
1:20.04 - PF tire fill
0:21.36 - Install PF cap move and remove PR cap
1:19.11 - PR tire fill
0:12.16 - Install PR cap
6:23.29 - Total time
Test 5 - Removed and installed all valve caps with no tank
0:10.55 - Remove DR cap
01:29.64 - DR tire fill
0:19.01 - Install DR cap move and remove DF cap
1:32.47 - DF tire fill
0:23.86 - Install DF cap move and remove PF cap
1:35.06 - PF tire fill
0:23.70 - Install PF cap move and remove PR cap
1:34.84 - PR tire fill
0:09.01 - Install PR cap
7:38.17 - Total time
Notes on results: for test 5 the compressor would shut off between tires, for all the other tests the compressor ran the entire time.

I wonder what the difference would be with a York compared to the ARB? I'm sure the tank/no tank part wouldn't matter.
So if I read that right the tank aired up previously to 170 psi only saved 1 minute 15 seconds when used as you would in real world. Comparing test 4 to test 5.
In other words from the time you clip on the chuck until the compressor turns on is about 9 seconds?
It kicks on as soon as you pull the trigger.
On test one I could move between tires enough to keep it on except when I went around the front, it shut off on that one.
With the tank it runs continuously until complete.
I should say Mrs App ran the timer for the last two tests so I didn’t even see the results for them until sitting down at the computer to input them.
Usually am not racing when I fill so all the times are reasonable
Thanks for running those tests. There are many interesting aspects but the one that's easiest to see, since test two and three the compressor didn't shut off that means that the 1:36 compressor run time initially filling the tank saved 36 seconds filling the tires. That means that running the compressor to high pressure is over 2.5 times less efficient than just filling the tires at low pressure. If you count the time to initially fill the tank the compressor ran a full minute longer total with the addition of the tank and some time at higher pressures. I'd say that more than answers my question which was really more about overall wear and tear. A minute here and there isn't much to me.
