Gentlemen, Time is money and with the group I run it I do not want to be the last truck ready to venture on. Your stated times are far quicker than others I have talked to as well as ARB. I offer the following for a comparison of the speed and capacity of the Powertank. Thanks
This first Tire Air Up chart tells you how fast a Power Tank will air up YOUR tires and how many of them it will inflate based on the various Power Tank sizes. You'll notice that, unlike compressors, all Power Tanks regardless of their size, inflate at the same rate of speed.
First, locate your tire size in the left column. Then determine how much air you are adding from trail pressure to street pressure and find your section along the top row. Each section (10, 15, 20 psi) shows your air up time and how many tires you can fill based on your Power Tank size. Note that these numbers are fairly linear so if you need to calculate tires adding 30 psi, halve the amount shown in the 15 psi section.
| If you add 10 psi | If you add 15 psi | If you add 20 psi | | | | | | | | | | | | |
| | Quantity of Tires | | Quantity of Tires | | Quantity of Tires | | | | | | | | | |
| What's your tire size? | Here is your inflation time: | PT05 Tank | PT10 Tank | PT15 Tank | PT20 Tank | Here is your inflation time: | PT05 Tank | PT10 Tank | PT15 Tank | PT20 Tank | Here is your inflation time: | PT05 Tank | PT10 Tank | PT15 Tank | PT20 Tank |
