CO2 Air Systems for Offroading, 4x4, Desert, Sand, Construction, RV, and Commercial Use
On board CO2 tank systems offer incredible convenience to users who can air up tires faster than most any other way even when out in the middle of nowhere. No more hoping a gas station has air or a working compressor and no more buying/carrying air compressors that are costly and take quite a while to air up tires. Plus you can use these at home and you can use them to power air tools anywhere you take the tank.
A 35x12.5 tire can be aired up from 5 lbs. to 30 lbs. in under 2 minutes per tire and you can inflate your tire up to forty (40) times using a 10 pound tank (according to the companies selling the systems). By the way, it’s easy and convenient to refill your tank. CO2 tanks and refills are very common – they’re used in the beverage industry, off roading and paintball as well. Beverage companies and industrial gas companies will refill these tanks. The cost to refill typically is in the $10-$15 range (YMMV). Google “CO2 tank refilling” for more info.
Avid off-roaders usually consider CO2 systems to enable them to air down and back up anytime, anywhere and do it quickly but many have been put off by the high price. Now there's a solution that is equal to or better than the CO2 tank system suppliers at the lowest possible cost. And the good news is you can build your own system and buy all the stuff directly yourself for the least expensive CO2 tank solution.
The Good News
You can pick and choose and put together the best, most cost effective system for your needs. If you want a 10# (pound) tank, which is the most common, you can get it. And if, for some reason, you want a 15# or 20# tank, you can buy them too. It’s your choice.
Start with the tank, then choose your regulator with hardware,
Power Tank and Outback Air are the two primary companies involved in selling on board air systems. Tanks are available in different capacities (weights) and the most popular tank size is 10 pounds (which holds 10 pounds of C02). Here are some of the packages these CO2 system companies offer – these are the package prices to beat:
Powertank
PT10-5200 Basic System with 10lb. tank (“bottle”) is $389.95
POWERTANK - CO2 Air Systems
And if you want a boot and a mounting bracket the package (PT10-5240) is $439.95
POWERTANK - CO2 Air Systems
Outback Air
Outback Air XD CO2 System Combo (includes a bracket) is $265.00
Outback Equipped | Outback Air CO2 Systems | "Is Your Rig Outback Equipped?"
Both companies offer 15lb. tanks which are even more costly.
Powertank offers a gauge – shouldn’t the regulator have a gauge? The Powertank regulators typically come with a gauge on the regulator but the truth is no gauges are necessary since tank pressure is constant at ~800 psi when there is liquid CO2 left in the tank (the regulator will read full up until it’s empty). How do you know when to refill? You can measure what's left by weighing the tank. An empty tank with a regulator attached weighs ~15 lbs. and 13 lbs. without the regulator. So a 10lb. air tank and regulator with a fresh charge of liquid CO2 weighs ~25 lbs.
This is an a la carte solution, a menu that allows buyers to pick and choose and buy what's needed – here are the details:
Tanks
10# tank
These are brand new aluminum tanks with a CGA-320 valve (this is a standard tank and valve – the same as those used by the above industry suppliers). These are brand new aluminum CO2 tanks not reconditioned steel tanks. Every CO2 cylinder is produced from high strength aluminum alloy 6061-T6. These tanks are popular because they are not as heavy as steel tanks and they do not rust.
A carrying handle is included on the 10, 15 and 20 lb. cylinders. The service pressure is up to 1800 PSI/124 BAR with a test pressure of 3000 PSI/207 BAR. These cylinders are stamped with required U.S. Department of Transportation and Transport Canada Markings. The 320 Valves are CGA approved, and have a male thread for CO2 Regulators. Note that this supplier is in California so CA residents will be charged tax.

Regulators
After a lot of Googling, the best regulator solution found so far is from Outback Air. Their regulators are set at 150 psi and besides being an excellent value, they don't have the unnecessary gauges which will read the same up until the tank is empty. Static regulator complete with fitting and automatic quick connect coupler included. Outback Air regulator $55.00 Outback Equipped | Outback Air CO2 Systems | "Is Your Rig Outback Equipped?"

Hoses
There are many (many) hose options - here are some:
A1 Coupling (
www.A1Coupling.com) is in Oregon and they claim to provide or have provided hoses and hardware for both Powertank and Outback.
25’ Recoil Air Hose (PURC-14-25R-S-BR-QC) with quick coupler steel, 6-ball and plug steel industrial or automotive style. This is a spiral (coiled) reinforced hose with steel coupler plugs and brass tire chuck. 250 WPSI 4 TO 1 BURST. The hose has reusable fittings with bend restrictors both ends and the hose is reinforced. Available in a variety of colors including red, blue, yellow, and black. Hoses are made in the USA. It’s 1 to 3 days for shipping – most of the time they ship next day.
The coupler plugs are steel and they are most of the time because the SS balls in the couplers will pit a brass plug and will be hard to get apart. If you happen to want a brass 6 ball coupler it will cost about $1.00 more. Dee Evans at A1 Coupling thinks most people would use the industrial style couplers. If they want a universal coupler in brass that will work with either one it’s about $2.00 more.
The contact is Dee Evans and you can call him with questions and to place orders: 1-541-914-0606. The price per hose is $20.95 each.
Other hose options:
25’ Coilhose Pneumatics PU14-25B-B 1/4"ID x 25' Blue Flex Coil Hose With 2-1/4" MPT in neon green only $25.00 (from at the other Raptor website)

Accessories
Deluxe inflator with gauge – 100psi gauge includes rubber gauge guard and storage bag. I recommend using Outback's Deluxe Inflator which enables you to check pressure when inflating so you don't need to switch to a separate pressure gauge and you can let CO2 out if you put in too much pressure.
$55.00 - Outback Equipped | Outback Air CO2 Systems | "Is Your Rig Outback Equipped?"
There are cheaper solutions – usually kits with a variety of cheap stuff in them – available at Lowes and Home Depot and the auto supply stores. There are also more expensive solutions (see Powertank & others).
Tank Boot
Protects the bottom of your tank and has flat sides to keep tank from rolling when lying down.

Mounting Brackets
There are many tank brackets available including some designed to mount the tanks to a roll bar (popular in Jeeps).
Powertank offers a variety of brackets POWERTANK - CO2 Air Systems
Kidde brand #366424 10lb. Dry Chemical Fire Extinguisher Bracket online for $28.00 Kidde 366424 10lb. Dry Chemical Fire Extinguisher Bracket#
A 15# tank bracket can be found here: Amazon.com: Fire Extinguisher Vehicle Bracket - 15HB Heavy Duty - 7.25"-7.5" Dia. Shells: Home Improvement
Here is a real clever solution that will allow users to mount the tank at an angle still allowing the tank to be used (they should not be used lying down) involving a mounting bracket attached to a piece of bent steel:
