If there was ever a need for high performance, high pressure air it is here in the RV industry. The RV market is growing and so are the sizes of the coaches and trailers. As these rolling homes get bigger and heavier their tires are required to carry more weight and higher pressures. 110 to 130 PSI tires on newer class A tires are becoming common place although compressed air for even 80-100 PSI trailer tire pressures is sometimes hard to find. The Power Tank RV Series is the simple, portable, quick, and clean solution to this problem. Able to inflate a 22.5” tire from 110 to 120 PSI in approximately 35 seconds from a portable, lightweight (30-40 lbs.) system, a Power Tank makes the chore of tire pressure maintenance a snap. If adjustable air pressure is what you desire then check out the COMP Series or the PRO Series Power Tank systems.

Constructed of heavily padded, ballistic nylon, the SPEED BAG provides protection from bumps and bruises while offering hassle-free mobilty, and large exterior pockets to store your accessories.

If you own an RV motor home, a large travel trailer, or a large towing vehicle you are rolling on high pressure tires.  These tires are made to carry the heavy loads of these large road vehicles and trailers.  For maximum tire safety. tire longevity, and fuel economy it is critical that your hard working high pressure tires are kept properly inflated.  The problem is that some truck and trailer tires need as much as 90 p.s.i. and some newer class A motor home tires now require as much as 135 p.s.i. and compressed air to fill these tires is difficult to find.  If your coach has an air compressor its maximum pressure would have to be at least 30 psi above your maximum tire pressures in order to use it to fill your tires. 

So what options do you have?  Up until now your only options were to carry a large electric compressor like those used by construction contractors if you had a high amp AC outlet.  Or you could stop by a truck stop and hope that they had a working air hose and ready access to it.  If your were lucky you might find an RV service shop and bum air from them.  Of course, if your tires are warm you’d just be guessing at what pressure you should be filling to.

No more.  The RV Power Tank™  is a unique new air system designed specifically to tackle this problem and it does it in a compact, lightweight, and easily portable system.  Advanced Air Systems, Inc. has been designing high performance on-board air systems for the automotive industry since 1997.  We saw the huge need for a high performance air system in the RV industry and in 2002 the first RV Power Tank™  was borne.

You’ll find our RV Power Tank™  system amazingly fast and reliable. You’ll also find the RV Power Tank™  air system easy to use to maintain all of your tires to the correct pressures from your 7 p.s.i.  quad tires to your 135 p.s.i. Class A motorhome tires.

This system is very unique.   The information in our website should have the answers to all of your questions.  If you do not find the answer to your question please email your question to us and we will give the answer.  When you are ready to order the fastest RV tire inflation system available give us a call and we’ll be happy to help you.

RV Power Tank™ System FAQ’s

“What is a RV Power Tank™ and what is it for?”

The RV Power Tank™ is a revolutionary new tool providing high pressure, high flow air in a very portable package.  The primary use of the RV Power Tank™ is to inflate high pressure tires common on RVs, trucks, and trailers quickly and safely.

“Why trucks and RVs?”

Although the RV Power Tank™ can be used to inflate any kind of tires -- from bicycles to passenger cars to tractors, it is more useful for those tires with much higher tire pressure and high volume requirements.  This is because there are fewer means of inflating these kinds of tires quickly -- some as high as 135 p.s.i.  It is also most critical that tire pressures in these hard working large vehicle tires be maintained at proper minimumpressures for safety and longevity.

“How safe is a tank of compressed CO2 in a vehicle?”

The RV Power Tank™ uses liquid CO2 gas as its energy source.  CO2 is a great energy source because CO2 vapor is an inert, non-toxic, non-corrosive, and non-flammable gas.  It stores a higher volume of “air” per tank than any other gas.  Despite its high volume content, CO2 is a relatively low pressure gas, maintaining a tank pressure less than a third that of other common gases like nitrogen or scuba.  Our aluminum tanks are D.O.T. (Dept. of Transportation) approved.    This evaporative process slows the energy release rate meaning that a CO2 tank will not become a high speed rocket like a scuba tank would in the rare event of a valve decapitation. 

“What if the tank is caught in a vehicle fire?  Will it explode?”

No.  There is a built in pressure release cap on the main tank valve which releases the pressure well below the burst pressure of the tank if it got too hot. 

“Is the CO2 safe for my tires and wheels?”

Yes.  Again, CO2, once it leaves the tank, instantly expands to a relatively dry inert vapor gas (non-toxic, non-corrosive, non-flammable).  CO2 is present in the air we breathe and in the carbonated beer and soft drinks that we drink.  In fact, our bodies produce and exhale CO2 into the air.    CO2 gas has no ill effect on rubber, metals, or any other materials.

Will CO2 blow out my tires if they get hot?

No.  The thermal expansion value of CO2 vapor is the same as air. 

“Won’t CO2 leak out of my tires faster than air?”

No.  The CO2 molecule is larger than a nitrogen molecule which is most of what is in air.

“Is the tank refillable?”

Yes.  Liquid CO2 is used throughout the world.  The most common sources of liquid CO2 are welding shops and fire extinguisher service shops.  Other sources are beverage distributors (Coke, Pepsi, Coors, etc.) and paintball supply shops.  The average cost for a 10-15 lb. fill is $12-$15.

“Why CO2 instead of nitrogen?”

CO2 in tires expands and contracts at the same rate as nitrogen (N2) with temperature changes (see “Nitrogen for Tires-Truth or Hype?” ). CO2 makes a great portable air system because it is powerful, easy to get refilled, safe to transport, and needs no electricity, There is no faster way to top off an RV tire than with a Power Tank system. If you wonder why we make our Power Tanks with CO2 tanks instead of nitrogen tanks here’s why: CO2 holds three times more volume of useable energy than N2 in the same tank size so a Power Tank will last far longer between fills. CO2 is a high volume low pressure gas which makes it more practical as a portable air system, a CO2 supplier is easier to find than an N2 supplier, and CO2 can be mixed with N2 or air without compromising the performance of the tire. CO2 is much less expensive than N2.
Most high-end RVers that we deal with are successful and often wealthy individuals with diverse backgrounds and are the most educated and articulate members of any automotive market. If you wanted to read what they think about N2 (nitrogen) for your tires click on the links here and here

“Can I use a Power Tank if I use Equal balancing beads in my tires? I heard CO2 might "condense moisture" in low temperatures and make the beads "clump"”

CO2 vapor does not “condense moisture” as CO2 vapor is dry. I think people assume CO2 is full of moisture because it is called a liquid gas when under pressure. Yes it does have weight but if you shake a half full CO2 tank you will not notice any sloshing like you would if it were like water. Nitrogen vapor, like CO2, is very dry although it too is derived from “liquid” nitrogen …you’ve probably seen liquid nitrogen trucks rolling down the highway? CO2 is so dry, in fact, that some use CO2 air straight out of our Power Tanks to spray enamel and lacquer paints through an airbrush. If you know anything about these paints you know that they would be contaminated with the slightest speck of moisture.

“Why can there be no moisture in the CO2 in my tires if CO2 is called a liquid gas?”

CO2 has the unique characteristic of being able to be stored in a dense amorphous liquid state under pressure (~800 PSI). When CO2 is at atmospheric pressure it goes from a solid (dry ice, -100F) straight to a gas (smoke on top of the Halloween punch bowl) and skips the liquid state. Don’t get CO2 confused with a more familiar chemical called H2O which goes from a solid (+32F) to a liquid and then to a gas. Does H2O condense moisture with temperature changes? Yes. Does CO2? No. Does CO2 cause H2O to condense more with temperature changes and cause Equal to clump? No and no.

“This is a Testimonial regarding the RV Powertank. I had seen several advertisements about the RV Powertank and thought to myself a “great” idea but was weary about putting CO2 in my tires. After talking to my good friend Richard Schoenfeld who happens to be a distributor for Power Tank, I decided to give it a try. I’m here to say that it has been one of the best investments I’ve made, of gadgets for my motor home, mainly for two reasons: First, I carry 110 pounds of pressure in my front tires on my 2003 Dynasty. The best I can get out of the on board compressor is 105 pounds, even with the engine running at fast idle. Presto no problem now with my Powertank. Second, and most important, I do check the air pressure in my tires at least once a week, but in the past if they were 2 to 3 pounds low , rather than going through the process of starting up the engine, crawling underneath to hook up the air hose (which I thought was to much trouble) I just let it slide. Now it’s simple, just take the Powertank out of the bay and bring the pressure up to the recommended level. Presto again, with no hassle. Thanks Richard you made my life a bit simpler plus a whole lot safer.”

“The convenience and functionality of the Powertank system make maintaining the high tire pressures required on Class A motor coaches a snap! I wouldn’t be without my Powertank to keep my tires properly inflated both at home and on the road. I would strongly urge every Class A motor coach owner to consider purchasing the Powertank. Properly inflated tires are critical to highway safety and with the Powertank I now am able to inflate my tires (coach and tow car) anywhere at anytime.”

Back in 2004, I met Kris Fettig at an FMCA Rally. Kris is the Account Executive for the Goodyear RV tire division. That's when I introduced him to our Power Tank. I could sense some skepticism as no one had ever heard of a portable tire inflator that could top off a 22.5" RV tire in seconds. After some testing, Kris became a believer and wrote this nice letter to us and in his last paragraph he hits the nail on the head, " ... make RVing easier and more enjoyable." This is what the Power Tank will do for you. It's time you became a believer.  Give us a call.


Our customer, Mike, owns one of the most beautiful coaches on the open roads. Like most RVer’s he always found tire inflation to be a problem even with his pancake compressor. Now, with his new Power Tank, tire inflations are quick, clean and easy. Here’s Mike’s 45’ Prevost.
