Q: ?Can I run air tools off of a Power TankTM? Is CO2 safe for my tools??
A: Yes and yes. A Power Tank can run any air tool that a shop compressor can run up to a 1/2" drive impact wrench. It's perfect for impact wrenches and nail guns. CO2 vapor is dry, so dry that you can spray paints and varnishes with it straight out of the tank. You?ll want a good quality QR coupler for your hose like our Air Lock Autos or our Tomco Super Couplers. And don?t skimp on the quality of your air tools. Cheap air tools use up more air and do less work.
 

Q: Why do Power Tank's SuperFlow regulators work better than other regulators in tire inflation speed and air tool performance?
A: The key to regulator performance is its flow rate. The COMP Series HPx regulator has a maximum flow rate of 40 CFM (cubic feet per minute). The PRO Series XP300 regulator flows at an amazing 45 CFM and is a dual gas regulator. Superflow regulators have the highest flow rate of any other regulators on the market.
 

Q: ?Can it be mounted sideways??
A: Yes. It can be mounted sideways or even up side down but the tank must be upright or at least at a 30-degree angle while being used. The reason it must be upright during use is because you want the liquid at the bottom of the tank and the vapor at the top coming through the valve and regulator. We highly recommend that your Power TankTM be mounted in a vertical to 45 minimum angle position so it does not need to be removed from its mounting bracket for each use and so it is never mistakenly used in a horizontal position. In an RV, storage sideways in the cargo hold is fine.
 

Q: ?How big is it?? and ?How much does it weigh??
A: P/N Height Wt. Empty Wt. Full PT-5 21? 12 17 lb. PT-10 24? 17 lb. 27 lb. PT-15 30? 21 lb. 36 lb. PT-20 30? 30 lb. 50 lb. (See also the CHARTS AND SPECS page of the website.)
 

Q: ?How much does it cost to refill??
A: Average cost is $12 to$18 (in the US). The cost is similar for all sizes because you are paying more for a service fee than for the gas. The places that fill are fire extinguisher service shops, welding gas supply, beverage carbonics, and paint ball supply (for smaller tanks). Some of our 4x4 dealers also can fill CO2.
 

Q: ?How safe is a tank of compressed CO2 in a vehicle??
A: The Power TankTM uses liquid CO2 gas which is an inert, non-toxic, non-corrosive, non-flammable gas. Our aluminum tanks are D.O.T. (Dept. of Transportation) approved. CO2 goes through a phase change from liquid to vapor as it releases its energy. This evaporative process slows the pressure 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. A Power Tank is as safe as a CO2 fire extinguisher.
 

Q: ?Is the CO2 gas safe for tires??
A: Yes. CO2 vapor is inert (non-toxic, non-corrosive). CO2 vapor is perfectly safe for your tires and wheels. In fact, your body exhales CO2 and you ingest CO2 when you drink a soda or beer.
 

Q: ?Isn?t this just a Scuba tank? Can I use my Scuba tank with your Reg Kit??
A: We get this question a lot. Unfortaunately the answer is no. We use only top-of-the-line CO2 certified equipment. Scuba tanks are completely different in cylinder and valve design and scuba tanks cannot be used in place of a CO2 tank. Our SuperFlow Regulator Kits will not work on scuba tanks.
 

Q: ?What does the Basic Power Tank TM System come with??
A: The basic Power TankTM systems come complete with everything you need to start airing up tires except the gas. This includes the aluminum Luxfer tank, the trademark aluminum Power Grip? guard/handle, a SuperFlex? HP-1100 high pressure low temp. inner braided coiled hose with fittings and air chuck, and one of our three different proprietary SuperFlow C02 regulators. Our aluminum tanks are the lightest on the market for compressed gas, half the weight of steel tanks and aluminum scuba tanks. Our proprietary SuperFlow HPXTM regulators are designed specifically for heavy duty high flow use. The stout Power Grip? guard doubles as a carrying handle although its primary function is to protect the regulator and valve assembly during use and transport. The SuperFlex? coiled hose will not leak, kink, freeze, or crack under the harshest conditions.
 

Q: ?What if I already have my own CO2 tank??
A: If you already have a certified CO2 tank or would rather swap tanks at your local CO2 shop we offer SuperFlow? Regulator Kits which include a SuperFlow? regulator (RV, HPX or XP300), our newest powder coated aluminum Power Grip guard/handle, and our SuperFlex? HP-1100 inner braided coiled hose.
 

Q: ?What if the tank is caught in a vehicle fire? Will it explode??
A: No. There is a built in pressure release cap on all of our main tank valves which releases the pressure well below the burst pressure of the tank if it got too hot.
 

Q: ?What is a SuperFlex? HP-1100 coiled hose??
A: Our SuperFlex? HP-1100 hoses feature a high strength polymer inner braid similar to the material used in synthetic winch ropes. This hose boasts a burst pressure of 1100 psi (@ 72F). Why have such a high burst pressure rating? Safety. At maximum flow rates our hose temperature may drop to sub-zero temperatures. Other hoses would crack or burst at this temperature while the SuperFlex hose stays flexible and maintains a high burst pressure. The RV Series gets a 10' length while the COMP and PRO Series systems get 25' hoses.
 

Q: ?Why can?t I just make my own Power Tank TMCO2 system? What?s the difference??
A: Although you can find CO2 tanks around you will be hard pressed to find or make a CO2 regulator that does what our SuperFlow regulators do. This is because common gas regulators that you would find at a welding or restaurant supply store are not designed to provide a high-pressure output AND, MORE IMPORTANTLY, A HIGH FLOW RATE. They are designed for low pressures and low flow rates. At the most they are used to operate pneumatic switches and valves ? higher pressure but again low flow rate requirements. The high flow rate is the key to our SuperFlow HPXTM regulators. Our regulators use a proprietary design to provide a very high constant flow rate which is what enables it to run large air tools and inflate multiple tires at a high rate of speed. Normal regulators will quickly ?freeze clog? and often destroy internal parts even at moderate flow rates due to CO2's freezing temperatures. Our SuperFlow regulators are compact, well built, and guaranteed to perform to our claims. We back every SuperFlow regulator with a limited lifetime warranty. This is unheard of in the regulator industry. Finally, we protect the regulator assembly against damage with our stout powdercoated aluminum Power Grip? guard/handle.
 

Q: ?Why CO2 instead of Nitrogen??
A: "Volume". CO2 will give you three times the energy of Nitrogen in a given tank size. Having one tank of CO2 is like carrying three tanks of nitrogen. This makes it more economical and means that you?ll have the power when you need it all in one small tank.
 

Q: ?Will CO2 leak out of my tires faster than air??
A: No. The CO2 molecule is larger than a nitrogen molecule which is 78% of air.
 

Q: ?Which Power Tank system do I need? What would you recommend?"
A: Offroad / Sand / Desert / 4x4 / Trail - If this is for an offroad vehicle I recommend the PT-10 COMP Series for most vehicles. If you have up to 36? tires a PT-10 will usually fit the bill. The PT-15, also a popular size, is for rigs running larger tires (36? to 42?) and/or with higher-pressure needs (40+ PSI). We also have a PT-5 system, usually for competition vehicles, Rhinos or sand cars where weight and space are a concern. For the sand crowd we offer a 20 lb. system. The PT20 addresses the need for huge air in full size trucks (often with trailers) airing down larger high pressure tires for sand traction. If you need nitrogen pressure for shock maintenance look at the PRO Series XP300 Regulator Upgrade over the COMP Series HPX Regulator.
 

Q: ?Can I run air lockers with a Power TankTM??
A: Yes and there?s no annoying compressor noise. There?s no waiting for the compressor to pressure up. As a precaution you MUST run a pressure release valve before the solenoid set to a maximum of 100 psi. To save time and headache we recommend using our ARB install kit (#ARB-2010) for a clean, simple, worry-free connection between your Power TankTM and your air locker. And ARB?s run so efficiently you?ll hardly use any of your CO2 even after several activations. If you want a clean competition rockcrawler look and performance get the JET PAK ? and our air toggle switches.
 

Q: ?Why CO2 instead of Nitrogen??
A: "Volume". Having one tank of CO2 is like carrying three tanks of nitrogen. For those of you that need nitrogen for shocks or critical tire pressures we do have the PRO Series N2 compatible Superflow Regulator as well as N2 shock filling tools.
 

Q: ?Can the Power TankTM seat tire beads??
A: ?Hellyeah? and here?s another reason to get a quick release coupler for your hose. One of the advantages of the awesome power of the Power TankTM is its ability to quickly and easily seat tire beads without the need to remove the wheel from the vehicle or hassle with a tire tourniquet. All you have to do is lift the corner of your vehicle with the unbeaded tire. Get the tire straight and clean the rim bead. Remove the core of the wheel stem. Set the outlet pressure of the Power TankTM up to 200 psi. While pulling the tire out towards the bead of the rim push the end of the hose quick release coupler straight over the stem giving the tire a quick blast of air. The sudden rush of air into the tire will push the sides of the tire out and onto the sides of the rim. Hold it there until the tire has ?popped? over the rim bead. Remove the hose from the stem and replace the stem core. Reset the tire pressure, lower the jack, and you?re on your way. No cinged facial hair! Monster ValvesTM also make tire reseating easier.
 

Q: ?What are Monster Valves???
A: Monster valves? (P/N MON-8200) are large diameter aluminum valve stems designed by Power TankTM. They are the fastest deflation devices available and they even make inflations faster. They are installed in your wheel as a second stem and are installed without having to dismount your tire from the rim like other stems. They have a built-in ?Air Lock? collar which, when opened up, lets air out at a scary fast rate. And because of its oversized core size inflation times are actually cut in half. Imagine airing down a 35? tire from 30 psi to 10 psi in 15 seconds and then airing back up in 25 seconds.
 

Q: ?Does the SuperFlow? regulator gauge tell me how much CO2 I have left??
A: No. It will only give you a rough indication of when you are nearing the end of the CO2. The only way to get an accurate read on how much CO2 you have left is to weight your tank. What we recommend is that you weigh your Power TankTM assembly on an accurate scale while it is empty. Record this empty weight (write it down with a permanent marker on the tank weight box on the lower label). Once the tank is filled check to make sure you got an accurate fill (ie. a PT-10 should weigh exactly 10 lb. more than empty). Before you go on a trip you will now be able to weigh your Power TankTM and get a good idea of how much CO2 is left in the tank. We offer a very accurate handheld digital Super Scale (P/N CO2-2050) so you can weigh your tank anywhere, anytime.
 

Q: ?Which Power Tank system do I need? What would you recommend?"

Q: ?Which Power Tank system do I need? What would you recommend?"
A: RV / Motorhome - The RV Series Power Tank was designed specifically for RVer's who need to top off their relatively large, high pressure tires. The RV Series with its special accessory packages are designed to meet specific RV tire inflation needs. For high pressure RV tires up to 19" rim sizes will do well with the 10 lb. size. Those of you with 22.5" - 24.5" wheels and tires can go with either the 10 lb. size or the 15 lb. size. If you are a full timer go with the 15 lb. system. If carry weight is a concern you may want to go with the 10 lb. system. (Remember, 10 lb. and 15 lb. simply refers to the amount of CO2 that the tank holds. The RV10 system weighs 28 lb. full and the RV15 system weighs 38 lb. full.) For top performance and features tht make it easy to use go with our best seller, the Platinum Package.
 

Q: 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?.
A: CO2 vapor does not ?condense moisture? as CO2 vapor is dry. Some people assume CO2 is full of moisture because it is called a "liquid" gas when under pressure. Once released from the tank to low pressure like tire pressures, however, CO2 exists in two states: solid (dry ice) or vapor. Unlike water, CO2 has no liquid moisture state. CO2 is so dry, in fact, that it is used straight from the tank to push enamel and lacquer paints through paint guns. You will have no problems with clumping of Equal balancing beads from using CO2 in your tires.
 

Q: How can there be no moisture in the CO2 in my tires if CO2 is called a liquid gas?
A: 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 into 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.
 

Q: ?Why Would I want a Power Tank when I already have a nice compressor??
A: There will be jobs where a compressor will still be better like in the initial framing stages. However, after the major framing is complete a Power Tank may help you save time and effort making you more productive. And since a Power Tank makes no noise this can come in handy when working around clients and their customers or when working after hours. Because it is not electric you have no cords limiting where you can have air. Fencers will appreciate that.
 

Q: ?How can a Power Tank make my job easier??
A: The Power Tank weighs much less than most compressors and doesn?t require an extension cord so set up is easier and quicker. To avoid the compressor noise the compressor is often stuck in an empty room or outside and an extra long air hose is run to the work area. With a Power Tank you can bring it right into the work area and reach every corner with our 30? light weight hose. When it?s time to pack up and leave a Power Tank and hose may be half the weight of a compressor, extension cords, and hoses. This is key to saving time and energy in a pick up job where you may only need to shoot a few dozen nails and then leave.
 

Q: ?Is this system safe for my air tools like my nail guns and impact wrenches??
A: Yes. CO2 vapor is an inert and dry gas and is cleaner and drier than air from most compressors. Power Tank regulators are limited to a safe maximum pressure for air tools and all have built-in pressure release mechanisms in case of pressure seat malfunction.
 

Q: ?Do I have to worry about the moisture of CO2 in my air tools??
A: No. Even though many think of CO2 as a gas full of moisture because it is called a ?liquid? gas it is only in this dense ?liquid? state under pressure. Once it is in low pressure it can only be in either solid state, dry ice, or vapor state. CO2 introduces no moisture into your air tools. In fact, CO2 vapor is used to push all types of paint out of sprayers with no in-line drier required.
 

Q: Where do I get my tanks and bottles refilled?
A: The tanks (5 lb. on up) are filled at fire extinguisher service shops, welding gas suppliers, or beverage carbonics. The small bottles can be filled at a paintball supply shop, some fire extinguisher shops, or by yourself. We sell simple equipment that would allow you to refill your small bottles off of a 10-35 lb. tank at the job site, at the company, or in your garage. There is a wide range of prices for CO2 so shop around.
 

Q: ?How is the Sidearm System used??
A: The uniqueness of the Sidearm System is its compactness. However, don?t mistake this as a low performance air system. You can actually operate a ? impact wrench or shoot 8d nails off of this tiny bottle. You can do anything with a Sidearm that you can do with a Power Tank or compressor but with more mobility. This air system is perfect for the small roof jobs, quick pick up jobs, or those jobs where you need to cover a lot of ground fast. It is also the tool that every finishing carpenter needs to have. Features of the Sidearm Kit: A special Sidearm Regulator controls the pressure from 0-160 PSI. Two 20 oz. bottles to start you off with. The Sidearm holster can slide onto a 3? belt or clipped onto your pocket when you?re not wearing a tool belt. Metal rivets hold the nylon flaps together and an extra layer of webbing is added at the top of the belt loop wear surface. Pencil pockets on the side. Strap with snap to hold bottle in place. Straight Jacket Sleeve with clip allows you carry a full spare bottle up a ladder. A 10? coiled SuperFlex hose is lightweight and durable and a stainless steel Power Wrench makes your life easier. High quality fittings throughout and a custom carry case to put everything in.
 

Q: ?Can something as small as the Sidearm actually do anything for me??
A: Absolutely! The Sidearm has the power to fully sink 8d nails and the volume to install over 1000 feet of trim. If you?re a finisher imagine installing crown molding and kick board in a 2000 sq. ft. house with the air attached to your tool belt. For custom builders, imagine framing a new 15? wall with the air attached to your tool belt.
 

Q: ?Does the SuperFlow? regulator gauge tell me how much CO2 I have left??
A: No. It will only give you a rough indication of when you are nearing the end of the CO2. The only way to get an accurate read on how much CO2 you have left is to weigh your tank. What we recommend is that you weigh your Power TankTM assembly on an accurate scale while it is empty. Record this empty weight (write it down with a permanent marker on the tank weight box on the lower label). Once the tank is filled check to make sure you got an accurate fill (ie. a PT-10 should weigh exactly 10 lb. more than empty). Before you go on a job you will now be able to weigh your Power TankTM and get a good idea of how much CO2 is left in the tank. We offer a very accurate handheld digital Super Scale (P/N CO2-2050) so you can weigh your tank anywhere, anytime.
 

Q: ?Isn?t a CO2 bottle like a bomb if heated or dropped??
A: No. We use DOT (dept. of transportation) and CGA (Compressed Gas Association) approved bottles and valves. Pressure relief valves are installed on every one of our bottles in case of over charges or exposure to heat. The bottles are rated for pressures well above the pressure relief valve failure pressures. And CO2 releases its contents in a much slower rate than other types of gases that are stored as compressed vapors (nitrogen, scuba, HPA). Our 20 oz. bottles are similar to those used in the paintball field and have the newest safety features.
 

Q: ?What is the significance of the Wedge Bracket (AKA Floor Bracket)??
A: Because CO2 is in a dense state, ?liquid?, in the bottle and you must make sure that it is not dispensed through the regulator. You can stand it up vertically but the bottle can tip over and damage a nice floor. The Wedge Bracket sets the Power Tank low for maximum stability yet tilts the head up just enough to allow the vapor to be dispensed from the valve. Large rubber feet protect the surface of the floor. All aluminum construction keeps the bracket light yet is designed to last for years. If you change bottle sizes later, no worries. The floor bracket can fit tanks from 10 lb. to 20 lb. And the Wedge Bracket lends a hand to roofers. Just hook it to a nail through one of the large holes in the bracket floor. For added security and convenience, an optional Base Mount for the Wedge Bracket is available. Just Slide it in, latch it down, and lock it up.
 

Q: ?What?s the Hangman Bracket used for??
A: The design of the Hangman Bracket came about after watching some guys working with their Power Tank on a scissor lift inside a grocery store. Two guys on this lift had to work around their Power Tank sitting on the floor careful not to drop it over the edge or get tangled up in the hose. With their help I designed a bracket that enabled the Power Tank to safely hang on the outside of the often crowded cage. This really freed up their movement and safely secured the Power Tank to the rails. Also hooks over a 2x4 and a ladder cross-brace.
 

Q: Last Word
A: When Power Tanks came out in the off road industry over ten years ago it was a similar landscape to the construction market. Compressed air was widely used and compressors were the only game in town. Now, Power Tanks are used by almost every top offroad competitor either on their rig or in their pits. The construction industry is also competitive. The faster you can finish a job the more valuable you become. That?s what our Power Tank Construction Series is all about. Giving you the tools to make your job faster and easier.
