The Power Tank 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.
You can get CO2 refills from welding supply shops, fire extinguisher servicing shops, beverage carbonics, and more. It is typically best to call ahead to check pricing and to make sure they can fill your Power Tank onsite, rather than taking it to another facility to be filled offsite. Our smaller Power Shot bottles can be filled at any sporting goods store or paintball shop for a few bucks.
Average cost to fill your Power Tank can be anywhere between $15 to $30 in the US depending on your area and the size of Power Tank you are filling. We are working on compiling a national list of good CO2 suppliers. Please recommend your local CO2 shop to us so we can put them on a searchable map to help out your fellow wheelers. You can email us at email@example.com
All gas cylinders manufactured in the US have stamps which tell a gas supplier what they can be filled with. A Power Tank is stamped for CO2.
CO2 in the Power Tank is stored as a liquid. This is how we can extract a high volume and consistent pressure from the gas. This means more tire fills and consistently high pressure, even as the CO2 runs to nearly empty.
The valves are different. Just like different gas cylinders are stamped for specific gases, the valves themselves have different threads as outlined by the Compressed Gas Association. Power Tank CO2 bottles follow the industry standards of CGA-320 or CGA-302 valves.
CO2 gas used in Power Tanks is collected as a byproduct from other manufacturing processes. Brewing beer (and other alcohol fermentation) and hydrogen fuel production both have CO2 as byproducts that are captured, purified, and sold as food grade CO2, the same CO2 that is used in the soda machine at your favorite restaurant. The CO2 that would normally go directly into the atmosphere, is, instead, recycled for other purposes. Additionally, the amount of CO2 in a Power Tank is very small compared to other sources. According to the EPA, your engine burning one gallon of gasoline produces about 20 lbs of CO2. This is twice the amount of CO2 contained in our most popular 10 lb Power Tank.
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 clump? No and no.
In a word: volume. Having one tank of CO2 is like carrying three tanks of nitrogen. For those of you that need nitrogen for shocks, we have a PRO series N2 compatible regulator as well as N2 shock filling tools. For more information, see our Nitrogen Truths and Myths page.
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 were to get too hot. It is not recommended to store your Power Tank in a vehicle with ambient temperatures above 115 degrees F for extended periods of time.
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. A Power Tank makes no noise which is handy when working around clients and their customers or when working after hours. There are no power lines to run for a Power Tank which would otherwise limit where you can have air. With a myriad of brackets, mounting options, and sizes to choose from, mobility is a huge positive of a Power Tank as well. A hangman bracket allows you to carry air on a scissor lift without worrying about driving over air lines or power lines. Our Power Shot systems allow you to carry about 700 nails worth of air on your belt for the ultimate in speed and maneuverability.
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.
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 a solid state, known as dry ice or gas 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.
Although you can find CO2 tanks pretty easily, you will be hard pressed to find or make a CO2 regulator that does what our Super Flow 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. At most, they are used to operate pneumatic switches and valves, high pressure but low flow rate requirements. The high flow rate is the key to our Super Flow regulators. Our regulators use a proprietary design to provide a very high, constant flow rate which is what enables us 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 Super Flow regulators are well build, compact, and guaranteed to perform to our claims. We back every Super Flow regulator with a limited lifetime warranty, unheard of in the regulator industry.
Unfortunately, the answer is no. We use only top-of-the-line CO2 certified equipment. Scuba tanks are completely different in cylinder and vale design and scuba tanks cannot be used in place of a CO2 tank. Our Super Flow Regulator Kits will not work on scuba tanks.
If you already have your own certified CO2 tank or you would rather swap tanks at your local CO2 shop, we offer Super Flow Regulator Kits which include your choice of COMP or PRO series regulator, our newest powder coated Power Grip Guard Handle, and a 30 ft Super Flex Coiled Hose or a 30 ft Ultra Flex Straight Hose.
The key to regulator performance is its flow rate. The COMP Series HP250 regulator has a maximum flow rate of 40 CFM (cubic feet per minute). The PRO Series XP400 regulator flows at an amazing 45 CFM and is a dual gas regulator for use with both CO2 and N2. Super Flow regulators have the highest flow rate of any other regulators on the market and are guarunteed to never freeze clog.
No. Our Super Flex coiled hoses and Ultra Flex straight hoses are made special for us to be as safe and reliable as possible. The hoses we use can withstand 1000 psi burst pressure at -40F, crucial to deal with the freezing temperatures of CO2. We spec a swivel at both ends that is perfectly usable, even at 400 psi line pressure.
You also lose out on our Super Couplers. The Super Coupler accepts five different plug types which means that any tool you borrow on the trail will fit. It will also fit around your tire valve stem to make tire reseats a breeze. The Super Coupler also features its own on/off bleed valve. When you connect or disconnect a tool, it is always at 0 psi so you're never fighting against pressure to seat a tool in the coupler making life easier and safer.
Accept no substitutes. Our competitors cast their parts out of cheap metals. This makes them brittle and prone to cracking. We machine all of our handle parts out of billet 6061 aluminum because the primary function is to protect your regulator. We have tested this and our Power Grip Guard can protect your regulator from a four foot upside down drop.
Our new patented design also allows you to store your hose and tools in the grip portion, keeping things clean and out of the dirt when you're doing some trail fixes.
No. It will only give you a rough indication of when you are nearing the end of the CO2 because CO2 gives a constant bottle pressure of about 800 psi from full to empty. 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 Tank 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 (e.g. a PT-10 should weigh about 10 lb more than empty). Before you go on a trip you will now be able to weigh your Power Tank and get a good idea of how much CO2 is left in the tank. We offer a very accurate handheld digital Super Scale so you can weigh your tank anywhere, anytime.
First step is to find the source of the leak. The best way to do this is with some soapy water (we use windex in the shop since it has a lower freezing point). Once you have located the leak, please take a picture of your equipment to help us assess the situation. This will give you the fastest possible turnaround.
If your equipment is under warranty, file a warranty claim and someone will reach out to you with the next steps. If it is not in warranty, you can purchase replacement parts here. If you can't find the part you are looking for or need further assistance, go ahead and file a warranty claim anyway and we'll be happy to get you up and running again.
Was your Power Tank completely full when you filled it? Did you weigh it to make sure? A 10 lb Power Tank should weigh 10 lbs more when full than when completely empty. We give you a small spot at the bottom of your tank to write down the empty weight so you're always sure to be getting a full fill.
Have you checked for leaks? CO2 does not lose its charge over time but if the main valve is not closed all the way, you can have a slow leak. This isn't dangerous but will cause you to lose CO2.
If your analog gauge does not reset to zero when there is no pressure, you have probably pegged your gauge by going over the max pressure. This can happen, for instance, when you attach a 60 psi gauge to a tire with 65 psi in it. This is not covered under warranty, but you can purchase replacement gauges easily. Purchase replacement gauges here.
Yes. Your Power Tank can be mounted sideways or even upside down but the tank must be upright or at least at a 30-degree angle while being used. This is because you want the liquid CO2 at the bottom of the tank and the vapor or gas CO2 at the top to flow through the valve and regulator. When used outside of a vehicle, our Floor Bracket (BKT-2400) holds your Power Tank at the perfect 30-degree angle to keep the center of gravity low while keeping the liquid CO2 out of the valves when using air tools in the pit or on a construction site.
Yes and there's no annoying compressor noise or 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 for a clean, simple, worry-free connection between your Power Tank and air lockers. ARBs run so efficiently, you'll hardly use any of your CO2, even after several actuations. If you want a clean competition rock crawler look and performance to match, get the Jet Pak and our air toggle switches.
Monster Valves are large diameter aluminum valve stems designed by Power Tank. They are the fastest deflation devices available and they make inflation faster as well. They are installed in your wheel as a second stem; your original stem is retained to get instant tire pressure readings. They can be installed without needing to remove your tire from your wheel. They have a built-in air lock collar which, when opened, lets air out at a scary fast rate. We use an oversized stem core which means inflation times are cut in half as well. Imagine airing down a 35 inch tire from 30 psi to 10 psi in 15 seconds and then airing back up in 25 seconds. That is a Monster Valve.
Easily and is one more reason to upgrade to a Super Coupler (standard in B and C packages). This is one of the safest and easiest ways to reseat a bead on the trail since you do not need to remove the wheel from the vehicle, hassle with a tire tourniquet, or use any pyrotechnics.
Simply jack up the corner of the vehicle with the unseated tire. Clean the rim bead, straighten the tire, and remove the valve core. Crank your Power Tank to 250 psi and hold the Super Coupler over the valve stem. Open the Super Coupler valve and the high volume of air at once will push the bead back onto the wheel. Replace the stem, lower the vehicle, and use a tire inflator to air back up. It's as easy as that and no singed facial hair. Monster Valves are another quick and easy way to reseat a tire and the procedure is much the same.

There are a lot of factors that come in to play, such as tire size, storage space, air tool use, etc.
For off road vehicles with tires up to 35 inches, a PT10 10 lb Power Tank would probably fit the bill. Larger tires of 36 - 42 inches or higher-pressure tires of 40+ psi would be better suited to running a PT15 15 lb Power Tank.
Where weight and space is a concern on a competition rig or if you're driving a Side by Side or overland vehicle, a PT05 is a good size at 5 lbs of CO2.
Our 20 oz Power Shot systems are great for Side by Sides or passenger cars to use in emergencies.
For the sand crowd, we offer a 20 lb system called the PT20. The PT20 addresses the big need for air in full size trucks (often with trailers) airing down larger high pressure tires for sand traction.
The Power Tank weighs much less than most compressors and doesn't require an extension cord so setup 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 foot 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.
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 Super Couplers. And don't skimp on the quality of your air tools. Cheap air tools use up more air and do less work.
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 foot wall with the air attached to your tool belt.
CO2 is a in a dense liquid state in the bottle. You only want the vapor at the top of your tank running through your equipment. 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 tough enough to last for years. If you change bottle sizes later, no worries. The Floor Bracket can fit tanks from 10 lb. to 20 lb.
The Floor bracket is great for roofers, too. 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 Floor Bracket is available. Just Slide it in, latch it down, and lock it up. Great to mount in your truck bed or on a tool box.
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.
