Frequently Asked Questions About The Power Tank

 

What Is A Power Tank And Why Do I Need One?

The Power Tank is a product that addresses need of onboard air on an offroad vehicle. Power Tank consists of an aluminum cylinder of pressurized CO2 that is stored in a liquid state but released as a vapor through a special SuperFlow regulator. Power Tank specially designed the SuperFlow regulator for this type of use. Power Tank can air up tires, run air tools, etc. on the trail, the side of the road, or even in the garage. Power Tank is fast, affordable, and simple to use. Power Tank is lightweight, portable, and reliable. Power Tank is also by far the fastest way to air up tires after trail rides.

 

What Makes Power Tank The Best Overall Option For Onboard Air?

Power Tank has the power and speed of an engine-driven compressor and the portability and lower cost of most 12v air compressors. Very few air compressors can match both the flow rate and high pressure of the Power Tank. The Power Tank's SuperFlow Regulator is adjustable from 0 to more than 200 psi and the high amount of airflow generated by a fully open regulator is much greater than that achieved by almost all vehicle-mounted air compressors. Power Tank can air up a 33" tire in less than one minute, remove a stuck lug nut in two seconds using a 1/2" impact wrench, and quickly reseat a tire while the wheel is still on the vehicle. Unlike an air compressor, Power Tank is hand portable so you can take it to a friend who is difficult to get to on the trail. No other air system can do all of this - at any price.

 

How Does Power Tank Compare To A Five-Gallon Air Tank?

We've all seen 4X4's carrying air tanks with compressed air to fill flat tires. The truth is, these bulky tanks store very little energy. A PT-10 Power Tank is less than half the size of a five-gallon air tank, yet it holds 20 times the energy. For example, a five-gallon air tank pressurized to 125 psi will air up two 33X12.5" tires from 10 to 20 psi. The PT-10 will air up 40 of the same tires. The PT-15 will air up a remarkable 60 tires. Furthermore, each "air up" will take only approximately 30 seconds with the Power Tank.

How Much Does A Power Tank Cost?

The typical Power Tank system (a PT-10B basic system + a PB-10 mounting bracket) is under $400. No comparably priced 12-volt compressor can touch the performance, versatility, or speed of the Power Tank system. For complete prices of all the Power Tank systems and the available accessories, see the Power Tank Product Page.

 

What Does The Basic Power Tank System Come With?

The PT-10 and the PT-15 systems include everything you need to start airing up tires. This includes the Power Cylinder, Power Handle, 25' Power Hose with fittings and air chuck, and the SuperFlow Regulator. The Power Cylinder is the lightest on the market for compressed gas--half the weight of steel tanks and aluminum scuba tanks. The SuperFlow Regulator is proprietary to Power Tank and was designed specifically for industrial and vehicular use. The stout Power Handle doubles as a carrying handle a guard to protect the SuperFlow Regulator and valve assembly during use and transport. The polyurethane Power Hose will not leak, kink, freeze, or crack under the harshest conditions.

 

Why Can't I Just Make My Own CO2 System And Save Money?

Although you can find CO2 tanks around you will be hard pressed to find or make a CO2 regulator that does what the SuperFlow Regulator does. This is because other CO2 regulators that one finds at welding or restaurant supply stores are not designed to provide both high pressure as well as a high flow. Rather, the commonly available regulators are designed to provide a shielding gas in welding or push beer and soda from a tap, both low-flow applications. At most such regulators are used to operate pneumatic switches and valves - higher pressure but again, low-flow applications. The high-flow capability is the key to the Power Tank's SuperFlow Regulator. Unlike commonly available regulators, the SuperFlow regulator is designed to provide a high flow rate, which is what enables Power Tank to inflate tires at a high rate of speed and run air tools at their recommended pressures.

Frozen Regulator

Normal CO2 regulators will "freeze clog" and sometimes destroy internal parts even at moderate flow rates. The SuperFlow Regulators are compact, well built, and guaranteed to perform all of Power Tank's claims.

The SuperFlow Regulator is also protected by the Power Handle, which encompasses the SuperFlow Regulator. Readily available regulators usually sit atop their tanks and are exposed to the hazards of the trail.

 

What If I Already Have My Own CO2 Tank?

If you already have a CO2 tank or would rather swap tanks at your local CO2 shop, you can purchase Power Tank's SuperFlow Regulator Kit. The Regulator Kit includes a SuperFlow Regulator, Power Handle, and the Power Hose kit for $210. Just attach these items to your CO2 tank and you will have the power and utility of a Power Tank.

 

How many tires can I inflate with my Power Tank and how long does it take?

The amount of tires you can air up necessarily depends on the pressure to which you air up your tires. The tables below show give the applicable numbers for various tire sizes. If your particular tire size is not listed, you can estimate your applicable number by looking at the tire size that most closely corresponds to yours.

Power Tank is one of the fastest methods for airing up your tires. Onboard air compressors don't even come close to the speed of a Power Tank. Airing up can be a chore with other methods especially in cold and wet weather. With Power Tank, airing up tires is quick and easy usually taking less than four minutes to air up all four tires. An important thing to remember with Power Tank compared to other CO2 tanks is that Power Tank's SuperFlow Regulator does not freeze as readily as standard regulators. Standard regulators are not designed for high-flow applications and freeze solid much more easily than the SuperFlow Regulator. Accordingly, air up times are substantially larger with generic CO2 tanks than with Power Tank.

Why Does The Power Tank Use CO2 Instead Of Nitrogen?

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.

 

What Is the Warranty On A Power Tank?

Power Tank is the most reliable onboard air system since there is essentially nothing to break down, burn up, or seize. Power Tank requires minimal maintenance (just keep it clean) and as long as you follow the simple operating instructions you will get years of trouble-free use from your Power Tank. Advanced Air Systems covers each Power Tank with a one-year free replacement or repair of any defective component of the Power Tank. After that, Advanced Air Systems offers a lifetime free-labor repair policy on the SuperFlow Regulator as long as the repair is possible and the customer is responsible only for the shipping and parts costs.

What Size Power Tank Do I Need?

We recommend the PT-10 for most vehicles from Samurai's to Broncos for its optimum size and energy volume, as well as a Power Bracket.

The PT-15 is for rigs running larger tires (36" to 44"), vehicle support trailers, or for those who just want to carry more air for running air tools. It really does come down to personal preference.

 

Does Pressure Drop As The Power Cylinder Depletes?

The outlet pressure is adjustable at the SuperFlow regulator from 0 to more than 200 psi constant pressure. Unlike with air tanks, the outlet pressure of the Power Tank does not drop as the Power Cylinder depletes with use. So long as there is liquefied CO2 in the Power Cylinder, the output pressure will remain at your desired setting.

 

Do The High Pressure Gauges Tell Me How Much CO2 I Have Left?

No. The gauges on the SuperFlow regulator will give an accurate reading of the pressures inside the tank and the regulator, but only 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 in your Power Cylinder is to go by weight. What we recommend you do is weigh your Power Tank assembly on your bathroom scale while it is still empty. Record the weight from your scale. Once the tank is filled add 10 lbs. to the empty weight (add 15 lbs. for the PT-15) and that is the weight of your full Power Tank. Before you go on a trip, weigh your Power Tank and get a good idea of how much CO2 is left in the Power Cylinder.

 

How Does One Get The Power Tank Filled?

The Power Cylinders can be refilled at most welding supply shops, fire extinguisher equipment shops, and commercial beverage suppliers. Simply remove the Power Handle and SuperFlow Regulator and take the Power Cylinder to these shops and ask for a CO2 refill. They will know what to do. Make sure that you get the same tank back and not an exchanged tank. Some shops have their own CO2 pumps and will fill your tank while you wait. Those that don't need to send it out to get filled and returned. Allow 2 to 3 days turnaround time if this is the case.

It is a good idea to weigh your empty cylinder (you can use a bathroom scale) beforehand and then check the weight of the full cylinder to ensure that the shop did not underfill or overfill your cylinder (i.e. A full PT-10 should be 10 lbs. heavier than when it was empty.)

We highly recommend you fit a Tank Boot to your Power Cylinder. The people at the welding and industrial gas shops are accustomed to dealing with old and mangled tanks and may treat your beautiful Power Cylinder poorly. Fitting a Tank Boot will prevent the bottom of your Power Cylinder from getting dented, chipped, and scratched.

The Tank Boot also features an octagonal collar that will prevent your Power Cylinder from rolling in case it falls on its side.

 

How Much Does It Cost To Refill A Power Cylinder?

Average cost is $15 to $20. The cost is usually similar for all three sizes of the Power Tank because what you are usually paying for is not so much the gas but for the set-up fee. Some shops, however, charge by the weight of the charge.

 

Can The Power Tank Be Mounted Sideways?

Yes. One can mount the Power Tank sideways or even up side down.

The Power Brackets are drilled on the back and bottom faces to permit as many different mounting options as possible. However, the Power Cylinder must be upright or at least at a 30-degree upright angle while being used. The reason the Power Cylinder must be upright during use is because you want the liquid at the bottom and the vapor at the top coming through the regulator. We recommend that you mount your Power Tank in a vertical fashion so that it does not need to be removed from the Power Bracket during use.

 

Can I Run ARB Air Lockers With A Power Tank?

Yes. Many people who want more reliability from their ARB Air Lockers have converted to an entirely pneumatic system. Entirely pneumatic systems are quieter, quicker, and more reliable than using the ARB Air Compressor, electric switches, and solenoids to operate to ARB Lockers. The vast majority of the troubles associated with the ARB Air Locker originate in the electrical wiring, the ARB Air Compressor, or the electric switches. Bypassing all of the electrical circuitry and converting to an entirely pneumatic control of the ARB Locker results in an awesome combination of the versatility of the ARB Air Locker with substantially greater reliability and almost unlimited capacity. Even a single PT-10 Power Cylinder holds enough CO2 to power thousands of ARB Locker activations.

To convert your ARB Lockers to a completely pneumatic system, set the SuperFlow Regulator to the recommended 100 psi pressure and run an air hose from the SuperFlow Regulator to a pneumatic switch. Run an air hose from the pneumatic switch to the ARB Lockers. You must also run a pressure release valve inline to prevent accidental overpressurization of the ARB O-rings. Power Tank offers an ARB connection kit which includes a 100 psi pressure release valve and we recommend an 80 psi reg. setting. It is very easy to forget to turn down the pressure after using the Power Tank for a repair. The inline pressure relief valve is insurance against overpressurizing the ARB system.

 

Is The Power Tank Safe?

Yes. All of the Power Tank's components are heavy duty and built to maximize safety. Every component of each Power Tank is brand new and DOT Approved.

Power Tank's 6061-T6 aluminum Power Cylinders are overbuilt for pressures substantially higher than the Power Tank's standard operating pressure. Each Power Cylinder's service pressure rating is 1800 psi and the burst pressure of the tank is 4000 psi, yet the normal cylinder pressure range for CO2 is only 500 to 1000 psi depending on material level and the ambient temperature. In other words, the Power Cylinder is designed to handle working loads of psi more than the maximum working pressure of CO2. The Power Tank's standard operating pressures are nowhere close to the maximum 4000 psi level of the Power Cylinder.

Each Power Cylinder is equipped with a safety "pop-off" valve built into the main valve assembly. This safety valve sits opposite the regulator mount and is preset to release pressure if the contents of the Power Cylinder should ever reach 3000 psi (e.g., during a fire or accidental overfill). Thus, the pop-off valve will release the contents of the Power Cylinder well before the Power Cylinder's bursting point.

The adjustable SuperFlow regulator limits the maximum outlet pressure to over 200 psi. No matter what the pressure is inside the Power Cylinder, the SuperFlow regulator will limit the output pressure of the Power Tank system to a maximum of about 220 psi.

The Power Handle at the top of the Power Tank doubles as a guard to protect the SuperFlow regulator and valve from getting knocked or damaged. The Power Handle is made of solid 6061-T6 rod and billet and secured to the cylinder with 3/8" stainless steel bolts.

 

Isn't A CO2 Tank Like A Bomb In My Vehicle?

No. Unlike nitrogen or SCUBA tanks that hold 100% compressed vapor energy, liquid CO2 goes through an evaporation process before it becomes pressurized vapor energy. Thus, CO2 maintains a much lower tank pressure and releases in a slower manner. This means if the valve were knocked off a nitrogen or scuba tank, the tank would become a gas rocket. If the Power Tank's valve were knocked off, the sudden release of pressure is still dangerous, but far less so than a SCUBA tank.

 

Because Power Tank Is Relatively Safe, Can I Ignore Safety Rules While Using My Power Tank?

Absolutely not. Whenever handling high-pressure equipment, you must take precautions and practice common sense. Adhere to the following safety rules:

 

Will The Power Tank Run Air Tools?

Yes, and the ability to run air tools efficiently and properly is what separates the Power Tank from most air compressors. Try that with most onboard air compressors and see what kind of results you get.

Having the capability to power air tools on your vehicle is more necessary than most people think. No matter how careful you are, you will eventually break something on the trail. When you do break something, having air tools available will greatly facilitate repairs. Here, Axel Haakonsen lends the use of his PT-15 to Sue and Neil Buchelt on their Moab 2003 trip. Sue's rear differential gave and they used the Power Tank to power a 1/2" impact wrench to remove the third member.

One reason the Power Tank shines over its copycats is the Power Tank's flexibility. The Power Tank's SuperFlow Regulator is both a high-flow and high-pressure system. All of the Power Tank's copycats are either high-flow or high-pressure, but not both. Good quality air tools require high flow but not high pressure. The Power Tank can accommodate these quality air tools.

The Power Tank is also especially suited to air tools because it is adjustable. Many copycat systems use a fixed-out regulator that is either too high or too low for all applications. One copycat system uses a 125 psi regulator to suit all needs. This is a mysterious choice, as 125 psi is too high for quality air tools, but too low for quick inflation of tires. 125 psi is also unnecessarily high to operate ARB Air Lockers but too low to reseat a tire properly.

Not so with the Power Tank. The user can adjust his Power Tank to deliver 100 psi for his ARB Air Lockers. He can adjust his Power Tank to deliver 90 psi for his quality air tools while maintaining the high flow of air that air tools demand without freezing the SuperFlow Regulator. Or he can adjust his Power Tank to the absolute maximum for reseating a tire with a broken bead. Only the Power Tank offers these options.

The Power Tank's air hose is suited for air tool use on the vehicle. The Power Hose is long enough to reach the vehicle's extremities, even when the Power Tank is mounted inside the vehicle's cargo area. If the user needs to work on another vehicle that is out of reach, it is a simple matter to detach the Power Tank from the Power Bracket and carry the system to another location.

The Power Tank comes with a female air chuck that threads onto the end of the Power Hose.

To facilitate air tool use, we recommend that once you receive your Power Tank you invest in a quick-detach coupler for the end of the Power Hose that matches the type of plug used on your air tools. If you fit plugs to your air tools, you will be able to change from the supplied air chuck to your air tools quickly and easily without having to thread and unthread your air tools.

There are several different types of plugs in common use. We prefer to use the Industrial Interchange (Type 15)pattern, pictured above, because that is the most common pattern and also type of fitting the Power Tank comes with for its SuperFlow Regulator and air hose. This pattern is also featured on the line of Staun Massojet Air And Water Gun. Our favorite Industrial Interchange plug is the Amflo Industrial Interchange Plug, an all-brass design.

For couplers, we do have preferences as well. Obviously, if your plugs are the Industrial Interchange type, then your couplers should also be an Industrial Interchange type. Avoid the "universal" couplers as they do not seal as well and leak air. Furthermore, not all Industrial Interchange couplers are created equal. We prefer the Coilhose Pneumatics Six-Ball Coupler, partly because of its slim design.

This coupler features six ball bearings instead of the usual three or four. The greater number of ball bearings means that this coupler will hold the coupler more securely and seal better.

pt001 023_.jpg

An indispensable air tool for the Power Tank is the Heavy-Duty Inflator, also from Power Tank. On our personal Power Tanks, we have dispensed with the air chuck for our normal use and replaced it with the Heavy-Duty Inflator.

pt001 025_.jpg

The Heavy-Duty Inflator features a very legible dial gauge that reads pressures from 0-60 psi.

pt001 011_.jpg

The dial is now larger than ever before for even greater legibility.

pt001 018_.jpg

The dial's body is covered with black rubber to protect the dial from knocks and scrapes.

The Heavy-Duty Inflator's dial gauge is much more legible in low-light conditions than stick gauges.

pt001 031_.jpg

The Heavy-Duty Inflator's air chuck clips onto the valve stem.

There is no need to hold the chuck against the tip of the tire's valve stem. Simply clip the chuck onto the valve stem and depress the thumb lever to inflate. The Heavy-Duty Inflator's dial is very legible and permits one to see pressure readings even at a glance.

There is no need to remove the Power Tank from its mount, and the Power Hose and Heavy-Duty Inflator are more than long enough to reach all four wheels on your vehicle.

Even long-wheelbase vehicles have no problem with the reach of the Power Hose. This photo depicts a Range Rover Classic LWB with the tank mounted to driver-side rear corner. The owner is filling is passenger front tire, yet there is plenty of stretch left in the Power Hose.

pt001 027_.jpg

The latest version of the Heavy-Duty Inflator features a swivel at the end of the air hose that permits the clip-on air chuck to swing freely. This prevents twisting and kinking of the air hose.

One can also use the Heavy-Duty Inflator to air down tires. We much prefer using the Staun Tire Deflators to air down our tires, but there are times when one wants merely to fine tune air pressures or go lower than the level to which one's Stauns are preset. For such uses, the Heavy-Duty Inflator is ideal. The Heavy-Duty Inflator is a very handy air tool that we highly recommend for all Power Tank users.

Like all standard air tools, the Heavy-Duty Inflator accepts the standardized 1/4" NPT threaded attachments.

Simply seal the plug's threads with Teflon tape or thread sealant and then thread on the plug.

Fitting a plug to the Heavy-Duty Inflator is very easy. Again, we have standardized the Industrial Interchange type for our own use.

With the plug threaded onto the Heavy-Duty Inflator, the unit can be attached and detached instantly.

Once secured to the Power Hose, the Heavy-Duty Inflator is ready to inflate your tires.

Fitting an Industrial Interchange plug to the Heavy-Duty Inflator will also permit direct fitment to the SuperFlow Regulator's Industrial Interchange coupler in the unlikely event the Power Hose fails. Even with no hose, you will still be able to air up your tires.

Most of the Power Tank's use will be with the Heavy-Duty Inflator. There are, however, several other air tools that we regularly use with our Power Tanks. Thus, the quick-detach coupler becomes more necessity than convenience.

While we do not use the air chucks on a regular basis, we have fitted our air chucks with plugs and hold them in our tool kits in just case our Heavy-Duty Inflators malfunction, however unlikely that may be. The air chuck and plug take so little space that they are not burdensome to store or carry, and having a backup is always a good thing.

With the plug fitted, the air chuck attaches and detaches just as easily as the other air tools.

Another handy air tool for the Power Tank is a blow gun, like this Blue-Point model. With a blow gun, one can blow dry a wet part, blow off dust prior to final cleaning, etc. The uses are almost unlimited.

The blow gun attaches and detaches so easily and takes so little room, there is no reason not to have one handy for your Power Tank.

DSC08498_.jpg

The Amflo Flexible-Tip Blow Gun is ideal for inflating balloons or for reaching into tight spaces into which a standard blow gun will not fit. This unit is not intended to replace standard blow gun but rather supplement the standard blow gun.

DSC08503_.jpg

There is no operating lever on this blow gun. To exhaust compressed air, simply depress the rubber nozzle sideways.

DSC08499_.jpg

Like all standard portable air tools, the Flexible-Tip Blow Gun features a female 1/4" NPT thread and can be fitted with the Amflo Male-Threaded Industrial Interchange Plug.

DSC08501_.jpg

Fitting the Plug permits one to use the Flexible-Tip Blow Gun with the Coilhose Pneumatics Six-Ball Coupler.

DSC08520_.jpg

Here is a few of some of our air tools for exhausting compressed air. Left to right are the Power Tank Heavy-Duty Inflator, Blue-Point YA1052 Telescoping Blow Gun, Blue-Point JT13 Blow Gun, Amflo Flexible-Tip Blow Gun, and Schrader air chuck that comes standard with every Power Tank. All of these tools have been fitted with the Amflo Male-Threaded Industrial Interchange Plug and thus are compatible with all of our air hoses (which are all fitted with Coilhose Pneumatics Six-Ball Couplers). It is very easy to swap tools back and forth using this system of fittings and connectors.

In addition to operating inflation and blow guns, the Power Tank will also operate air tools. This FAR750 1/2" Drive Air Ratchet from Snap-on requires only 90 psi and 3.8 CFM of air flow, well within the capabilities of the Power Tank.

The grip has an ergonomic shape and the trigger is the button-type so that the hand can more securely grip the air ratchet with the non-index fingers during use or nonuse. There is no need to hold the unit gingerly as with other lever-operated air ratchets.

One can also operate the trigger with the thumb in tight spots when the air ratchet has to be directed sideways. This is a very nice unit.

The exhaust port for the FAR750 is at the very rear. This is a very nice feature as the compressed air is blown away from the user and the usually dirty work area.

The FAR750 has the standard 1/4" NPT threads and accepts the same Amflo Industrial Interchange Plug.

Just attach the air ratchet to your Power Hose and you're ready to wrench.

Need more power than the FAR750 can deliver? No problem. This Snap-on IM6100 1/2" Drive Impact Wrench delivers 550 ft. lbs. of torque going forward and 625 ft. lbs. Of torque in reverse.

The IM6100 runs at 90 psi pressure and draws 4.3 CFM of air flow. This is very little air draw for such a powerful impact wrench. The relatively low air draw of the IM6100 is well suited for the Power Tank, which has a finite capacity.

The IM6100's handle features an ergonomic shape with slight palm swells. The entire handle and trigger are coated with rubber to provide added grip during use with oily hands and added cushion from from the pounding that all impact wrenches deliver.

Just as with the other air tools, the IM6100 takes the same Amflo Industrial Interchange Plug and attaches to the Power Tank Power Hose in the same fashion via the Coilhose Pneumatics Six-Ball Coupler.

This is John's favorite impact wrench and the one he uses with his PT-15 to undo large or very tight fasteners like wheel lug nuts.

Another very nice option for an impact wrench is the IM3100, also from Snap-on. This unit is substantially smaller and lighter than the IM6100, but delivers approximately 2/3 of the torque of the IM6100. However, the IM3100 delivers much more power than other similar-sized 3/8" impact wrenches.

The IM3100 is a nice alternative to the IM6100 in that it delivers a substantial amount of power, but without the size and weight of the IM6100. Best of all scenarios is having both on hand to suit different applications.

Like the IM6100, the IM3100 has a quiet mode and a full-power mode, with a selector to choose the mode desired.

When the selector is pointed to the "down" position,

the forward exhaust port is closed and the compressed air is directed down through the handle.

The air passes through a mesh filter and exits out of the bottom of the handle. The mesh muffles the sound of the tool and the tool is very quiet to use in this mode.

The selector can also be turn to the "forward" position, which will open the forward exhaust port and give the tool maximum torque. In this setting, the unit is no more or less quiet than other impact wrenches.

Like the IM6100, the IM3100 features a rubber-coated handle with ergonomic shape to maximize grip and user comfort during use.

One key difference between the IM6100 and IM3100 is that the IM3100 features interchangeable anvils, what Snap-on terms its "Versadrive" system. Each IM3100 comes complete with both 1/2" and 3/8" anvils. Furthermore, Snap-on offers a plethora of different anvils for the IM3100 to suit different applications, such as locking and swivel models.

Both the 3/8" and 1/2" anvils feature the same spline pattern.

The front of the IM3100 will readily accept either anvil without modification.

Simply fit whichever anvil you want to use. In the left photo above, the 3/8" anvil is fitted. In the right photo, the 1/2" anvil is fitted.

Securing the anvils is very easy. In the above photo, the anvil has been inserted but is not yet secured.

A steel collar is provided that slips over the anvil and into the tip of the tool's body.

Slide the retaining clip into the apertures in the tool's body and over the steel collar.

The retaining clip snaps into place and is held securely.

Refit the tool's vinyl boot and you are ready to attach sockets. Always use only impact sockets with your air tools.

Fitting the 1/2" anvil permits fitment of all 1/2" impact sockets, like the 1 1/16" Land Rover lug nut socket shown above.

Like the other air tools shown above, the IM3100 has the standard 1/4" NPT female-threaded and accepts the Amflo Male-Threaded Industrial Interchange Plug.

And like the other air tools shown above, the IM3100 instantly and easily attaches and detaches from your Power Tank's Power Hose via the Coilhose Pneumatics Six-Ball Coupler.

Whether you choose to purchase a smaller impact wrench like the IM3100 or a full-size unit like the IM6100, or both, will depend on your particular needs and preferences. Rest assured that the Power Tank can handle them both easily.

As you can see, the Power Tank is so much more than for only inflating tires. Whether you use your Power Tank to power your Heavy-Duty Inflator, air chuck, blow gun, air ratchet, impact wrenches, or all of the foregoing and more, fitting the right plugs and couplers to your Power Tank and air tools will permit you to swap tools easily for the job at hand.

 

Is CO2 Gas Safe For Tires And Air Tools?

Yes. CO2 vapor is inert (nontoxic and noncorrosive). CO2 vapor is also perfectly safe for tires and wheels. CO2's thermal expansion rate is similar to air (~1 psi change per 17 degree F temperature change). CO2 is considered a "wet" gas because it does start out in liquid form but the amount of moisture content per cubic foot of CO2 vapor is less than the air emitted from the average air compressor. There is no need to worry about running air tools with CO2 either. Just maintain your air tools to the manufacturer's recommendations with proper air tool lubricant.

The numbers in the chart are average figures for average air tools. As with all of your equipment, buy only quality air tools. Besides being less durable, cheap air tools are inefficient and use more air to produce the same results as quality air tools. Also keep your tools lubricated as recommended by the manufacturer.

An example of air tool efficiency is the Snap-on IM6100 shown above. This unit produces a true 550 ft. lbs. Of torque going forward, 625 ft. lbs. Of torque in reverse, and 1300 blows per minute. Yet the unit needs only 90 psi to operate at peak efficiency and draws only 4.3 CFM of air flow. Many other cheap impact wrenches require 130 psi and need to draw much more air to achieve similar performance ratings. Your Power Tank needs and deserves good quality air tools.

Can The Power Tank Seat Tire Beads?

Yes. Running low tire pressures often leads to a rolled tire off its bead. This situation can be dangerous or in the very least a time consuming repair.

This is another reason to get the Coilhose Pneumatics Six-Ball Coupler for your Power Hose. One of the advantages of the awesome power of the Power Tank is its ability to seat tire beads quickly and easily without the need to remove the tire or hassle with a tire tourniquet. Simply lift the corner of your vehicle with the unbeaded tire. Get the tire straight and clean on the rim. Remove the core of the wheel's valve stem.

Set the outlet pressure of the SuperFlow regulator anywhere from 150 to 200 psi.

While holding the tire straight on the rim push the end of the quick-release coupler straight over the stem and give 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 "pops" over the rim bead. Remove the hose from the valve stem and replace the valve core. Reset the tire's pressure to the desired level, lower the jack, and you're on your way.

 

Can I Use The Power Tank To Inflate My Air Mattress?

Yes, but you may not want to. The Power Tank is a serious tool that should be used only where high pressure energy is required, such as airing up tires, running air tools, reseating tires, or running air lockers. Inflating a mattress would be a waste of energy that you may require later to get you through the trail and back home. Use your 12-volt compressor or blower for your mattress and save your Power Tank for more serious tasks.
