When we say Automatic, we really mean Automatic...

The Premier Nitrogen "Filling Station" is the only machine on the market with
individual tire pressure monitoring.  Why is this important?  What if you want
to service a vehicle with different front and rear tire pressures?  With other
systems* you will have to go through two service cycles, one to fill the front
tries and then another to fill the rear tires. Since the laws of physics
dictates the time to purge and fill and then purge and fill again (normal
procedure for 97% N2 concentrations) would be approximately 10 minutes,
servicing the above dual pressure vehicle would take 20 minutes minimum.  Now
add the spare tire to the equation (the most important tire on the vehicle for
conversion) and it will take approximately 30 minutes for the entire service.  
On the other hand, the Premier N2 Filling Station, requires a total time of only
10 minutes for this vehicle.  And that's for up to all 5 tires!  You don't add
on service cycles, since all tires are filled at the same time and at the
correct individual pressure setting according to the O.E.M. specs.

* Parker, Branick, Ingersoll-Rand, Nitro-Fill, PurigeN98, Ultrafill99, RTI, Tire
Last, etc. 

You might wonder why we list our competitors on our web site, some you may not
even know.  You might ask, aren't we afraid you'll call them and compare?  Well
actually we are hoping you will.  Please call any one of the above companies and
ask if their system can fill all five tires (or more) while individually
monitoring the pressure in each tire during the purge and fill cycles. 

They may try to explain they have 4 or 5 hoses like the Premier System, but
they'll conveniently forget to mention all those hoses are attached to a single
manifold log with one single pressure.  If you want to fill different pressures
on the same car, at the same time... you are out of luck.  If they are willing
to admit they use a manifold, ask them how they compensate for the uneven final
purge pressure and gas volumes, when their system shuts down based on "average"
pressure as defined by the log sensor.  If this sounds a little complicated
don't worry too much, they probably don't know what it means either or that it
is technically important.

 

By now you're probably thinking you can't afford one of the Premier Nitrogen
Filling Stations.  Be prepared for a pleasant surprise because you won't spend
$6,000, $7,000, $8,000 or more, as is the case with the less sophisticated
machines from our competitors.
 



Note:  Newly Designed, Technically Advanced "Premier N2 Generators" are now
available....
with prices starting at under $4000.


No one can sell you the top quality,
fully automatic Nitrogen tire filling system for less!

We unconditionally guarantee it!

 Plus we have available the "only" fully digitally controlled touch screen
system on the market, it light years ahead in technology.
 


Why buy a GWR Premier Nitrogen Filling Stationtm

GWR's revolutionary design automatically delivers a consistent 99.99%
concentration of Nitrogen to the tire, something no generator system can do. 
Interestingly though, some manufacturers do claim they can... on their web
site.  (IE: " NitroFill™ generators can produce nitrogen in excess of 99.9%
purity and provide the procedures to guarantee a minimum of 95% purity in the
serviced tire, which is the minimum allowable purity that must be maintained in
the tire to enjoy the benefits that nitrogen provides.")  Well they are almost
right with the 95% in the tire, it's actually 97% that's required to get the
benefits.   Our problem with the statement is, its impossible to consistently
get 99.9% with a generator due to inherent problems with membranes, feed
compressors, filtration and run time.

In comparison our tank systems, Nitrogen "Generating" machines fluctuate gas
concentration by as much as 10% as their membrane filters become clogged with
contaminants and oils from the shop's air supply. Worse, the net cost per tire
runs from an absolute minimum of $1 to as much as $4... based on fixed yearly
maintenance costs, the condition of the Generator's filtration and membrane
system itself and the quality of the supporting air compressor.  Remember that
the longer their system runs, the longer it takes to regenerate N2 because
filter contamination grows and flow rates decrease with every hour or usage.

We thought you might be interested in reading an excerpt
from a manufacture of generator systems.
This one is actually honest about the limitation of membranes.

"Since membranes start degrading immediately, a customer's unit will
over-perform at first. If, however, we put high-pressure air through the
membrane and/or pushing high volumes of air through the unit to increase flow,
the unit will degrade much faster.

If you think of the logic, it’s obvious: Membranes degrade because molecular
particles which get past filtration plug the holes through which the O2, CO4,
CO2 molecules ferment. The more air and the higher the pressure (more excited
molecules bouncing around, moving, giving a better chance for impurities to plug
holes) the more quickly the membrane deteriorates.  Since the membrane is 85% of
the cost of a membrane system (I.E. $3,000 to $5,000), things go downhill pretty
fast.

In general... as membrane purity goes down, customers must increase flow of
input air to ensure volume and purity. Each time more air is added though,
degradation of the membrane becomes faster and faster."


If this scares you and it should if you have a limited budget, you are a
candidate for the Premier Nitrogen Filling Station!  Because there is no
expensive membrane to replace down the road, the consistent final cost per tire
with a Premier Filling Station is only .25¢ to .50¢, that's less than $2 per
vehicle!  Not bad when you consider the average retail ticket for four tires is
$30 to $40.  Yes, a 1000% to 2000% mark-up with virtually no labor or parts...
plus our exclusive touch screen allows anyone on your staff to perform the
simple service with only 5 minutes of initial instruction.

Do the math and you will see how the GWR Nitrogen Filling Station (tm) creates a
400% greater profit margin with 1/4 the labor time.  Our machines don't just put
"nitrogen in tires", they do all four (or 4 plus spare) at one time,
automatically! Generators, on the other hand have one hose and take 30 to 45
minutes to do the same service.  If they happen to have added more hoses now to
keep up with the Premier System (so called "new and improved" models), they
still take 30 minutes or more on a multi pressure vehicle.  In contrast, simply
set the various tire pressures on the Premier Nitrogen's Color Touch Screen,
push the start button and walk away.  In about 10 to 12 minutes all four or five
tires, will have been purged and filled twice with virtually no labor on the
technicians part.  Most important, there is no waiting time to "make more
nitrogen" after two or three are filled, like some generators systems.  Can you
or your customer wait an additional 10 minutes to an hour, for the generation
and storage of more Nitrogen if a machine ran out during a service?  That's
asking a lot!

Note:  Our systems can be configured to fill more than one vehicle at a time,
with no waiting.  If you are a busy multi-bay shop this may be a money making
option for you!  Remember, with our tank distribution system, there is never a
wait to "generate" more Nitrogen before the next fill job.  You can even add
multiple tanks with our exclusive automatic tank pressure monitoring system...
it allows you to fill vehicles for weeks or even months without touching a
tank.  Additionally there are new features now available that we decided not to
discuss here, to keep from competitors eyes.  It's only fair they should have to
research and develop new innovations like we do, not just take them from more
progressive companies like Premier.

After all this, we still offer more...

 GWR's exclusive design reduces your initial cost when compared to big name
generator filling systems.  They may have the name but they do not have the best
system, that's a guaranteed fact!  For example, what if there is a break-down of
your generator machine?  Can you afford to wait days of weeks for a service
technician to come to your location?  Worse, do you want to crate the monster
machine at your expense, to send it back for repairs that may take weeks or
months.  If you purchase GWR's Premier Nitrogen Filling Station(tm) you won't
need to, ever! On the slight chance you ever encounter a problem with our state
of the art technology, you simply disconnect the hoses, unplug the power cord
and then remove the entire top panel from the main metal housing/cart.  The 20
lb "brain" can then be sent via the US Postal Service, FedEx or UPS, for a quick
repair at our factory.  Again, with our exclusive design, the whole repair
process requires only one day in-house, before we turn it around.  Check out the
warrantee of the big names and be sure to read the fine print... most are fully
warranted for only 1 year, not the 5 years they claim.  Additionally, you must
buy expensive multiple filters exclusively from them and follow a rigorous
extensive maintenance schedule, otherwise you void the entire warrantee. 
Finally, they make sure they are fully protected by stating your warrantee is
void if they find one speck of oil in the membrane.... something virtually
impossible in a shop environment.

A final though about "generators"...

You may be unaware of this fact, "generators" require the continual replacement
of their expensive membranes ($3000-$5000) and multiple inline filters. Their
salespeople will tell you a membrane last for 5 to 10 years, but they are
talking absolute perfect conditions with an air compressor/filtration system
that would cost you $10,000 minimum.  Reality is, there's no way to change this
"built-in" design problem, so actual "real cost" of a generator's maintenance
will probably be $1000 to $2000 per year. We regularly get calls from shops
telling us they have replaced membranes within a year of the new purchase... at
a cost in excess of $3000.   Worse, that amount does not include the enormous
cost of electricity required to run a 12CFM or higher, 2 Stage, 175PSI air
compressor, or the ware and tear on it.  (Note:  Standard shop compressors can
run 3, to 4, to up to 8 hours per day since their volume and or pressure is
generally not sufficient to push a high volume of air through the O2/N2
separating membrane, plus the production ratio of O2 to Nitrogen is about 3 to
1.  Additionally, shops may have to wait for extended periods of time for a
generator system to manufacturer more nitrogen, possibly on a single vehicle.)

Amazing facts "they" don't want you to know:

A membrane's capacity to produce nitrogen will drop 61% when you try to increase
nitrogen purity from 95% to 99% (example 8 scfm will drop to 3.1 scfm). 
Additionally, membranes will lose the capacity to produce nitrogen when the
temperature drops in the shop below membrane ambient operating temperatures,
normally quoted at 68 degrees to 75 degrees.  On the average, for every one
degree of temperature drop below these operating ambient temperatures, a
membrane will lose .9% cubic feet of gas production.  This condition could be
overcome by heating the air feed, however this adds additional operating
expenses, plus the initial cost of new equipment.  Any way you look at it...
membranes are expensive initially and for the long run!

Something new "they" came up with!

We found out something interesting while displaying our Premier Nitrogen Filling
Station at the 2006 SEMA show in Las Vegas, a few years ago.  Several of the
most powerful companies selling nitrogen generators had gotten together and
formed a so call "information organization" to tout the benefits of nitrogen to
the general public.  Interestingly they have limited their founding and
controlling members to four* companies, the "big" generator manufactures
(surprise, surprise).  Additionally, they are directing the information coming
out to the public so that it seemingly supports a new opinion that you only need
a 93% final concentration of nitrogen in tires.  We find this disturbing yet
expected, since most generators can't fill tires with a greater than 93%
concentration.  From the beginning of tire testing and discussions on nitrogen,
all scientific testing and engineers in the rubber and tire manufacturing field
have supported the 96% number as the absolute minimum.  Now, all of a sudden,
non scientific based companies who only "assemble or re-label equipment" come up
with a "new" theory. One that supports their limitations!  Who are we to
believe?   Does it sound logical that replacing air with nitrogen in a tire is
beneficial, yet you don't need to change as much as is physically possible? 
They state that at 93% N2 concentration, we achieve a balance between outside
and inside saturation levels of O2.  To make their theory plausible, I honestly
believe they would need to change the law of physics.  I could be wrong, but
someone would have to explain how air (oxygen) would go into a tire (through the
walls) when exterior air pressure is 15psi and interior tire pressure is 30psi
or more.  That's like trying to blow air into an inflated tire, with a hose and
your mouth.  Please don't fall for this one, I believe technicians and shop
owners are smarter than that.

* 2009 Update:  One of those big four founding members has gone out of the N2
generator business because of all the headaches they were encountering with
membrane systems.  Be glad that you did not by one of their units a year or so
ago as service and parts are now non existent.

What is Nitrogen?

Nitrogen is a dry, non combustible, inert gas making up 78% of the air we
breath.  In the last 30+ years it has begun to find its way into the tires of
giant off-highway earthmovers and most every type of race car.





Across the globe, every major Airliner, Military Aircraft and even the Space
Shuttle uses Nitrogen...
Read an excerpt from the Federal Aviation Administration's web site on why they
mandated laws requiring all commercial aircraft use Nitrogen in their tires.   
Click here!



They main reasons are it improves performance, increases tire mileage, offers
better fuel economy and extends the life of the tire's rubber and steel
construction materials.

How does that happen?

Since air migrates through rubber, tires loose about 80% of lost air through
their sidewalls.  Like a balloon that shrivels up... but much slower.  That is
why regular inflation pressure checks are a must, even if nothing is "wrong" you
can still loose air pressure at a rate of 1 to 2 lbs per month.  As a note,
oxygen that passes through rubber sidewalls can come into contact with steel
cords causing them to rust.  Between accelerating the aging process of rubber
and corroding steel cords, oxygen reduces overall reliability of modern tires.

Adverse Effects of Under inflation!

Under inflation will cause high tire deflection and heat build-up, which in turn
may lead to ply separation.  Low inflation pressure may also cause uneven
wearing of the tread and rapid wearing of the shoulder areas.  Additionally
there is an  increase in the tire footprint and this increase will eventually
lead to damage of a tire's sidewall.  Running just a few pounds below the
manufacturers  recommended pressure, can let to failure.  Picture at left is an
example of Casing Break Up (CBU) in a bias tire at the lower sidewall caused by
running the tire at pressures below those recommended.

 

Why use Nitrogen?      

> 1.  Less inflation pressure loss
> 2.  Reduced wheel corrosion
> 3.  Prevents inner rubber deterioration by oxidation
> 4.  Tires run cooler
> 5.  Increases tread life
> 6.  Increases fuel mileage
> 7.  Helps prevent uneven wear

Please note that Under-Inflation is the leading cause of tire failure.
Twenty-three per cent (23%) of vehicles have at least one tire under-inflated by
more than 20%. Under-inflated tires on your vehicle lead to poor or delayed
braking, steering and acceleration.  Operating a vehicle with just one tire
under-inflated by 20% (8psi) can reduce the life of the tire by 15,000 km and
can increase the vehicle's fuel consumption by 4%.
    Oxygen in compressed air permeates through the wall of the tire, thus
reducing the tire's inflation pressure. During it's journey through the tire
wall, oxygen oxidizes the rubber compounds in the tire, causing under-inflation
and deterioration of the rubber.
 

The Effects of Under Inflation on Tire Wear and Fuel Use Percentage of Under
Inflation Percentage Wear Increase Fuel Use Increase 10% 5% 2% 20% 16% 4% 30%
33% 6% 40% 57% 8% 50% 78% 10%

Dry nitrogen will maintain proper inflation pressure and will prevent
auto-ignition, will not corrode rims, extends valve core life, and will help the
tire to run cooler.
 

 

The biggest advantages - Improved tire life!

Experts in the tire industry indicate that oxidative aging is one of the primary
causes of decreased tire life. Oxidative aging is caused by the diffusion of
oxygen from the pressurized air cavity of the tire to the outside atmosphere.
Tests have shown that if tires are inflated with nitrogen, there is a
significant reduction in tire failure


Why did race cars, military and off-road vehicles switch to Nitrogen?

Air is about 1/5 Oxygen, and oxygen, especially at high pressures and
temperatures, is a very reactive element.  When oxygen reacts with things, the
process is called oxidation. When oxidation is extremely rapid, it's called
"burning. That's one reason nitrogen is used in off-highway and aircraft tires.
These tires run so hot they can actually catch on fire. Nitrogen doesn't support
combustion, so nitrogen-filled tires don't add fuel to the flames. And nitrogen
helps prevent slower forms of oxidation also.


Nitrogen prevents other types of corrosion as well

 

Oxygen and moisture corrodes aluminum and steel wheels. Oxygen also reacts with
rubber, another type of "corrosion". When this corrosion starts, the small
particles break off and form rust and dust, which can clog valve cores, causing
them to leak. The rough surfaces created from the corrosive action on the wheels
leads to tire beads that don't seal properly, causing additional leaks .

Oxygen also ages the inner liner, the thin layer of rubber inside the tire whose
function is to keep air away from the carcass. As the inner liner ages, more and
more air molecules can pass through it, causing more pressure losses.  As it
passes through the rubber, the oxygen can also corrode the steel cords, causing
them to rust too.




Small bits of dust and debris as a byproduct of oxidative corrosion to the
wheels and alloy rims can lodge in the valve core seat, causing air leaks.

Nitrogen also will not degrade the rubber seal in the valve core which extends
valve core life and helps prevents core leaks.



How does Nitrogen help?

While both nitrogen and oxygen can permeate rubber, nitrogen does it much more
slowly.  These pressure losses in a tire can average up to 2 psi a month as a
result of the air passing through the sidewalls. On the other hand it might take
6 months to lose 2 psi with nitrogen. And nitrogen is far less reactive. It
doesn't cause rust or corrosion on steel or aluminum, and it doesn't degrade
rubber. Wheel surfaces stay smooth and clean, rubber remains supple and
resilient.


Any other reasons for using Nitrogen?

The air around us is full of water vapor, it called humidity!!!  Compressing air
concentrates the water in it. Draining the water from your compressor tank daily
helps, but unless you have a really efficient air dryer system, chances are that
there's a lot of water in your compressed air.

Remember physics 101...  When you compress air, it takes up much less volume,
but the percentage of water by volume is greatly increased!
 

...and what harm does this moisture cause?



Water vapor in compressed air acts as a catalyst, accelerating rust and
corrosion.  Water vapor also absorbs and holds heat. And when it changes from
liquid to vapor, water expands tremendously in volume.

As a result, tires inflated with wet air tend to run hotter and fluctuate in
pressure more. That's one of the reasons why racing tires, where fractions of a
psi can radically change the handling characteristics, are inflated with dry
nitrogen.

 

 




Did you know???

Interestingly, all gas molecules in the tire move and react based on their
molecular size.  Nitrogen being 4 times larger than Oxygen obviously leaks out
much slower!  The bottom line.... tire maintenance is reduced drastically along
with actual tire wear.

 

Think you know when a tire is under inflated?
When is your tire 10%, 20%, 30% low?

Check out this incredible graphic...
 

Checking Tire Pressure as recommended by NHTSA

It is important to check your vehicle's tire pressure at least once a month for
the following reasons:
 * Most tires naturally lose air over time, between 1 and 2 psi per month.
 * Tires can lose air suddenly if you drive over a pothole or other object or if
   you strike the curb when parking.
 * With radial tires, it is usually not possible to determine under inflation by
   visual inspection.
 * Loss of just 20% of the recommended normal air pressure can reduce fuel
   mileage about 10%

Flash video of various tire pressure levels

Every vehicle should have a tire pressure gauge in the glove box or trunk of the
vehicle.  Digital or inexpensive digital gauges can be purchased at tire
dealerships, auto supply stores, and other retail outlets.

The vehicle manufacturer's recommended tire inflation pressure is the proper psi
when a tire is cold. The term cold does not relate to the outside temperature.
Rather, a cold tire is one that has not been driven on for at least three hours.
When you drive, your tires get warmer, causing the air pressure within them to
increase. Your tires can get warm after just 1 mile of driving.

Therefore, to get an accurate tire pressure reading, you must measure tire
pressure when the tires are cold or compensate for the extra pressure in warm
tires.

Just the Facts.....

NHTSA RESEARCH....
Chemical aging is due to oxygen diffusing through the tire composite and
reacting with the internal components. If the rate at which air diffuses through
the tire is slowed, the rate of chemical aging will be similarly slowed. (Review
the FMVSS 139 for additional information on mechanical aging effects.)

AIR PERMEABILITY TEST PHILOSOPHY....
According to tire manufacturers: - tires with more expensive, 100%
halogenated-butyl inner liners lose air at a rate of 2.0-2.5% per month (10 lbs
per year @ 35 psi)- tires with cheaper, blended butyl inner liners lose air at a
rate 4.00-5.0% per month - for the same inner liner compound, a thicker inner
liner will lower the air loss rate - a reduction in air loss rate, by a factor
of 2, may be achievable for some tires.

NITROGEN TEST....
In on the road tests involving over 7 million miles of truck tires inflated with
nitrogen, tire failures were reduced by half and tread life increased by 25% to
30%. The benefits were repeated in the second tire life after re-treading. These
mileage comparisons were followed by electron microscope analysis which measured
oxygen levels in the tire body and tread of tires inflated with air and then
operated on the road until replaced because of failure or tread wear. The
results were conclusive; oxygen kills tires over time. Similar tests on
automobile tires yielded comparable increases in tire life. (Reference: Million
Mile Truck Tires – Available Today by Lawrence Sperberg.)

NITROGEN STUDY....
In a study reported in Rubber and Plastic News by David Coddington of Exxon
Chemical Co. material from tires run for varying periods of road service and
inflated with air was tested for tear strength. The laboratory findings;
strength values are steadily decreased with increasing service mileage, leveling
off at a value below 50% of original strength. In lab testing equivalent to less
than 40,000 road miles, the relative strength of oxygen exposed tires declined
to under 40% while the material from tires inflated with nitrogen held at over
80%.

TIRE DURABILITY TESTING.....
Tire life to failure point in laboratory wheel tests confirmed more than twice
the life for the nitrogen inflated tires. (Reference: "Factors in Tubeless
Radial Tire Durability", Rubber and Plastic News, August 1993.)

GOODYEAR BULLETIN.....
Nitrogen inflation has advantages in that tires will hold pressure longer using
nitrogen. Nitrogen’s diffusion rate is 25% to 30% lower than air, significantly
reducing tire pressure loss between inflation checks. Under inflated tires wear
rate is increased to the point where a tire 10% under inflated will lose
approximately 7% of it service life. On the other hand, properly inflated tires
have less resistance to rolling. (References: Goodyear Application Bulletin #17
and Bandag Tread Guide, September 1995.)

AAA (AMERICAN AUTOMOBILE ASSOCIATION)....
Under inflated tires can cut fuel economy by as much as 2% per pound of pressure
below the recommended level. Therefore a tire that is just five pounds below its
setting will consume 10% more fuel. Additionally, tires with low air pressure
are more sluggish in their response to steering input... compromising your
vehicle’s handling.

They endorse Nitrogen for tires!

“Goodyear supports the use of nitrogen, based on the ability of the tire to
retain pressure for a longer period of time.”

“Nitrogen can provide stronger casings for more retread ability.” “While both
nitrogen & oxygen can permeate rubber, nitrogen does it much more slowly.” "When
nitrogen is used as the inflation media, the change in rubber properties is
significantly slowed down or even halted." Michelin supports the use of
Nitrogen, based on its ability to better retain gas volume over a period of
time. "Tires inflated with Nitrogen will run cooler than those inflated with
air.  Nitrogen bleeds through the inner liner or tube at a slower rate than
regular compressed air." "Nitrogen reduces the risk of self ignition and tire
burst, if tires are overheated.  Due to its the reliability, we are very
satisfied with this service."  "Even the most energy-saving tires lose
efficiency if under-inflated. Nitrogen inflation systems help maintain tire
pressure because nitrogen does not permeate through tires as readily as air
does. Since the oxygen in air accelerates tire wear, a 100% nitrogen fill is
kinder to tires, as well."  EPA (Environmental Protection Agency - Federal
Government) “Nitrogen is slower to leak out through the casing than air and does
not carry moisture that can lead to rust in steel cords and cables.” Recently,
nitrogen gas (for use in inflating tires) has become available to the general
consumer through many retailers. General Motors does not oppose the use of
purified nitrogen as an inflation gas for tires. Nitrogen inflation can provide
benefit by reducing gas migration (pressure loss) at the molecular level through
the tire structure. NHTSA (National Highway Traffic Safety Administration) has
stated that the inflation pressure loss of tires can be up to 5% a month.
Another potential benefit of nitrogen is the reduced oxidation of tire
components.
