Filling with nitrogen

Hi,

I am considering purchase of a nitrogen fill system. I don't have power
at my tiedown, and filling the tires with a 12 volt portable compressor
is a pain due to having to park the car near the tire, move to the
other side, etc. I figgured a nice nitrogen tank system would give me
a power free solution and fill the tire with the best possible kind
of gas.

I found a fill system online:

http://www.aircraftspruce.com/catalo...trogenTire.php

My only question is why it says "no struts". That would seem to me
to be one of the best uses of this system, that I can top off my
strut, which is forever going low (on a Cessna). Is there a reason
for this restriction, and is there a system that can do struts?

Thank you.

Another point on this, I note that the same company is selling a
hand pump for both tire and strut use:

This is completely confusing to me, why would just pumping air into
the strut be ok, but nitrogen not ok?

It's just a WAG but it maybe certification issues.

On your first "tank" solution, I suspect that the mentioned "pressure
reducing single stage regulator" doesn't go up to the pressures
neccessary for struts (usually atleast 150 psi).

I have a strut pump, as well as a high pressure tank that I use for my
struts. I only consider the pump as a backup. Nitrogen is best. I
think that it's a waste of time in a tire.

May I ask, where did you get the high pressure setup for struts?

This works just fine for struts:

In my case, I sorta' "inherited" it from a airport old timer that lost
his medical and was getting out of aviation. My strut pump came from
Bogart (the same people that sell the Piper battery box mod and copper
cable mod)

A $40 ten gallon air tank is way more than enough for tires.

Expensive.
My set up costs:
Bottle of Nitrogen is about $100
A set of victor guages that the refirgeration guys use is about $110. 0-600
PSI on the low side.
$13 for the gooseneck to fit the schrader valve and $25 to have a long
hi-pressure hose made.

Keep in mind that it a takes high pressure to force the schrader's needle
valve open.

Agreed. I have a 5 Gallon tank (purchased for about $20 at Kragen) which
I take home to fill using my compressor about once or twice a year. With
no power in the hangar, this little tank works great to top off the
tires. It works well enough that I haven't bothered to keep track, but
I'd guess that I can put 2-5 lbs in all three tires for some 5 to 10
occasions before I'd need to refill the tank.
