Air Line from Onboard Compressor
I have plumbed into the air tank to run my auto rod shortening system and have also put a nitto connector on for air to tyres.

Photos as promised:

It is important to hae the valve in to put the connector on and to take it off. (you can take it off with it open but it makes one hell of a noise and goes flying. )

Tank pressure after being left for 20 hours:

Hose is rated at 250psi working pressure so should not be problem having full pressure.
Nine litres @ 210psi = how many litres @ 36psi? and how many litres is in a tyre at say 36psi?“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Approx volume of stock tires is 55.5L @ 14.5 psi (1 bar) so 22.3L @ 36 psi.

I wont scribble the maths down, but I estimate the comp will pump one flat tyre to 36psi(and have such in it it's self too). They're about 1:5 vol. ratio ..........
How long does an empty comp take to fill ?

So could even be used for repair?
Plenty of air for airing up after being on sand.
A pressure of 230psi would explain why I had trouble with air lines busting and leaks.
Hopefully solved now.“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

I hope you guys are all aware of the dangers of compressed air at that pressure ?
Let the tyre inflation nozzle off on or near you body and the air can go straight through your skin into a vein and give you an instant embolism.
I would strongly advise you to fit a regulator to bring the tyre line pressure down to say 60psi or less..

There are bigger problems with air than embolisms.
"An air embolism, or more generally gas embolism, is a medical condition caused by gas bubbles in the bloodstream (embolism in a medical context refers to any large moving mass or defect in the blood stream). Small amounts of air often get into the blood circulation accidentally during surgery and other medical procedures, but most of these in veins are stopped at the lungs, and a venous air embolism that shows symptoms is very rare. Death may occur if a large bubble of gas becomes lodged in the heart, stopping blood from flowing from the right ventricle to the lungs (this is similar to vapor lock in engine fuel systems). However, the amount of gas necessary for this to happen is quite variable, and also depends on a number of other factors, such as body position."
"Gas embolism into an artery, termed (arterial gas embolism), or AGE, is a more serious matter than in a vein, since a gas bubble in an artery may directly cause stoppage of blood flow to an area fed by the artery. The symptoms of AGE depend on the area of blood flow, and may be those of stroke or heart attack if the brain or heart (respectively) are affected. "
Embolism from compressed air is usually from inhaling it as a diver and getting the bends. Extremely unlikely from compressed air use. Not enough air would go through the sin unless there was an open wound. (which could be caused by compressed air) It also takes a reasonable amount to cause a problem.
See: http://www.chestjournal.org/content/7/4/146.full.pdf he doesn't quote any cases of compressed air injuries.
Yes you have to be careful using it. but let's not be paranoid after all I am assuming we are responsible adults.
Compressed Air Kills:
Do not do this:
In the U.K., workers were cleaning their clothing with compressed air. One worker stuck the hose between a fellllow worker’s legs, from behind.
The man suffered bruising and bleeding in the rectum; shock; air in the tissues around his stomach, chest and neck; his hernia canals in the groin area filled with air; the abdomen filled with air; his lower bowel was torn open in 3 places; the abdominal cavity filled with bowel material and blood from his lower bowel; and the lining of his abdominal cavity was torn in several places.
Despite surgery, hedied 3 days later.
A regulator dropping the pressure would be a good idea as that much pressure is not needed and used with a cleaning jet would be very dangerous. You will need a non-venting one.
Putting 230psi into your tyre could give you an even bigger problem.“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

I only mention it because when I was an apprentice at Mullards in Mitcham Surrey, some 30+ years ago a fellow apprentice pushed a non vented blow nozzle against the the skin of another apprentices leg, through his trousers, and released the air. The 'victim' died as a result.
This wasn't up his , or in a wound and the pressure was a LOT lower than 230 psi, about 100psi IIRC.
I am not a do gooder or the safety police, far from it, I love a bit of 'edge' as much as anyone but just please be careful with compressed air guys.
P.S. My old dad used to say "you don't know if no one tells you".

Thanks London Lad
Appreciate the warning to all.
A blow nozzel gives a very fine jet of air. It would have cut a hole into his leg and then air may have got onto an artery.
Recomended air pressure for a blow nozel is only 30psi.
Originally I thought the pressure in the air tank was aonly 150psi but at 230 needs extra respect.
But it gives enough air to be useful. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Sure does, I'll be adding a take off as soon as the weather improves!.

You've long time to wait.
Was 45 degrees C two days ago really cold now only 26 degrees. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

caverD3, have you fully tested it out yet? Just curious how the suspension system responds to a significant volume of air taking an alternate route.
Also, did you mention that the fitting to the tank was special in some way?
