Extreme Air

I have posed this questtion before, but now since we have a true expert with us I will ask again. I have the extreme air, and tank. I am told to install a tee in the system to allow a more direct route for air for air ups.
Does anyone know at what pressure the tank pressure regulator kicks off the compressor? Is there an approximate time for this tank to fill?
When I last checked mine, an 07, the compressor pump never did shut off and I did not notice any air bleeding off, as the pump ran. I am assuming the pump will shut off when the tank is at a certain pressure. Right or wrong?

Extreme Air

Hello Patrick,

You can reach the expert, George @ Extreme Outback Products at (866) 447-7711 or visit his web site at . George is a true gentleman to deal with and will give you straight answers (as is/will Heber at SMB West).
I'm not entirely sure of the benefit the "tee" will provide, if the system is working properly. Your system does not sound like it is working right. There is a high pressure cut-off switch which I believe is set at 140 psi. If I remember correctly, the 2 gallon tank should fill in about 3-4 minutes at lower elevations. There have been some compressors that needed the head tighened/replaced, but most of the time a compressor would run continuously was because of leaks at the fittings.

FYI, the 80 amp circuit breaker for the ExtremeAire is usually located under the van on the passenger side, behind the side door step, outboard on the Ford frame. (There were many calls on where it was located, so I thought I'd throw this bit of info in too.)

Good luck!
John K.

Since it doesn't sound like there is a pressure guage on the system (?) you can buy one in the air compressor/fittings asile at any hardware store and thread it onto a quick connect that matches your system, pop it on and watch the pressure in the tank while it's filling.

Also let it run for a few minutes (with or without the guage) and turn it off. There should be:
A) pressure in the system (use an open fitting or blow gun)
B) no discernable leaks (hissing sound)

With or without the guage you can leave the system for awhile and come back and see if the pressure has changed or the blow gun doesn't work any more.

Depending on what you find you'll have a better idea of where to look for the problem.
it was good to be back
