Portable Air Compressor on Sale

One thing I haven't seen mentioned anywhere is about the DP chassis owners tapping into the air system on their chassis and using that for pumping tires and other maintenance.

Chassis air systems cycle between a bit less then 100 psi and up to 120 psi.

So attempting to put 110 psi in a tire is an adventure. As you draw down the air it flows out of the tire until 100 psi. Then it pumps to 120 and you get some air back in, but not before the system drops below 110 psi again.

Owners have tricked the system to only add air when the system is at max pressure, stop filling and bleed off the system, to build again, and then add some more. Nothing better then a 1/2 million $ tire pump.

I have the Craftsman version. Inflates my 125psi tires no problem.

The air brake system should max out at between 120-125 PSI. There is also an add on air compressor that is (was) available that runs from an external drive pulley, but then you have to add the additional air tank, and that is too much for no more than it would be used.
