I use the air tank on my trailer....when the tank is full (no air supply from the truck), I can purge my 2" hose twice.
I put a pressure regulator on my airline set to 20 psi. That is plenty of pressure and reduces the risk of over pressurizing the hose.
My Patriot sprayer has the fill lines connected to the pump supply....so, if I purge the nurse trailer hose with air when the sprayer product pump is running, it will blow air and run the product pump dry for a bit....have to make sure that the product pump is off.
