A/C into onboard air

ok, so i turned my a/c pump into onboard air and it is awesome! i can air up tires faster than air down and run air tools like rattle gun this is the first time i've made a thread like this so bare with me.

parts needed: 1/4 inch npt T
1/4 to 1/8 reducer bushing
15 feet of 300psi air hose
pressure switch, on at 100psi, off at 150
some wire and connectors
toggle switch
barbed hose fittings (the ones you push in and hose clamp)
misc. air fittings
one pod filter with a half to 3/4 inlet
an air tank(i have one i had for testing and temporary but am going to
build one that fits under my toolbox)

so i cut both the rubber lines as long as possible coming out of the a/c pump (my system was already discharged, this should be done by a professional) then put a 1/4" npt male hose fitting on the discharge line, attach the T. then the reducer and pressure switch to that. then off the straight part of the T your 15' air hose. the little filter goes on the intake. then wire the pressure switch to the hot wire on the a/c unit (very self expanitory, there are only two wires and one is grounded to the pump) and to the toggle inside the cab, then of course to the battery. then you hook your hose to the tank, then come out of the tank with your tool hose(the one you will air up tires with) start the truck, flip the switch wait two minutes for 150psi(you hear the compressor shut off) then air em up

i know i probably suck at this so any questions just ask. i love it! it works great! way better than a plug into the cigarette compressor.

oh, and now you only have the 2-80 air conditioner but i dont mind.

this only cost me about 40 bucks but i had a lot of this on hand. probably around 60 at home depot. plus the pressure switch that i got from custom truck

 

great idea, id do it in a second if i didn't want to keep my ac. nice write up.

 

Huh, no shit , I'd never even thought about this, but you still need the engine running ,correct ?

in any event thats an interesting idea none the less , if it holds up, bravo !! if not back to the drawing board. props for thinking outside the box...

 

very nice !!

 

thanks, and it is still workin awesome!

 

I built a system like this for my 1984 Toyota rockcrawler, worked great.
Those A/C compressors rely on a lubricant in the freon. Without that
they will overhead and destroy themselves after a while.

I went thru 2 compressors in 8 years, even though I would manually add
compressor oil before each offroading trip.
