Another OBA setup with sliders as air tanks
I completed and tested out my OBA setup and I'm pleased at its performance. We spent all last week camping at Death Valley and it was nice to be able to blow out the air filters and the interior every night at camp. At the end of the trip, I filled up my tires of course.
This setup works like any other OBA, a pressure switch tells the air comp to turn on (at 80 psi) and turn off (at 105 psi). I picked this range of switch because an ARB air locker can handle this pressure w/o the need for a pressure regulator.
The air from the air comp goes into a manifold where there are multiple ports for a press switch, popoff valve, air locker solenoid valve, pressure gauge and spare ports. The manifold mounting bracket is a simple piece I welded up and bolted to the PS bracket so it's easily removable in the future.
The compressor is Air Zenith OB2 and comes with its own cooling fan. The performance is outstanding and the rebuild parts are available from Air Zenith. USA made product that will last a very long time. There is a check valve along with a high heat output hose that comes with the air comp.
The air tanks are my DIY sliders and this helps the air comp cycle less frequently. I still would like add two more alum tanks under the floor, between the sliders and the chassis rails. Any time you have air tanks, only helps out the air comp.
The comp sits on a DIY bracket on the passenger fender, next to the air box. For vibration reduction, I used vibration damping feet between the mounting plate and top of the fender. The vibes can still be felt but at acceptable level.
The air comp is being fed by an 80 amp ALN fuse and the air comp activate switch in the cab is getting its power from an aux fuse block. The switch came from CH4X4 and it's an excellent product, fit and finish for the money. The 80amp relay provided by Air Zenith is a joke in my opinion. It uses spade female connections which we know will open up over time. My air comp is used on Ebay and I can see the spades are already opening up a little bit. As you know, a poor connection makes for higher current draw and more heat which is no bueno for this application. So I opted for a 100 amp relay with ring terms from Amazon.
Well anyway, enjoy the pics and let me know if there are any questions.
