Compressor setup help.

[gingerbabe]

I put thjis in the tech section but really need help asap since I need to go buy the parts today. Any idea on where I can go for this stuff locally?

I'm putting a Zip locker in my vehicle and I need to find the fittings and air lines to hook up the compressor and air tank. I only have one weekend to work on this so I've got to make it count!

So here's my idea. Use two cheap masterflow 1050 compressors to fill a 2.5 gallon tank (I don't room for anything larger) that will then feed my locker and also provide air for filling up tires.

Things I have:

- Hose that came with the zip locker
- Switch that came with the zip locker
- Pressure valve that came with the zip locker
- 2.5 gallon cheapy tank that I'll probably have to tap out to make work
- Two Masterflow 1050 compressors (very good little guys for the money).
- 1/8" NPT 85psi-110psi switch

Things I need:

- 60 amp relay that won't burn out being run for up to 20 minutes at a time (when airing up tires).
- Plumbing/hoses to connect the compressors to the air tank
- Possibly some kind of a check valve so the compressors aren't under
constant pressure
-Connector from the tank to air hose that I can run to the zip locker pressure
valve <<<----- This is the one that I'm most worried about
- 1/8" NPT to 1/4" NPT adapter
- Fittings for air hose
-Switch to connect to the relay and turn the compressors on and off
- Power wires for the compressors. Should need no more than 10 ft so I'm thinking 8 gauge?

Any suggestions on both where to find the parts above and on how to connect everything?

The best place to find fittings and hoses is Evco. Electrical stuff I'd try Radio Shack. To connect everything, try Kilby's on board air website. Maybe that all will get you started...

I have some used medical oxygen tanks that I think would make great air tanks for an off road rig. Probably 20" long, 4" dia. I'd sell'em cheap!

Any idea how many gallons they hold? What kind of fittings are on them and how many fittings? Are they steel? If so does anyone know where I can find weld in inserts for NPT fittings.

All the fittings on the tank I have are I think metric since 1/4" NPT fittings don't really thread in.

Gallons, I have no idea. Aluminum tanks. I think they're just standard plumbing fittings. I also have a smaller one I need to take to the hardware store and see what fitting it'll need to convert to a small low pressure air system. I think you can get a brass fitting that''l bring it down to a 1/4" npt.

Looks just like the tall one in this pic...

I have two tall tanks and one small tank.
