Building my onboard air system!
So I've wanted on-board air for a while now. I figured having an air horn would be a riot, but in addition, I am always needing to air up. I carry tire plugs and tools, and oftentimes flats I get are repairable. The problem occurs finding air late at night close enough to avoid damaging the wheel and tire. The last flat tire I had could have easily been fixed on the road without all the added drama of waiting around until morning to get aired up.
After this, I resolved to getting an onboard air system. I considered buying one of those all in one kits on ebay that included an air horn, and they looked great until I looked at tank capacity. Even the higher end models were limited to 1.5 gallons. That, and for the price, how long would a Chinese compressor really last? My buddy had one of those kits, compressor took FOREVER to fill the TINY tank, and ran all the time. With all of this in my mind, I decided that building my own was the only smart thing to do.
My parts list:
Viair 450c compressor-http://viaircorp.com/OffRoad/450C.html
I went with this one because the smaller units are only around rated to around 33 percent duty cycle. The 450c is rated at 100 percent, meaning it can run continuously if needed. In addition to having a max rating of 150psi, It will fill a 2.5 gallon tank to 150psi in 3 minutes flat. Let's see the ebay specials do that!
Viair 2.5 gallon tank-http://www.viaircorp.com/OffRoad/Parts/2_5gallon.html
Most tanks I looked at were dual port-basically an inlet, and an outlet. Not enough expandability for me. I found a 2.5 gallon tank that would fit under my toolbox, and had 6 ports. Plenty of room for expansion in the future, and dual gauges! (one in the truck, one directly off the tank). I am still up in the air about whether to ad a second tank-basically have a 5 gallon capacity. I guess I'll wait until I determine if I need more air.
I got the following for my system. 50' of plastic airline (the coil type), an in cab pressure gauge/switch, an on tank pressure gauge, 110on/150off pressure switch, and several quick connect fittings. I'm going to be installing an air horn, but it's not a priority.
I'm still up in the air as to where to mount the tank-I was considering mounting it underneath my toolbox, but the frame rail has it's appeal. The only issue is that things get crusty in upstate NY winters. Same dilemma with the compressor. Right now I think I'll try putting it under the toolbox as it's mostly wasted space there anyway. If anyone has pictures of there setups, that would be GREAT!
Sooo, I'll post pictures as I do the install. Currently just waiting on a few more fittings and the hoses, but the main components are here. I'd love to hear about everyone else's systems, as well as some feedback on my plans!
