Which air compressor?

[pugslyyy]

Hard to come by? Ok, that I don't get. Buy your own and have it filled, not exchanged. It only takes a few minutes to fill, even a 10#. Barring that, what's wrong with a 5 lb tank? If all you're doing is picking up the pressure difference from where your compressor falls short it should get the job done with minimal dilution.

Everything you mention about it's performance I agree with, and I'd usually never have one as my primary air source. The only way to know what's left in the tank is weigh it, and that can be problematic, but as a fill-in what's the drawback?

I haven't found any place to fill them around here. Our local welding supply does exchanges and that's it. I agree that it is smart to buy your own cylinder so you don't have to pay rental on the cylinders.

I really wanted to go engine driven as it is much less complex, cheap, and doesn't tax the electrical system. After looking at the engine I just didn't see a way to make it work. My truck(2000 FG) has zero space!

If you are running an automatic transmission look to see if the transmission has a PTO Plate on it. You can run a air compressor off of the PTO. Not sure about the FG's!

Although a PTO drive doesn't like to run continually while driving down the road. So I'd run one when stopped to pump up the storage tank. And use a small 12 volt electric to keep the seat and air horn happy.

I have two compressors on my Motorcoach. One small one for the air horns and braking system on the toad and a bigger 120v electric in the basement to run air tools and tire air ups.

Can't tell you how many times I've helped out Little Ol Grandma's change flat tires on their Coaches with my air hydraulic jack and impact gun on the side of the road.

Once I swap transmissions on my Class "A" from a AT 542 to a AT1000 I'm going to put a PTO Driven York Compressor under it and leave the 120 V at home. I want the basement space back! The 542 has a PTO Plate, just haven't stuck on on it yet.
Figured that as long as the tranny is out! It would be a good time to add it.

I run a small ARB and a CO2 tank on my 4X4. But the CO2 dissapears when people, who are not prepared to air back up, find out I've got a tank full and their tires are aired down!
Hard to say "NO" sometimes! I'd add a York under the hood, but then I'd have to ditch the winch battery.

We used PTO Driven Air Compressors on our trucks when I was still working.

My manual trans does have a PTO hookup. So many tempting things to do with that...hadn't considered an air compressor, but hydraulic winches sure are nice....

I can give a little bit of a review of the VIIAR system that I have been using since around 2010.

I purchased a kit that was similar to this:

Something like this but it was called a VIIAR 650 kit or something similar

http://www.amazon.ca/VIAIR-Xtreme-D...6099020&sr=8-18&keywords=viair+air+compressor

Install was easy, a few hours work and as you can see it does come with everything and then some, even spare filters. It does have an adjustable out going pressure valve with guage and another guage/on off switch to mount in the cab.
I have been using it constantly for five years and I air down for the slightest bit of dirt work and fill up constantly so it has seen allot of use.

I cant say it is overly fast but fills up my tires from 25psi to 65psi in 5-10 minutes or so for all 4, I cant say that it goes to 150psi as I never have had the need to go that high. It is much faster than most other people's compressors that I have seen. I having the two 100% duty cycle units working combined does the trick well. Was cost effective and has lasted now for 5 years, I have one kink in the air hose that is taped up and still works.

I looked into setting up my own york system and it would have been much more work and many of the items that come with this kit would also need to be purchased so I opted for the easier route and got going..... whats the rush filling tires up anyway? Its a good time to get out, stretch, have a look around.........chill.....

I've just finished the install of the engine driven air con pump on my 110. I'm very impressed, even when filling a tyre from flat the compressor was cutting out as it was supplying more air than the tyre could take (engine was just idling).
The compressor (Nippon denso) came from a W124 mercedes that I had lying about.
