Looking for opinions on the listed compressor set-ups. I want it for airing up 8 - 33's quickly without a tank. If you know where to get the best price, that would be nice as well. Thanks.

I was looking at the Viair 450Cs off ebay for around $200 but wound up with a C02 tank instead. figure out how much space you have to work with under the hood and get the largest one you can stuff in there. for me it was the 450c. Viair's site has all the specs for you.

Take a look at the duty cycles on the compressors listed and I bet that helps you make up your mind. I murdered two Quick Air II's before switching to my ViAir 550C.

the QA 2 is about the same as the ARB that he already has.

I have a CO2 tank but I want to have a system that's with me 100% of the time and the tank won't be. I've used the ARB a couple times and it's not too bad but I don't want to burn it out. I think I have a line on a Viair 450 so I may go that route instead. Thanks.

Good point, I do want one with a 100% duty rating and it looks like the Viair 450 is the one for me. Do you run a tank with yours? ...Steve

I have the 550C, but the 450C's seem to work well for the folks who have them around here.

I have a 2.5 gallon tank attached to mine, but I don't know if I would bother for the use you have described.

Would a compressor with a 33% duty cycle rating be good enough for the occasional air up of some 32's?

I am looking to just get a portable compressor, just something to hook up to the battery air up and go.

Here's some commonly used numbers for translating duty cycle into run time;

Duty Cycle @ 100PSI & 72 ° F
Minutes On / Minutes Off

10% 3 Min. On / 27 Min. Off or 4 Min. On / 36 Min. Off
15% 4 Min. On / 22 Min. Off or 6 Min. On / 34 Min. Off
20% 6 Min. On / 24 Min. Off or 8 Min. On / 32 Min. Off
25% 8 Min. On / 24 Min. Off or 10 Min. On / 30 Min. Off
30% 10 Min. On / 23 Min. Off or 13 Min. On / 30 Min. Off
33% 12 Min. On / 25 Min. Off or 15 Min. On / 30 Min. Off
100% Continuous Duty @ 100PSI & 72 Degrees F

A 33% unit should be okay for filling one set of 32's, but if you have a buddy waiting, you are going to need to have them wait for half an hour or so before they can begin filling their tires.

For comparison, the ARB compressor has a 15% duty cycle and the QuickAirII is something like 25%.

I always seem to have others waiting for my air when I am done, so a 100% unit was just the ticket for me.

And I mailed you back.

The 550C is mounted in a portable toolbox, then that box is set into my bed toolbox. The reason I did that was to be able to have the compressor "hard mounted" with all the benefits that come with that, but I have had experiences in the past when I needed to be able to move my compressor away from the truck. I can disconnect the air line and power cord, lift the tool box out of the bedbox, plug in a pigtail that has a pair of aligator clips on the other end and carry it to another rig.

You can see a picture of it here; http://www.watrd.com/mods/images/viair.jpg

DC5000 is the best

If you want a good compressor, not alot of money. The DC5000 is the one I have and is the smame one Grumpy is telling you about from puma. Its made in Phx at a company called AIM Industry's. It only uses 18 amps and pushes more CFM compared to Viaair and Quickair. I have wrote up a chart that compares every aspect, and you can't beat the DC5000. I have used if for over 6 months, works perfect. Shane on the AZ board actually got the first one, and I was told to get it. I can air up my 32's in about 8-10 mins. And its Duty Free. I am hooking it up and installed my ARB next week. Putting a 3 gallon tank.

Are there any specs on this DC5000, like CFM, etc?
