I was on wheelersoffroad and saw the 200H viair on board air pump. I was wondering if I HAVE to have a tank to pump up 33" tires or not? Also what type of electrical connections would I need to be able to run it?

 

[tanKoma]

all the tank does, is store air for use, so that ur not running out the duty cycle of the compressor, the larger the volume of tank, the longer ur air will be consistent, every compressor i used had a tank, as for wiring, u need to have a relay setup so that it can shutoff the psi is at demand

Get yerself a CO2 tank. Those compressors run way slow and cost too damn much. I can fill all my tires in the time it takes those with compressors to fill just one or two. Yeah it costs money to refill the CO2, but $16 in CO2 fills over 30 tires.

air tank definately helps. Do you know the specs on the compressor?
(cfm per minute at a given pressure?)
ought to be a be to rig up a mount for one of those 6 gallon air tanks sold almost everywhere. add a Grainger check valve, camp/huasfield air water separator, plumbing fittings and conduit of choice- a hose reel is a nice touch- and you'll be in business.

i've got a quick air hardmount compressor. It will take 7 gallons from 0 to 120 in about 15 minutes. SO after blowing 1-2 tires up w/ a quick shot from the tank, you can mosey on down the trail a little further , so by the time you hit the blacktop your tank is charged back up for the final air up.

or you can get a refillable CO2 tank.

if u really wanna get hardcore and save some bucks over a electric, look into york AC compressors, they put out twice as much cfm as some of those viare's, only thing you have to fabricate a mount for it to be driven by the belts, though im not saying it will be a success, if ur new to this i would go with the CO2

So where would I fill up a CO2 tank at?

 

[SteveO]

Search for on board air and a thread about CO2. This was all covered in the last couple of weeks in this folder and there were some good reasons for CO2 and comrpessors although it's clear to me that a good compressor/tank set-up is superior to CO2 regardless what California thinks.

 

[tanKoma]

welding supply has the tall cylinders of CO2 i dunno what u need to fill them, another thing i was considering that would be good is to have both setups, a C02 and compressor, one for back up, or where compressor hoses cant reach, the best aspect of CO2, the air is already there, compressor u can use and not worry about how much u have left when ur an hour or 2 from civilization

I guess I am leaning towards CO2 now. Basically this is the problem: Don't like paying or finding gas stations with air. My bed box is full of tools and camping stuff along with half my ext. cab(have a 3 seater basically now). I can't put that stuff anywhere b/c I am at school and it is easy to have and store their. With CO2 when I get a bed bar I could make a point to strap down a CO2 tank right(along with CB, lights, hi-lift), there would be room?

I went with a compressor and tanks because I didn't want to have to load up a CO2 tank everytime I went wheeling and have to be concerned about running out or it freezing up in the winters here. The main reason though was I knew that when I needed air for something I wouldn't have the CO2 tank with me but I'd always have the compressor. I also use it for blowing up rafts etc and it's nice not to have to find a place to store it on the truck when wheeling and then have it sitting in the garage when you're not using it. Search the other threads and decide what matters most to you.

Steve,
How do you have your compressor setup on your truck?

 

[SteveO]

Here's the compressor on the passneger fender well.

Here's the tanks before I mounted them.

And here they are mounted under the bed.

Works good, enough air to run air tools and will fill up the first tire from 10-30pSI in under a minute an then takes about 2 minutes for the second and 2.5 for the other two while the tanks are refilling. Fast enough for me and most important to me, unlimited air and it's always there when I need it. .....Steve

I was wondering about the efficiency of such a set up verses a non belted pump such as the Vair or similar.

I have also wondered about a 120volt setup with a powerinverter for pushing more CFPM.

Anybody with thoughts on a power inverter, air compressor set up?

 

[ZR2Steve]

I have never checked or did the math, but my wag is the $350+ you spent for an inverter plus the $100 for a 110v compessor and the cost of a 2nd battery setup would buy a GREAT 12volt unit.

DANG thats 1.87 per tire! I'd rather take a bit longer to fill, and since a lot of guys have pumps that your waiting for to finish filling up, might as well be filling yours too and save money in the long run.

 

[Dick Foster]

Yeah and that CO2 expands and contracts with heat a lot more than air does too.

I can understand the hurry to get wheeling but airing up gives me a chance to hook up the sway bar and kinda look things over just after I've finished brutilizing the truck off road.

I agree that it's more than I want to pay but you should check your math. It's closer to 50c per tire.

Well duh, divided the numbers backwards didn't my retardo butt!
