I'm thinking of getting myself a portable air solution but can't decide on which one. I'm heading out to EJS with my buddy in a few weeks and need something for on the trail.

So far I'm thinking of a nice VIAIR solution but can't really decide if I need a model 400PA 33% duty or 450PA 100% duty. I'm looking to fill 4-8 tires from 10-15PSI up to ~30PSI but will the 400 do that without having to take a "break" where the 450 will power through? They look to have similar ratings as far as how quickly they fill a tire. Anyone have more info, like some real world feedback? The 450 is only about 50 bucks more, but is it overkill for what I need?

Also the Smitty seems similar to the 400PA, but 100 bucks cheaper. I'm not thinking I'll be disappointed with either of the VIAIR, but has anyone really used this model a lot? (more than a few times)

 

I've been looking at the same two pumps but the hard mount, Seems the 400 fills faster, but may need to rest. I am thinking the 450 is the way to go, rather have insurance then sit around waiting.

 

the 300 viair does great. it did mine and my friends tj both on 33. same price as the smitty

 

Thanks for the feedback on viair products. I think the smitty is too iffy to buy at this time if noone has any experience with it.

 

I went with the 400, not the portable unit, but still viair 400

Take a look at the jeepswagg deal in the vendor section. $199 for the 400H with a mount included. Add a hose and our at $230 shipped. A good deal

 

I have the Viair 400P. I use it all the time. So far I'm using it with 32's mostly. Now and then I fill up a buddy's jeep also 33's and it does 8 tires but does start to get fairly warm after 8 tires, not so bad after 4 tires. Although I'm happy with it I'd spend $50bucks more and get the 450PA if you have the cash, especially if you have bigger tires.

 

Thanks for feedback...
I'm thinking 400P-A now because I don't have time to install something else when I have a few other things needed first. If you look on VIAIR's site the 400 is a bit faster than the 450 and it sounds like it handles the job I need it to do. I'll look at the onboard option, but leaning towards portable.

 

I like the portable unit since you can take it anywhere. And I did help out another jeeper that required it to be portable, or a long ass hose. You can't go wrong.

 

I did just look at the JeepSwag kit and it looks pretty attractive too. I think I've narrowed my choice down to 400 under the hood version or the portable 400.

 

i just got the 400p yesterday and so far, trying it on a spare 35 on the back, it filled from 10 to 30lbs pretty quick! It was also a lot quieter than I imagined. Sorry I don't have experience with 450 model.
