- เผยแพร่เมื่อ 31 ก.ค. 2024
- I got a beefier Viair 400P Automatic and decided to do a test / review of it.
I had the baby brother for years and it's great but I wanted something heavier duty to handle my bigger tires.
I did an typical air down then air up situation then went full simulation like we had a flat and needed to get it aired up!

I had one of those for 5 years, it's a great compressor. We aired up our 32" tires and later 35" tires many dozens of times, even 110 PSI RV tires. My JKUR has a built in dual ARB now ( also a great compressor ) but if I needed a portable again, it would be a Viair.
Right on 👍
Finally, have someone who shows how to hook up the air compressor to the battery terminals.
Thanks so much for your video. It helped me with filling up my Travel Trailer tires. Excellent video and easy to follow!
Glad it helped 👍
I went to calibration school in the Navy years ago to calibrate very expensive electronics and meters of various sorts. Analog meters such as this, in general, are seldom accurate at their extremes...low and high. They are most accurate in their mid regions...typically.

Thank you all for your continued support!
Thanks!! I have been considering a Viair 400P unit (versus an ARB dual installed on just one vehicle). This was very helpful.
Glad it was helpful!
You can't go wrong with either of them, I've had both. It's nice having the built in, but it's not portable which can be an advantage. The ARB is also more $$$, but it's also a bit faster. It takes us like 12 minutes to air up four 35" tires with the ARB, including taking out and putting away the hoses and stuff. The Viair takes a bit longer, but even a minute more a tire ( a guess ) is only a difference of four minutes in the end.
Thanks for the video. I take this in the motor home and it works good.
Thank you for the informative video! 👍
Thanks for the video about 6 minutes per tire isn't bad. I hate going to the air pumps after surf fishing and waiting online.
GREAT REVIEW, THANK YOU 😊
When inflating a completely flat tire, it’s always better to jack the tire up for faster inflation takes all the pressure off tire
Same model as the Bushranger Max 3 . Identical in fact except the BR3 comes with digital gauge. Great compressor. Used it 100's of times in deserts and dusty mountains here in UAE.
Viair supplies the Compressors for BR
Fancy man now!!
Great video. Just bought one off Amazon.
Hope you enjoy it!
“I was a little high”. Dude, me too!
Great video
Glad you enjoyed it
You can use a zip tie to hold it down, get the size right and you can just slide it down to hold it down or slide it up to release the trigger
I've been wanting to get one of these for years. Maybe Amazon with have a good Black Friday sale. When I use to go off roading I would just unscrew the valve core to let the air out and then it was a guessing game when to screw it back in quickly.
Thanks! I had a difficult time trying to get the hose attached.
Same! It is a little finicky to get it to seat correctly but it seems strong
Thanks I have the same compressor DRV version because I live on the road in the trailer it comes with two cables so I have greater distance to the back tires on my trailer
Very cool!
Such an enthusiastic review.
Nice video...Viair makes good products. I have the 88p about 4 years now. I had considered the 400 but $250 was a bit much. If I was buying now I would get the smittybuilt 2781 or similar for $165. It puts out 5.6CFM which is double the 400p and it can easily be modified to be automatic with a pressure regulator like the 400p. There are also double piston compressors that put out 10+cfm for about $220.
thanks for the info
@@RobDaman .. Just for further context on that double piston compressor (10.5cfm) - the compressor is a portable one that runs off the car battery. It is marginally bigger than the smittybuilt 2781. I watched a reviewer fill all 4 of his 34" tires on his Toyota pickup. He used a 4 tire hose rig to air up all 4 tires at the same time from 10 psi to 37 psi in 5 min 20 sec.
I am so glad you mentioned the smittybilt. It seems impressive to me, and it is US (Arkansas and Minnesota) instead of China.
Good video. I just picked up the VIAIR 450, but I haven't had a chance to test it yet.
Good choice!
@@RobDaman The 400P would handle my current Jeep TJ on 35's but I plan on buying a Ford F250 and running 37's so I figured I would plan ahead so I picked up the 450 which can fill a 42" tire.
Thanks for the video also getting a 400p. What kind of velcro strap did you get? I was also concerned about having to hold the trigger for 4 tires.
71 degrees? I'm jealous. It's 32 degrees in Philly and we just had a foot of snow.
Ya i heard east coast been brutal. We did get to like 36 one nigh. We can't take that here.
Off topic but I like your wheels! So tired of bling wheels on 4x4's
I was going with the 88p until I discovered the 400p Auto today and now found your video. Would you buy this again and any upgrades or better models for the money in your opinion?
both great compressors. just depends on tire size and goals.
glad you didn't loose bead deflating down to zero
I had the full size spare so it would have been another video otherwise 😉
I'm sorry if I missed it but what's the difference between the automatic and regular compressor?
You can see how I control it in the video. That's automatic
What wheels are those?
Wait, so are you selling the truck or are you buying an air compressor for it? Haha. Or is it one of those "I told the wife I'm selling it, but put it at 50k so I'll never have to ACTUALLY sell it" Haha
Why would you out a brotha like this...
Not as fast as I was expecting ✌️👍🇨🇦
What about the 88p? Does it work with 285 tires? I am between the 88p or the 400.
I've used it on 285s in my other vids. Should be ok
@@RobDaman thanks
Is it possible to mount this in the engine bay? Link?
I haven't seen one mounted but if you have a space for it I'm sure it's possible
Living in the Midwest, hella cold. Will it do well? Longevity?
According to viair minimum operating temp is -40f
www.viaircorp.com/tech#:~:text=Maximum%20operating%20temperature%20of%20158,%C2%B0%20F%20(unless%20otherwise%20noted)
What kind of strap did you say you were going to add to the trigger ?
Just a Velcro one
@@RobDaman Gotcha thanks!
✌️✌️
Have you heard of Traxxas
First off, I am unimpressed with the gauge on the viair. Lastly, I thought "automatic" would mean you could preset the pressure, and it would shut off automatically. Seeing that the gauge is inaccurate, this would not be perfect. I'd have to learn & memorize the offset error of the gauge to make it work if it really was automatic.
I agree. I just used mine for the first time late last night, and I though i wasnt using the compressor properly. $300 for the auto shut off and it doesn have a rocl solid guage!? Come on!
@@FullMetalPatches I went with the Smittybilt 5.6. It's much better.
OK, what wheels are those??

It is kind of amazing people are still using these small battery powered compressors when you can put together a 10 lb CO2 tank system and it will blow away these portable compressors. It will be significantly faster and using a ball valve, there is no trigger to hold down zip ties or otherwise. It is not even close. Another benefit is you can use the CO2 tank to power air tool either on the trail or in your garage.
I'll pass on the 25lb tank mounted in the back of my jk, not to mention the cost and hassle of refills
@@CharlieCheapshot Just wait till your compressor fails when you are out in the middle of nowhere and you are out of cell service!! How much of a genius do you have to be to be that lazy to risk your life?!!!
@@LWRC I'll drive on underinflated tires before letting myself die but you do you "genius"
@@CharlieCheapshot And it takes a special level of stupid to even go down that road considering others have already posted videos on how bad these compressors are. But we all know not every one of you did well even in high school since we saw how brilliant you were back then!!!
damn that takes too long, I'd rather save for a twin arb kit where its portable or a power tank but both are expensive
it's not bad and as you pointed out less expensive vs alternatives.
As good as this is, seems like they are all crap. 6min per tire from dead flat is quite the length of time.
An actual compressor (smallish size) would be better suited imo.
Well the issue was I didn't jack it up as another person suggested so that made it harder to fill possibly. Also smaller compressors usually have shorter duty cycles and CFM. This is a large tire. It makes me think about trying the same test on my smaller 88p come to think about it. 🤔
Don't even bother with a small AC compressor. Just go with a 10 lb CO2 tank!!
