As usual I am happy with the always excellent customer service and quick shipping. I am however disappointed in the product. This Viar portable air compressor is replacing one I had for over 10-years which was not sufficient for my current needs and was very happy with it for longevity and performance. I am however unhappy with what I received. The photos associated with the unit I purchased showed battery alligator clamps for power, what I received only has a 7-pin connector. This is problematic because Besides my RV which does have a 7-pin connector, I was hoping to use it in our car which does not. Additionally, while my RV does have a 7-pin plug, I understand it will not power equipment that does not have running lights.
Order came four days earlier than promised - very quick delivery on this order. Way to go folks! Registered the product online with manufacturer - cannot wait to use the VIAIR compressor.
I got this to replace a regular 400P Viair compressor that had a very unfortunate hose failure. I guess it speaks to their reliability that despite the fact that the hose on my 15 year old compressor failed I got a new one from the same company.
The automatic feature, meaning that if you lift off the trigger the compressor stops, is really nice. And the automatic 400P has a MUCH better hose. Note that the regular 400P hose, the yellow one, is I think nylon, and Viair recommends it not be used below freezing. Which might have been in part why my old one broke.
It does irritate me that Viair uses a non standard female to female quick release hose. Why not do it like all other air tool set ups? female compressor to male at one end of the hose, female at the other, and male on the tools. Sheesh. In any case, relatively easy to put together a gender switcher (heh) so you could use a regular hose rated for the compressor's pressure.
The gauge on this seems to run a bit high, but again it's better than the regular 400P because if you let the compressor stop you get a true reading. A tad high compared to my regular air pressure gauge and my TPMS, but consistent which is the most important point.
Also, I MUCH prefer the chuck on this. The regular 400P has a non bending metal bit that is tough to fit onto valves on the tires on my truck and some trailers I've used. I had to bend the valve and fight it to get a good connection; it just got in the way of itself. Ugh. This connection is MUCH better. Smooth fitting, and tight.
I noticed it takes a few beats before the compressor turns off after you lift off the trigger. But again, it's consistent so once you know that you anticipate and lift off a bit earlier.
It also has a stickier base, so it doesn't seem to walk around as much. A nice touch.
All in all it was worth it to upgrade to the automatic from the regular 400P even though I was forced into it. Especially since etrailer had it on sale. Thanks etrailer!
The hair hoses already have holes in them compressor still working now

Ron, would you be able to send me pictures of the hoses? They would be covered under the warranty.
Love it! Now I can check and fill tire pressure every
time we hit the road, instead of stopping at the tire,
ware they did not have the chuck to check/fill the outer
rear tire on a dually. Bob
Loving it! Very reliable, easy to use, and have had no issues with it. Happy with our purchase.
Worked like it should happy with it.
Works very well. I use it for inflating tires and pushing liquids out of my RV water supply lines for winter.
I love the design engineering of the pump. 1 year ago I had purchased a smaller pump but it couldn't pump 4 tires to 123m lbs. kept shutting down when it got too hot. Hopefully this on will be able to do that.
there was a defective air filter housing but Viair is supposed to send me a replacement
EASY TO SET UP AND VERY QUICK TO FOLLOW THE USE.
Quick smooth transaction , good communication AAA+
