Review on 🔧 Efficient and Reliable Viair 40047 400P-RV Automatic Portable Compressor Kit by Demetrius Patsion

I bought a compressor a little over a year ago. Due to the frustrating issues with the tire valve extenders, I actually worked on this one. It's not fast, it's a compromise you make to get high pressure in a small package, but it just works well to get the job done. On several occasions I have had to pump Michelin 275/80R22.5 on my RV from 0 PSI to 95 PSI. It took some time, including a pause, for the compressor to cool down, but I got the big tire up to the required pressure with no problems. I had a case to contact the seller. The inflation gun that came with my compressor was defective, somehow completely clogged. I contacted one of their technicians via online chat. As soon as he understood what I was telling him he said he would send replacements immediately - no questions asked, no returning defective ones, no hassle. It's all a compromise. If you are considering a Viair compressor, which I highly recommend, you need to consider which of the two models is best for you. The attached image is a screenshot comparing some parts of the 400 and 450 series compressors. There is not much difference in price but there are tradeoffs between the two. The comments at the bottom of the comparison columns tell you what to chew on. Once again I have used one of these compressors many times and I highly recommend them. If mine were stolen (I don't think it's going to die anytime soon) I would replace it immediately.
