Should Have Bought This Sooner - When we bought our Ford F-350 Dually and a fifth wheel trailer, I bought a CAD$80 (~USD$60) dual 12/120v air tire inflator. The first time we needed to use it, we found out how slow it was. We needed to raise the air pressure in our four big trailer tires from about 90 psi to 110 psi, with one tire at just 57 psi. It took nearly a half hour to do this, and was so slow that I settled for just 100psi--our friends were waiting for us to finish before we left the meeting point and headed on our way. I was determined not to repeat that frustrating experience. My next purchase was a much faster 12v tire inflator for about CAD$150 (~USD$112). It was much faster and certainly addressed the frustration problem. However, after about an hour's total use, the plastic part that clamps on the valve stem blew off the end of its hose. I was able to get a free replacement under warranty, but after a mere half-hour of use, that one started blowing its fuse every time I used it, rendering it useless. So, I decided that I had to find one that was highly rated and would last. After my experiences with these other ones, I was willing to pay for a good quality tire inflator. Well, the Viair 450P-RV is exactly what I was looking for. It comes with all the attachments you need. It has a long coiled hose and a second extension coiled hose so that you can have the compressor near the front of the truck or trailer to reach the battery in either one yet still be able to reach back to the tires. I was even able to use the battery in my truck and reach all the way back to the trailer tires on our 36-foot fifth wheel. Overall, we're very happy with it. One caveat--we've only got about an hour's use on it so far. From all the reports I've read, it's very reliable so I'm not worried about that at all. However, I can't personally testify to its longevity. A great product, and I really wish we'd bought it much earlier!

Is this product a 33% duty cycle or 100%? Why does it list both specsm** A: There are two different models.....400P-RV runs at 33% duty cycle (The 400P-RV can only run continuously at 100 psi for 20 mins before needing to cool down.) The 450P-RV has a duty cycle of 100% (The 450P-RV is a slower filling compressor, due to the lower CFM, but it can be run continuously at 100 psi for up to an hour before needing to cool down.) **Q: Viair website shows part number for this item as 45057 and this listing show the part number as 45053. which is it?** A: 45057 is only available through RV dealers like united RV, technorv.com or bob hurley rv. This listing is for 45053 **Q: What is tbe difference betweet the 45053 and the 45043? Just the rv kit or the compressor its self?** A: Zack, The compressors are essentially the same. The RV version has extra attachments that help when filling motor-home tires: a 45 degree chuck, a 90 degree chuck and an additional 30ft of air hose. Let us know if you have any other question. VIAIR Corporation **Q: If i already have the 440p can i purchase the rv accessories separately?** A: No, unfortunately the 440P has a different size attachments and it is NOT an automatic compressor.Thank you ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great!
