Review: Impressed with the Quality of the Compressor and Accessories - *** 6 years of use update: Still working great and have not had any issues with the compressor, bag or any of its included parts. Have been using it quite a bit and pack it in the truck for every road trip or trail adventure. Added a picture of the pumps specs*** Bought this for use with my 4WD truck and jeep for airing up my tires. Did a ton of research and decided on the Viair 450P. After getting it and some use I am actually really impressed with the quality of everything that comes with the compressor. The air gun and pressure gauge are well made and seem heavy duty. The pressure gauge reading is about 4-5lbs higher than what it actually is - so would be good to have a 2nd gauge on hand to compare PSI. The hose and clamp on air chuck are both nice - hose is made of nice rubber and the air chuck is heavy cast metal vs stamped steel. The long curly air hose is NOT the typical cheap plastic hose (usually yellow and cracks or shatters after any small amount of time in the sun). It is rubber coated with a woven/braided line. Very flexible and also fits nice into the front bag pocket. The bag seems nice and has plenty of room for everything. Material is a little thinner than I would prefer but zippers are large and smooth and bag has plenty of room for everything. The compressor itself is solid and well put together. Nice handle and base. Fairly quiet in my opinion when running. It pumps up one of my trucks 35x12.5x18 inch 12ply/F-Load tires from 20psi to 45psi in 4 minutes. The auto shut-off feature is great when you are switching to another tire or the other side of the vehicle, as the compressor quits pumping, using power and generating heat. The 450P kit comes with extra air intake filters and some different ends for the air gun (like a needle for pumping up a basketball). The model 450 compressor is rated at a 100% duty cycle, meaning it is built to be continuously run for up to an hour. Other Viair models that have a higher air/CFM output rating, like the 400 & 440, are rated at a 33% duty cycle, meaning they can run for about 20 minutes before needing to be shut off to cool down - see Viair's website for the specs. So depending on your intended use, the 400 or 440 may be a better choice due to the faster fill rates. For me, the benefit of the 100% duty cycle is I can fill my tires (that require a higher PSI) PLUS fill my trail buddy's tires as well, and NOT exceed the rated run time. Overall very happy with this product.
Review: 35" tires - great for offroading - So far this and my other Viair 88 have been excellent products. This one has the very handy feature of shutting off when you aren't actively pumping air. I can't overemphasize how nice that is. The bag is a little thin but it is holding up fine. I'd prefer a little heavier material. There is enough room in the bag to add a patch kit and other small items. Being 100% duty cycle means it will just keep going and going. I chose that over a faster fill but 33% duty cycle because I didn't want to be worrying about or managing cool off periods. A false economy to a faster fill. The faster models also take more amperage, but that isn't a big deal. The hose is really nice that it stretches to all 4 corners of a full-size truck. Overall, very happy with this. I air down from about 38 to 25 psi for mixed offroading and lower for specific needs. This airs up after with no problems at all.

## Questions & Answers

**Q: Is this the RVS 2019 release version?**
A: Hi Mick. Thanks for your question. This is the the 45043. This is basically a closed ended system with automatic shutoff. So as you pull the trigger on the tyre inflators the compressor starts up. It’s very easy to use. Let me know if you need any more information. Very best regards, Matt Savage (Matt Savage 4x4)

### ⭐⭐⭐⭐⭐ Well made compressor.
*by C***R on 12 May 2023*

This is not the fastest out there, but it works very well. 100 percent duty cycle. Very quiet and so little vibration, so much so I was pleasantly surprised. All my other 12v compressors have been noisy, and shake like crazy. The carry bag is nice, the hose and all the accessories are well thought out. One of the situations where you get what you pay for, and I have grown tired of paying for junk. This should last a long time. Happy customer for sure.
