## Description

Be prepared for tire emergencies with the VIAIR 450P Automatic Portable Compressor, the ultimate automatic tire inflator kit that assures dependability whether you are airing up after an off-road trip or facing an unexpected flat tire situation. Tailored for trucks, jeeps, and SUVs with tire sizes up to 42", this portable air pump ensures peace of mind during every road adventure. The automatic portable air compressor is ideal for tire-to-tire transitions or when you want to check pressure mid-inflation. By eliminating manual on-off switching and streamlining the inflation process, our air pump will help increase efficiency and help you get back on the road quickly. The kit comes with a close-ended gas station-style air gun for added convenience. The deluxe dual-compartment carry bag, included with the air compressor kit, enhances portability and storability, ensuring no more scrambling during emergency situations.The tire inflator kit operates on 12-volts, delivering up to a maximum working pressure of 150 PSI and a 100% duty cycle; the free flow capacity is 1.80 CFM. The automatic air compressor operates for up to 1 hour at a time before needing a rest. The engine needs to be running during use for seamless operation.

Review: *** 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: 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)

### ⭐⭐⭐⭐⭐ Review
*by B***N on 12 April 2017*

I do allot of wheeling in my 2016 wrangler jk rubicon. I recently went to a 35 inch tire on beadlock wheels. Before I was running 32 inch tires on the stock wheels and airing down to between 18 and 20 psi. Well just the stock tires burnt my cheap little compressor up. Now I am airing down to 10 psi and this thing is amazing. It affords up all 4 35 inch tires up with no problem and I am not having to travel with low air pressie to a gas station. It's a great air pump and it airs up my tires in a fairly decent amount of time I think it takes about 4 minutes maybe less per tire. And I am not ruining them on pavement looking for a gas station to pump them back up. I would definitely recommend this to anyone who wants a good portable air compressor that wheels allot. Oh and it's very quiet too, which was shocking to me, as I was expecting it to be loud like my other small El cheapo compressor was. Do keep in mind though when using this one or any one like it always grab it by the handle. My nephew can attest that the metal parts get very hot, as all compressors will. Definitely a good buy and I will definitely buy again once this one gives out if I haven't gone to an onboard air system. Quick update. Can't say enough about this little air compressor. It does great on my 35×12.5r17. Now for a real test. I got home with my 07 379exh peterbilt, and had a flat tire. This is a 295/75r22.5 that takes 110 psi. And in about 20 minutes it went from 0 psi to 85 psi. Is it the fastest way to air one up? Nope, but when it is all you habe at home it is great that it can do the job.
