## Overview

The VIAIR 450P is a robust 12V portable tire inflator designed for trucks and SUVs with tires up to 42 inches. Featuring a powerful 1.8 CFM airflow and a max pressure of 150 PSI, it offers a 100% duty cycle for continuous use up to an hour. Its 35-foot durable rubber-braided hose and automatic shutoff function ensure precise, convenient inflation on the go.

## Description

450P-Automatic offers an automatic shut-off function in a larger powerful portable tire inflator. This 100% duty cycle unit is capable of pressures up to 150 PSI and can be operated for up to 1 hour at a time before needing to be rested (at up to 100 PSI). The 450P-Automatic comes with a close-ended gas station-style air gun for added convenience.

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: I have a motorhome - coach diesel pusher The on board compressor takes for ever ( 20 - 30 min per tire ) to go from 100 to 115 - 450 ?**
A: You really need a compressor that's rated for a higher pressure. You're looking to operate at the maximum edge of the pressure rating. It won't blow up per say, but it's not going to be as fast as you need. Look at Max psi closer to 200 psi with 100% duty cycle.

**Q: Is this the best brand for this kind of portable compressor? Looking for most solid/reliable unit with no budget.**
A: This is the best.

**Q: Would it work if i replace the 12v clamps with longer wires / cigarette lighter (male)?  so, i don't have to pop the hood open.**
A: Willie, they're not full of crap, you've just been lucky and haven't run your compressor to a high enough PSI to draw full load amps (it will draw very few amps at 0 psi and max amps at max psi), or you've put a bigger fuse in your cigarette lighter, so you can draw amps until the wires melt under your dash and maybe catch on fire. If this compressor was safe to run on a lighter plug, it would come with the option just like the smaller viair compressors. If you're okay with the risk of a fire under your dash, and you wouldn't mind re-wiring anything that shares the routing through the dash with the lighter socket wires, then give it a try. You can extend the wire(s), but do it to the battery with about 10ga wire and a quick disconnect that insulates the battery end. Napa, or your local knowledgeable auto parts guy, can show you what you need if you give them this description. You can keep the clamp for the ground and find a nice bolt or bracket, then wire your hot near that. 10ga might be a little light on paper, but since you aren't combining it with other wires you won't overheat it. I would pick up an inline fuse (all-weather) and put it very close to the battery in case something shorts your wire, the fuse will blow instead of killing your battery or catching on fire. FYI, if you do make a cigarette plug adapter, the high resistance in the small wires under your dash will reduce the power available to your compressor so it will run slower (all that power reduction goes into heating the wire bundle in your dash; pure physics, and a bad idea).

**Q: Can i run this off a car jump starter pack?**
A: James,We recommend that you run our compressors with constant 13.8V, meaning a recharging car battery (vehicle on) or a converter/power supply for the compressors to operate as specs. Running our compressors with a jump starter or stand alone battery may not give the compressor the voltage that they may need. With low voltage, the compressor will be starving for power and create high amp draw or worst damage the compressor.

### ⭐⭐⭐⭐⭐ 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.
