Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Impressed with the Quality of the Compressor and  Accessories
*by A***2 on January 13, 2018*

*** 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.

### ⭐⭐⭐⭐⭐ Portable Air Compressor of the Gods
*by D***N on December 24, 2022*

Works well. We bought this compressor to keep our truck camper and Jeep tires and spares inflated to the proper PSI. The Viair 450P is 100-percent duty cycle. Most portable consumer-grade air compressors are not. The 450P can be used continuously for about an hour, and then needs to cool down for about 15-minutes. Be careful as some parts of the compressor get mighty hot and will definitely burn your hide.The Viair 450P connects to your vehicle’s battery. Make sure the engine is running as the unit has up to 23-amps draw for the compressor DC motor.The compressor is very useful to reliably air up in a timely fashion and to not overheat or damage itself. It is also good for inflating toys and sports equipment. It can also be used to purge the fresh water lines, water heater, pump, and faucets for winterization. It should be used with an air regulator (~30 PSI).One of the best things about the 450P is the synthetic rubber base. The non-skid bottom and feet also limit sliding on most surfaces, and will not damage most surfaces. It works well in sand, on firm mud, and on wet grass, asphalt, and concrete. The base and feet are easy to clean and keep the compressor upright and stable.On the subject of compressors, I have something of a warning story. When I was a kid, I heard about a man that needed to air up a large farm tractor tire. He had a small portable air compressor with a sufficiently large battery, but the compressor output over time was low volume and slow to air up anything. So, instead of staying with the compressor, he connected it to the almost totally deflated tire and then went off to check on other things. He got distracted and forgot to return. I was told the resulting exploding tire was pretty loud, but nobody got hurt.

### ⭐⭐⭐⭐⭐ Best Air Compressor Unit I've Ever Owned
*by M***E on July 29, 2017*

This IS the BEST portable air compressor I have ever owned! Super easy to set up, use, and is so incredibly quiet!! We have a 37' RV with 19.5" tires that need to be at 95 psi. What a pain it was to fill my tires with other units. It took me less time and trouble (love the clamp on for the tire stem) to fill/maintain six tires with the Viair 450 then it took to fill one tire with my previous units. It is so well worth the money - you get what you pay for!!! The only thing I would add is to also purchase the digital inflation gun (approx $35)...getting exact measurements is awesome!! Upgraded to a 43' diesel pusher where the eight (8) tires are 110 psi...and still love love love this compressor and digital handle with clamp on unit...works great! The price is relatively step, but worth it. Trust me, on super cold mornings or super hot afternoons, you do NOT want to be spending a lot of time filling up tires and with this unit, you're not!
